Sigma AU Meta - why so many characters?

Writing Characters in Sigma AU

I create in-depth characters to show what’s happening in different parts of Sigma AU. They aren’t always part of the main story but exist to give context to how the world works in different areas. Some of these characters are expository—their role is to reveal history, consequences, or mechanics of the setting. Others are exploratory—their role is to push into unfamiliar territory and open new perspectives in the world.

Expository Characters

Expository characters are the ones tied into Sigma AU’s foundations, created to explain how its institutions, legacies, and scars function. They show the costs of war, experimentation, and survival.

  • Etrius vanRandr — centerpiece of the Petrovich’s Legacy duology. His arc exposes Petrovich’s experiments, St. Petersburg under Ravenna, and the long-term consequences of Soviet remnant science.

  • Ravenna Wildfire — also part of Petrovich’s Legacy, her tyranny in St. Petersburg shows what happens when Petrovich’s creations run unchecked.

  • Voss — born from cult attempts to resurrect Ravenna, her very existence explains the lingering reach of Petrovich’s notes .

  • Red Vorten — the official Russian counterpoint to Etrius, Ravenna, and Voss. Through Project Zvezda-14, she embodies Russia’s brutal black-site programs and the human cost of total erasure.

  • Zoey Lavender — Sigma City’s mercenary fox, and Zayara’s direct opposition. She embodies the excesses of Sigma City, cybernetic survival, and the chaos that flourishes outside controlled systems.

  • Queen Zayara — Zoey’s antagonist, an alien cobra whose obsession with genetic perfection frames the ideological clash between order and chaos.

  • Zola Pozhar — Etrius’s wife, stranded from another universe. She explains how outside forces bleed into Sigma AU, and how magic competes with technology.

  • Vladimir Petrovich — the architect of Etrius and Ravenna, he is the human face of Sigma AU’s legacy of experimentation.

These figures are expository because their stories directly explain why the world is the way it is.

Exploratory Characters

Exploratory characters are not about the foundation but the expansion. They are sent into uncharted regions of the world to show what life looks like beyond Sigma City and its core conflicts.

  • Ilia Bluepaw — China’s engineered panda, showing post-nuclear PLA remnants and how transhumans operate outside Western frameworks.

  • Saitō Benkei — Japan’s swordsman, blending martial discipline with transhuman design, exploring Japan’s recovery and traditions after WWIII.

  • Vlasta Korolivska — Ukraine’s viper soldier, defected and wandering, showing how Eastern Europe’s battlefields shaped their own transhuman programs.

  • Dozer — France’s contribution, providing insight into French survivorship and resilience.

These exploratory characters are built to answer the question: “What does Sigma AU look like outside Sigma City and St. Petersburg?”

Other Roles

Some characters don’t sit neatly in either category, existing more for context or personal reasons.

  • Bestalsh — my own take on a deathclaw-like being

  • Taylor Wolfe — my wife’s character, not heavily involved in-universe.

Sigma AU: What is and isn't canon?

As the writer of an alternate universe parallel to our own that is still in active development, one must consider, that with newer stories and information that facts may collide with older lore.

The Sigma AU adopts a "newest content takes precedence" approach to lore accuracy, and older lore entries may be updated silently to address this.

As time goes on, characters, ideas, attitudes, and places all change. The Sigma AU's "current"  state is at the turn of the century, and unless explicitly stated, all short stories take place over the course of 2100.

The primary writing focus of this blog is creative exercise and self-expression. Lore accuracy is paramount, and often, lots of time is spent making slight adjustments to ensure that events are congruent.

Dates will be constantly altered to reflect the constant influx of information constantly being created, both as primary content and supporting material.

Given the Sigma AU is an alternate version of our own universe, choices have to be made regarding what in our world carries over to the Sigma AU.

The stance taken is that unless explicitly stated, nothing has changed. The most significant events of the Sigma AU takes place after 2035. After careful consideration and review of past materials, many, many writers never thought that their creations would still be relevant to the consumers of such media, and have hastily tried to predict the technology of the future.

The Sigma AU's lore heavily focuses on real world established technology with a few grains of salt in the future. For example, the prosthetic arms worn today are powered by batteries. Today, we also have piezoelectric generators that can generate electricity from simple movement. We have ultracapacitors that can store electricity just as well, if not better, than batteries. Given the futuristic setting of the Sigma AU, and the death of Moore's Law, the technology in the Sigma AU is defined as a refined version of what we already have, giving plausibility to it.

As far as genetic engineering goes, our world already has clones, and we've successfully created hybrids. We can replace bones with titanium. One man even cured his own genetic disease using CRISPR. Reason stands to say that in the future, this technology is improved upon, allowing us to create the hybrids present in Sigma AU.

We also have awarded prizes to people for proving that alternate universes exist using quantum physics that the average person is far too stupid to understand. We've also used particle accelerators to open our own microscopic black holes, which are thought to be portals to these other universes.

These details don't necessarily prove the validity of the science fiction aspects of the Sigma AU, but rather disprove the invalidity of it, which is slightly different.

That being said, enjoy this fiction for what it is, and take safety in that the reality to the fictional characters who live in it very well could exist in some alternate universe. 

Sigma AU Short Story - The Lines We Cross

The first blast rolled through the district like a fist, a hard concussion that made the glass skyscrapers shiver and threw every conversation, every car horn, every step into silence for a single second before the screaming started. The air filled with dust and the metallic stink of ruptured power conduits. Zoey’s head snapped toward the column of smoke blooming between two office towers three blocks away. Etrius was already moving.

She broke into a trot, armored boots slamming against the pavement, Titan servos whining as she picked up speed. Civilians poured past her, a tide of suits and bags and panicked faces, some covered in blood from flying glass. Traffic had already collapsed into a deadlock of abandoned cars and blaring alarms. Etrius cut between vehicles with precise, long strides, shoving a man aside before he got trampled in the stampede.

SCDF comms lit up in their ears, clipped reports cutting through static. “Unit Five responding to blast zone, fire suppression en route.” “Possible secondary devices in grid 8-A, evacuate pedestrians from central plaza.” “Crowd control units needed at Towerline Interchange, mass panic underway.”

Etrius barked into his mic. “Ghost and Warlord on-site, moving to epicenter.” He didn’t wait for permission. He vaulted a crashed delivery drone and dropped into a low sprint.

Zoey’s armored fists smashed aside the bent frame of a security gate that had buckled in the blast, clearing their path. She moved like a machine, helmet HUD cycling through thermal and optical overlays as she scanned the smoke column. “Blast was focused,” she said, voice metallic through the suit speakers. “Not random.”

Etrius spared a glance as they rounded the corner, shrapnel scars were concentrated inward, glass blown into the street. “Directed charge. They hit infrastructure, not people.”

“Not yet,” Zoey muttered, pushing forward.

They cut through a side street where civilians were still struggling to get clear. A child sat screaming on the pavement, ankle caught under a chunk of fallen concrete. Zoey stopped just long enough to rip the slab away and haul the kid to his feet before shoving him toward a cluster of SCDF medics fighting their way in.

The smoke was thicker here, heat rolling off the pavement. The outer wall of a credit exchange had been ripped open, exposing steel beams and fire-belching conduit. Alarm klaxons were deafening at this range, automated sprinklers hissing steam as they tried to suppress the blaze.

Etrius scanned the wreckage, sword unhooked but idle in his hand. “This wasn’t meant to level the building. It’s disruption. First strike to trigger evacuation.”

Zoey turned her head, the Titan’s optics catching movement at the edge of the smoke. Two figures, masked and carrying rifles, sprinting deeper into the district.

“Contacts,” she snapped. She didn’t wait for acknowledgment. She launched forward, glass crunching under her boots. Etrius followed, plasma sword up, green eyes narrowing as the first bursts of automatic fire cracked through the haze.

Pedestrians screamed again and hit the ground. Bullets sparked off Zoey’s chestplate, glancing away as she closed the distance. Zoey's PTRS-41 spat a single, concussive shot that tore a small crater into the pavement, sending one of the shooters sprawling. The second turned to run.

Etrius dropped him with two precise cuts to the legs, then advanced, blade still steady. “You’re done,” he said flatly, stepping past the writhing man to clear the alley’s far end.

Zoey grabbed the first attacker by the collar and slammed him against a wall hard enough to rattle his teeth. “Where’s the rest of you?” she demanded, voice amplified to a roar.

The man spat blood and said nothing. She raised a fist, but Etrius’s voice cut across the comms. “We don’t have time. Move.”

She let the body drop and turned back toward the avenue. More gunfire echoed to the east, another cell opening up. Screams followed, higher and sharper this time.

Etrius reloaded without breaking stride. “They’re spreading out. We cut them off before they get civilians pinned.”

Zoey’s gauntlets clenched. “Good. I hate running.”

Together they plunged deeper into the smoke, leaving the first scene of destruction behind them, heading toward the next.

Gunfire echoed like a chain reaction, rolling through the canyons of glass and steel. Zoey moved first, Titan servos whining as she took a corner at speed, her heavy frame scattering shards of broken window. Etrius kept pace behind her, plasma sword stowed now in favor of his M1911-50, firing precise single shots to drop any figure moving with a rifle. Civilians lay flat wherever they could find cover, under eaves, behind wrecked vehicles, pressed against walls with their hands over their heads.

They reached the first intersection and found three more attackers pinning SCDF officers behind a disabled patrol carrier. Zoey didn’t break stride. She went through the wreckage, Titan boots crunching over twisted metal, her antitank rifle hosing a single, devastating shot that turned one gunman into a spray of red mist against the concrete barrier.

Etrius swept left, firing controlled pairs, dropping the second before he could recover from the shock. The last man threw down his rifle and tried to bolt, but Zoey caught him one-handed by the back of his webbing and slammed him into the ground hard enough to crack the pavement.

Etrius was on him in a second, boot on the man’s chest, pistol at his temple. “Where are the rest?”

The man spat curses in a language Etrius didn’t speak. Zoey’s gauntlet came down, not as a punch but as a warning, a clang against the pavement next to his head. “Talk, or you won’t get a second chance.”

The prisoner shook his head, blood pooling under his cheek. No answer. Etrius cursed under his breath and pressed forward; there was no time to argue. “SCDF’s got this block. Move.”

They left the prisoner for the arriving officers, Zoey’s armored silhouette disappearing back into the smoke.

The next cell was better organized. As Zoey came through an underground loading ramp, an IED detonated at her feet, tossing her into the wall. The Titan’s armor held, though the plating was scorched.

“Still up,” Zoey growled, pulling herself out of the crater. Etrius vaulted the ramp, cutting one attacker down with his sword before the man could reload.

The rest opened fire, hammering the concrete around them with rifle rounds. Zoey shouldered through the storm, Titan optics locking on heat signatures. She fired her rifle, and the confined space filled with dust and blood as the last of the ambushers went down.

When it was done, the smoke hung heavy in the loading bay, tasting of propellant and ozone. Etrius kicked the last rifle away and crouched over a dying grunt, pressing a knee to the man’s chest. “Why here?” he demanded. “Why the Business District?”

The man bared bloody teeth and laughed. His accent was local. “Paid,” he rasped. “Paid to make your precious President look weak. Paid to make SCDF run like rats.”

Etrius leaned closer. “Who paid you?”

The man’s grin widened despite the blood in his throat. “Doesn’t matter. Top floor of Delta Finance Tower. They’re waiting. Whole city’s going to watch them die.”

His breath rattled once, then stopped. Etrius stood, wiping blood from his gloves on the man’s vest. “We’ve got a target,” he said, voice clipped.

Zoey was already moving, climbing the ramp. “Then we go. Before the show starts.”

They broke into a run again, vanishing into the smoke and sirens, heading for the tower.

The Business District narrowed as they neared Delta Finance Tower, the streets funnelling them into a canyon of glass facades and gridlocked vehicles. Fires burned unchecked in upper floors, raining embers into the avenues below. The Titan’s optical sensors highlighted movement ahead, heat signatures darting between the wrecks, setting up hasty defensive lines.

Zoey didn’t slow down. She plowed through an overturned taxi, the frame screeching as it split. Bullets sparked across her chestplate, ricocheting into the street as she charged. Etrius moved parallel through the shadows of the curbside awnings, firing precise shots into firing ports and dropping shooters one by one.

The closer they got to the tower, the tighter the resistance became. Two attackers with RPGs fired down the avenue, one detonating short, showering the street with glass and shrapnel. Zoey staggered under the blast, armor scorched black, but she kept going. The second shooter reloaded too slow; Etrius’s plasma sword cut him cleanly across the torso as he came around the corner.

They breached the tower’s perimeter through a side loading dock, finding bodies, SCDF officers already cut down by the first wave. The lobby was a mess of broken glass, torn banners, and overturned furniture. The elevators were locked down, red lights flashing across the panels.

“Stairs,” Etrius said, checking the ammo counter on his sidearm. “We climb.”

Zoey’s voice was calm, almost bored. “You climb. I’ll take the fast way.”

He shot her a look but didn’t argue. They split without ceremony. Etrius pushed through the lobby, clearing the first stairwell with surgical precision, stepping over bodies and keeping his breathing steady. His focus narrowed with each floor, hearing distant gunfire and the occasional scream echoing from above.

Outside, Zoey ran for the side of the building, slammed her gauntlets into the steel facade, and began climbing. The Titan’s claws and weight tore gouges in the surface as she hauled herself up, using exposed beams and window ledges when she could find them. Glass shattered under her boots, raining onto the street below. Her breathing stayed slow, calm, the climb a rhythm she’d done a hundred times before.

Halfway up, a terrorist leaned out of a broken window and opened fire. Rounds sparked off the Titan’s pauldrons as Zoey swung one-handed, grabbed him by the vest, and yanked him out into open air. He fell silently into the chaos below.

By the time she reached the roof, Etrius was clearing the final stairwell. He drove his sword through the chest of a defender blocking the last landing and shoved the body aside. Zoey smashed through the glass skylight and dropped into the top-floor hallway, landing with a crunch that crushed a grunt under her boots.

She straightened, brushing glass off her shoulder, and caught Etrius pulling his blade free from another man.

“Guess I’m not late,” she said, visor glinting under the emergency lights.

“About time,” Etrius replied, cleaning the sword on the dead man’s sleeve. “I was running out of targets.”

“Plenty left,” Zoey said, motioning toward the hall where the hostages were being held.

Together, they advanced, silent but sure, moving toward the final room where the remaining terrorists waited.

The hostage room was hot, the air stale from shattered ventilation. Emergency lights strobed faintly in the smoke, casting long, thin shadows across the kneeling figures. Hostages were lined up against overturned desks, some with zip-tied wrists, others gagged. The surviving terrorists had been disarmed, forced to their knees at gunpoint. The silence was thick, broken only by the hum of the Titan’s servos and the faint whimpering of civilians.

Etrius stood in the doorway, plasma sword still lit, its glow reflecting off the blood smeared across his arms. Zoey loomed just behind him, her visor burning red. The two of them had the room locked down, no one was leaving unless they decided it.

“They go to trial,” Etrius said, his voice carrying in the tight space. “We bring them in alive, we hand them over to SCDF command. You know what a public trial will do, it will show this city that order still holds. It gives the President a win.”

Zoey’s helmet tilted slightly. “You think anyone cares about a trial? People care about seeing them dead. This is faster.”

Etrius took a step in, the blade still raised but pointed away from the prisoners. “Faster isn’t the point. Capture means information. Capture means dismantling the network behind them. You think this ends if we butcher them right here? There’ll be ten more tomorrow.”

Zoey’s voice came back like iron. “Good. I’ll kill those too.”

The argument escalated. The hostages stared wide-eyed as the two shouted over the bodies on the floor, voices sharp enough to cut. Etrius’s tone was controlled but angry, hammering every point: political stability, SCDF morale, proof that the city’s law wasn’t a joke. Zoey’s voice was louder, colder, cutting through his logic with simple, brutal finality, none of that mattered if these men lived to inspire more chaos.

“You think I care about giving some politician good optics?” she snapped. “My job isn’t to make the city look clean. My job is to make sure no one tries this again.”

“And you think slaughtering them in front of civilians will do that?” Etrius barked back. “You’ll give them martyrs. You’ll make them legends.”

“They’re not martyrs if no one’s left to care,” Zoey said, stepping closer until her armored bulk filled the space between him and the prisoners.

Etrius’s grip on the sword tightened, then loosened. He stared at her for a long second, jaw set, then deactivated the blade. “Fine. I’m leaving the choice to you. Do what your heart says, and clean up whatever mess you decide to make.”

He turned his back and walked toward the stairwell, his boots ringing against the steel floor.

Zoey stayed perfectly still until Etrius’s footsteps faded down the stairwell. The sound of the last door shutting echoed faintly, leaving only the thin rasp of breathing from the hostages and the quiet creak of metal from the Titan’s joints. She felt the room watching her, fear, anticipation, judgment, but none of it moved her. Inside the suit, her pulse was steady. This was the part of the job that was simple.

She stepped forward, the Titan’s boots grinding glass across the floor. The lead terrorist flinched as she loomed over him. His eyes were wide, darting between her visor and the corpses of his men. Zoey grabbed him by the front of his vest and yanked him upright, bringing his face level with her helmet. She made sure he could see his own reflection in the mirrored visor, not the woman inside, just the faceless machine that had killed its way here.

“I’ve just decided to spare you,” she said, voice filtered through the Titan’s speakers, calm and almost conversational.

For a fraction of a second, his features softened. Hope cracked through the fear. She felt it, the way his body loosened slightly under her grip, and she crushed it. She drove her serrated combat knife up under his jaw and into his face with one clean motion. The helmet’s mic caught the wet, tearing sound. Blood sprayed in a fan across the floor and over her armor. His body convulsed once, then went slack.

She let him drop like a bag of meat and turned to the next man. There was no hesitation, no flash of anger or pleasure. Her motions were clinical. She knelt, pinned him in place with one gauntleted knee, and shoved the knife through the side of his skull. The Titan’s servos whined softly as she leaned in, ensuring the kill was immediate.

The others tried to twist away as she moved down the line, but the zip-ties held. Each time, the knife struck with the same precision, the same measured force. The helmet cam recorded everything, the digital timer in the corner counting the seconds of silence between each kill.

Her thoughts stayed cold and practical. No speeches, no threats. Just work. These were not enemies anymore, they were unfinished business. Leaving them alive would mean appeals, rescues, more blood later. Killing them meant closure.

When the last one stopped twitching, she stood. Blood had spread across the floor in a wide sheet, soaking into paper, pooling around chair legs, dripping into the seams between tiles. She wiped the blade clean on a dead man’s vest, then holstered it on the Titan’s thigh mount.

Zoey’s visor panned toward the hostages. Most of them were crying. A man was covering his child’s eyes. Another sat frozen, hands clamped over his ears. They looked at her like she was another disaster, not a savior, not a soldier, just another thing they had barely survived.

Her HUD pinged softly, confirming the camera feed was still transmitting. She stared at the red recording icon for a moment, then let it run. Let them see it. Let the city know what happens to men like this.

Zoey stepped back from the bodies and just stood there, letting the room’s fear settle on her like dust. There was no triumph in it, no rush. Just the faint sense of something closing. She hailed SCDF’s emergency channel and said, flat and final, “Extraction required. Top floor secure. Perpetrators have been executed.”

The response came through the comms a few seconds later, but she didn’t listen to the words. She shut the channel off and waited in silence, blood drying on the Titan’s armor, watching the hostages tremble until the sound of boots and shouted orders from arriving SCDF units filled the hall.

Zoey didn’t speak when the first SCDF troopers stormed the room. The hostages cried out at the sudden movement, some dropping flat to the floor, others clutching at the armored figures as they were gently pulled away from the blood and glass. Orders barked over radios, boots thumped, body bags were dragged in. None of it moved her. She stood where she had been, the Titan’s systems humming softly, the red smear across her visor still half-dried.

Etrius was gone, just like she knew he would be. He hadn’t waited to see the result. The stairwell door was already shut, no trace of him except the clean arcs of blood where his boots had crossed the hallway outside. That absence said more than anything he could have told her. He had left her here to face the civilians alone, to stand in the room with their horror and their gratitude mixing into something sharp and ugly.

She enjoyed it.

One of the SCDF medics glanced at her as he helped a hostage to her feet. His visor was tinted, but she could still feel the weight of his stare. It wasn’t fear, not exactly, but it wasn’t thanks either. It was begrudging appraisal, deciding what kind of monster would do this and still be standing calm among the corpses. She turned away from him and started toward the far side of the room, glass cracking under the Titan’s boots.

She paused at the exit, looking back once. The hostages were huddled together, some whispering, some sobbing into their hands. One man stared at her openly, face blank except for the tear tracks down his cheeks. His eyes didn’t look grateful. They looked like they were memorizing her faceplate, locking her into memory as something to fear. He was right to do so.

Zoey keyed open the Titan’s external speakers long enough to say, “SCDF will get you out. Stay down until they tell you to move.” Her voice came out flat, mechanical, without comfort. Then she shut it off, turned, and pushed through the door.

The stairwell smelled like hot metal and blood. She descended only far enough to reach an emergency maintenance hatch, then forced it open and stepped out into the wind at the building’s edge.

The city below was still burning in patches, sirens and drones filling the air with overlapping sound. SCDF convoys were pushing through the streets, lights flashing. Evacuation zones glowed with emergency beacons. From this height, the Business District looked like a wound, scorched, blackened, still smoking.

Zoey stood there for a long moment, watching it all without speaking. Her HUD kept trying to pull SCDF updates, but she dismissed them, leaving her visor dark. This wasn’t the time for chatter. Her breathing stayed even inside the suit, her muscles loose, but the quiet was heavy, dragging at the edges of her thoughts.

When she finally climbed down, she didn’t return to SCDF command to file a report. She didn’t go looking for Etrius. She walked away from the tower on foot, keeping to the alleys where the smoke was still thick, letting the city swallow her. The helmet cam was still rolling, capturing her slow departure past barricades and emergency lights until she finally shut it off with a flick of her wrist and left the feed to upload later.

No one tried to stop her. No one asked her to explain. SCDF had their hostages back and their bodies to count. Whatever she had done here would be analyzed and debated later, but for now, the Business District was quiet except for the low rumble of fire suppression drones.

By the time she reached the edge of the district, night had fully set in. The fires still glowed behind her, reflected in the Titan’s blackened armor as she crossed back into the outskirts. She never looked back.

Zoey’s little plot of land was still as dead as the day she’d bought it, a stretch of scrub earth and half-buried concrete foundations, ringed with rusting fencing and the distant glow of Sigma City’s outer ring. The sky above was a dull brown haze, light pollution bleeding across it like a wound. She trudged up the gravel path to the APC she called home, servos in the Titan suit whining softly, the weight of the day’s fight still caked across the armor in dried streaks of blood and soot.

She didn’t exit the suit right away. She stood just outside the APC, staring at the ground while the wind hissed across the open lot. She was alone, and the silence pressed in on her like a second skin.

She keyed open the Titan’s chest seals and stepped out slowly, the air hitting her sweat-slick fur in a rush that made her shiver. The suit stood there, still bleeding heat into the cool night air. She left it like that and walked barefoot over the hard-packed dirt until she reached the edge of the lot.

Her prosthetic hands felt sticky even after she’d wiped them clean, as if the blood had worked its way under the metal and stayed there. She flexed her claws, staring at them in the dim light spilling from the container’s doorway. There was no remorse gnawing at her, not exactly. She had done what she set out to do. The hostages were alive. The attackers were dead. But the satisfaction was thin, almost hollow, like chewing grit.

She sat down heavily on an overturned concrete block, elbows on her knees, letting the night air cool the sweat and blood on her. Her mind kept pulling back to the room at the top of the tower, the sharp smell of blood, the way the hostages had gone quiet when the last man fell, the blank stare of the one who had watched her without flinching. That face stayed with her, floating in the smoke like a burned-in image.

Her MeTube notifications were already piling up on her wrist display, hundreds of thousands of new views, clips of the helmet feed spreading like wildfire across the city. Comments were streaming in faster than she could read them, and she didn’t try. She shut the display off with a flick of her wrist. The thought of watching her own footage didn’t disturb her, but she didn’t need to see it. She knew every frame by memory already.

Inside the Mantis APC, the dim glow of her terminal illuminated the metal walls. She didn’t sit at it. She didn’t record a debrief or write a report for SCDF command. There was nothing to explain. She lay down on the cot instead, boots still on, staring at the ceiling until her eyes adjusted to the dark. The smell of smoke still clung to her fur, and she let it, as if washing it off would erase something she wasn’t ready to lose yet.

Sleep didn’t come. At some point she sat back up, and leaned against the doorway, looking out over the silent land. The city lights pulsed in the distance like a living thing, the towers of the Business District still faintly glowing with emergency spotlights. She imagined Etrius somewhere far away, maybe back at his penthouse, maybe nowhere near at all, doing what he always did, staying busy so he wouldn’t have to think.

The night stretched on without relief, and Zoey stayed in the doorway, half-shadowed by the glow of the APC’s terminal. Her hands had stopped shaking, but the restlessness had not faded. It sat under her ribs like pressure, a constant tightness that refused to ease.

Out in the distance, the glow of the Business District was still visible, a faint bruise on the horizon. She imagined the SCDF forensic teams still working, cataloging bodies, zipping up bags. There would be reports filed before morning, orders drafted by noon. Her name would be somewhere in all of it, appended, footnoted, turned into something clinical. Killed by Warlord. Neutralized with extreme prejudice. Every word stripped of heat and smell and sound, turned into a statistic that politicians would point to on talk shows.

The thought didn’t anger her. It didn’t comfort her either. It just felt empty.

When she finally lay down again, she stayed on her side, staring at the wall. The cot creaked under her weight. Her tail twitched once, then went still. The silence was so complete that she could hear her own breathing.

Somewhere, a faint vibration in the terminal signaled another wave of messages. She ignored it. MeTube would keep spinning, the helmet feed would keep spreading. Somewhere, millions were watching her work on repeat, frame by frame. Some of them would cheer. Some of them would vomit. Some of them would say it was staged. The noise of the city would churn and argue, but out here it was just her and the smell of old blood.

Zoey shut her eyes and let the image of the hostage room come back one last time. The way the man had stared at her, like he was memorizing her face. The way the blood had spread under the bodies, reaching out in thin lines like veins across the tile. The way her own voice had sounded when she told him she’d decided to spare him. It didn’t feel wrong. It didn’t feel right either. It just felt finished.

Sigma AU Short Story - One Step Forward

The undercity was quiet in the way only deep concrete could manage, sound dampened, light swallowed, air thick with the faint metallic chill of recycled ventilation. Red’s unit was dim, the amber lamps low enough that the corners of the room dissolved into soft shadow. The LED on the armor cradle blinked in its slow, steady rhythm, like a muted heartbeat.
Zoey knocked once, a short, soft thud with her knuckles, just enough for Red to hear, not enough to startle. Red opened the door almost immediately, like she’d been standing just behind it.
She looked… calmer than usual. Her spotted fur was brushed smooth, her ears relaxed, eyes a muted brown instead of the volatile amber or hazel she wore in public. Her tail hung low, not anxious, just resting. The sweatshirt she wore hung loose on her frame, sleeves pushed up to her forearms, bandaged wrists still healing cleanly.
Zoey stepped inside, ducking slightly under the low lintel. The room felt warmer with her in it; her broad frame and dense musculature tended to do that. She pulled the door shut behind her, horns brushing the air as she moved, tail curling once before settling behind her.
Neither spoke at first.
Red watched her with the kind of focus she usually reserved for hostile environments, quiet, sharp, attentive. Zoey set her jacket on the back of the nearest crate-turned-chair and straightened. The soft red glow from the lamps caught along the carbon-fiber plating of her prosthetic arms, throwing faint highlights across the claws built into her fingertips.
“You good?” Zoey asked, voice low.
Red nodded once. “Yeah.”
It wasn’t a habitual lie. It wasn’t deflection. Just honest. A rarity for both of them.
Zoey stepped a little farther into the room. Red followed her movement with her eyes, head tilting slightly, not calculating, not assessing threat, but something more animal, more subconscious. She stayed close to the wall but didn’t brace against it.
Zoey noticed the difference immediately. Red’s breathing was slow. Shoulders loose. No twitch in her hands. No silent inventorying of exits.
“You seem… better,” Zoey said quietly.
Red’s ears flicked once. “I guess I am.”
A soft, almost shy huff left her. She looked away for half a second, then back. And then she took a deliberate step forward, closing the gap between them in a way she never had before.
Zoey didn’t move. Didn’t reach. Didn’t react beyond a small shift of weight to accommodate Red’s proximity.
For a moment, there was nothing but the soft hum of the ventilation and the quiet rhythm of both their breaths.
Red lifted her hand, slowly, deliberately. Her spotted fingers brushed Zoey’s wrist, just the edge of warm fur meeting cool synthetic plating. A light touch, barely there, but a touch all the same.
Zoey held perfectly still. Her eyes half-lidded, golden in the dim light, watching Red and not pushing her.
Red’s voice dropped to a whisper. “You can stay a while?”
Zoey let a small, warm exhale slip out. “Yeah. I can stay.”
Red didn’t smile, she rarely did, not fully, but her shoulders eased, and her thumb traced a small motion along the ridge between fur and carbon fiber on Zoey’s arm.
Red didn’t pull her hand away. If anything, she drew a fraction closer, just enough for Zoey to feel the warmth of her breath against the front of her suit. Her fingers tightened lightly around Zoey’s wrist, testing, not gripping. Zoey adjusted her stance, lowering her shoulders slightly in a silent yes.
Red’s eyes lifted to meet hers. Brown, soft, searching. She wasn’t masking anything tonight, no sharp amber, no defensive gray, no brittle green. Just the quiet, unguarded brown she only ever showed in moments like this.
Zoey kept still, letting Red take the lead.
Red’s other hand came up, sliding over the front panel of Zoey’s exploration suit, fingertips brushing over the reinforced seams. She knew every line of this suit by now, knew which panels were flexible, which ones folded when Zoey breathed. Her touch wasn’t hesitant. It was deliberate. Purposeful.
She stepped closer. Close enough that the tips of her claws grazed the base of Zoey’s throat where the suit opened into a wide V. 
Red wasn’t trembling. She wasn’t folding in on herself. She was steady.
She leaned in, her forehead brushing Zoey’s chest, inhaling deeply, taking in Zoey’s scent, heavy with warm fur, metal, and the faint bite of toxic drugs.
Zoey lowered her head, bringing her mouth near Red’s ear. “Red…”
“Don’t talk,” Red murmured.
Red’s hands slid upward, both of them now resting over Zoey’s chest. She tipped her chin up, eyes locking on Zoey’s. “I want to.”
She didn’t specify what. She didn’t need to.
Zoey’s heart thudded once, hard, under Red’s palms.
Red rose onto her toes, closing the last inch between them, and kissed her. It was soft. Slow. Careful.
Zoey answered in kind, just the faintest pressure, just enough to match Red’s pace. Her hands didn’t move, didn’t clutch or pull. She let Red control everything.
Red’s lips parted slightly, her breath warm and unsteady, and Zoey met her halfway. Red’s tail lifted faintly behind her, curling once in instinctive motion before settling again.
Zoey dipped her head lower, deepening the kiss by a degree, nothing more. Red responded with a low sound in her throat, something halfway between a sigh and a hum, her fingers sliding up to the base of Zoey’s jaw.
They kissed again, slower this time, lips brushing in feather-light passes like they were learning each other’s rhythm.
Red pulled back, just an inch, her breath warm against Zoey’s mouth. “Bed,” she whispered.
Zoey nodded once, heat flooding her chest.
Red took her hand and led her across the room toward the cot without looking back. Their claws and prosthetic fingers intertwined awkwardly but intentionally, neither adjusting grip, both accepting the imperfect fit.
The cot creaked as Red sat down on the edge, pulling Zoey closer by the hand. Zoey stood over her, towering, but softened her posture to not loom. Red looked up at her with something raw and wanting in her eyes.
“Come here,” Red said quietly.
Zoey finally let herself touch Red, just a hand on her waist, fingers resting lightly against the warm, soft fur under her sweatshirt.
Red leaned into it immediately, exhaling hard through her nose, the first real crack in her composure.
Then she tugged Zoey down.
The kiss that followed was deeper. Needier. Red’s claws slid into Zoey’s long black hair, pulling her in while Zoey kept her touch unbearably gentle, as if Red were something fragile despite her strength.
Red broke the kiss only long enough to whisper, breathless against her mouth:
“I want you to take this off.”
Her fingers tugged at Zoey’s suit collar.
Zoey’s muscles tightened under her fur, heat coiling through her as she met Red’s gaze.
“Okay,” Zoey breathed.
Zoey dipped her head so Red could reach her without stretching. Red slid her hands along the front seam of the suit, claws tracing the reinforced V-shaped opening. At her full height, Zoey had to kneel to be level with Red sitting on the cot, but it didn’t feel awkward, just natural, practiced, the way they’d learned to move around each other.
Red hooked her fingers under the collar and pulled.
The upper section of Zoey’s suit peeled open with a low hiss from the pressure seals. Warm fur spilled out where the plating parted, deep red, dense and soft over the heavy muscle underneath. Red pushed the opening wider, slow enough that Zoey could stop her at any point.
Zoey didn’t.
Red slid the suit down past her shoulders, revealing more of her fur and the broad lines of her torso. Her prosthetic arms shifted with the motion, carbon plating catching the light. Red’s eyes flicked over the transition from fur to synthetic metal, and she ran her thumb along the seam where the prosthetic met living muscle.
Zoey inhaled sharply through her nose, as if to say, "Don't."
Red didn’t say anything. She just tugged again, pulling the suit down to Zoey’s waist. Zoey used her claws to free the lower fastenings, letting the heavy material drop to the floor.
Now Zoey stood over her, towering, warm, fully bare except for her prosthetics. The glow from the room cut along the curve of her hips, the hard shape of her thighs. She wasn’t posing. She wasn’t trying to be anything. She was just there.
Red’s breath hitched once, quietly.
Zoey stepped closer, lowering herself until her left knee touched the floor beside the cot. It brought her down to Red’s height without making Red crane her neck. Zoey placed a hand on Red’s thigh, just resting there, not pushing.
“Your turn?” Zoey asked, voice low.
Red swallowed, nodded once, and lifted her arms so Zoey could pull her sweatshirt up and off. Zoey did it slowly, carefully navigating the lines of Red’s furred ears. The fabric slid away, revealing the mottled cream and dark spots across Red’s shoulders and chest.
Red’s breathing changed, not panicked, just deeper, heavier.
Zoey brushed her knuckles along Red’s ribs in a silent question.
Red exhaled. “Keep going.”
Zoey unfastened Red’s pants next, tugging them down over her hips. Red lifted herself just enough for Zoey to pull them free, leaving her fully naked in the low amber light.
Red didn’t hide. She didn’t curl inward. She let Zoey look.
Zoey didn’t stare or flinch. She took her in with the kind of attention that felt like listening, seeing her body, all of it, without judgment or hesitation. She reached out and placed a warm, steady hand on Red’s side, just above the hip.
“Red,” she murmured, “are you sure you want this?”
Red’s pulse jumped under Zoey’s hand. Her ears flicked back. For a moment her breath stuttered, uncertainty pressing in from the edges.
Her eyes shifted color, brown to hazel, a flash of green, then brown again. Her hands trembled. The earlier confidence cracked as something old and sharp clawed its way up through her nerves.
Zoey’s voice softened immediately. “Hey. Red. Look at me.”
Red did, but only barely. Her breathing was too fast now, shoulders tight, body pulled thin like she was bracing for something she couldn’t name.
“I, ” Red started, then stopped. Her claws flexed. “I don’t know. I thought I did, but now, ”
Her voice caught completely.
Zoey moved closer, still kneeling so Red didn’t feel crowded by her height. She brought one cold, metal hand up to Red’s cheek and held it there gently, letting Red lean into it or push away if she needed to.
“Okay,” Zoey said quietly. “Then we stop.”
Red shook her head once, a sharp, anxious flick. “No, I just, dammit, I don’t know what’s wrong with me.”
Zoey slid onto the cot beside her instead of in front of her, easing Red into her arms without force. Red went stiff at first, breath still rapid, her muscles coiled with leftover fear.
But Zoey held her, steady, warm, quiet.
“Nothing’s wrong with you,” Zoey murmured into her hair. “You got scared. That’s all.”
Red’s breathing didn’t even out right away, but it didn’t get worse.
Zoey kept one arm around her waist and one hand on her back, rubbing slow, grounding circles through her fur.
Red’s voice was small when it finally came out against Zoey’s chest.
“I still want to. I just… need a minute.”
Zoey nodded, brushing her cheek along the top of Red’s head. “Take all the time you need. I’m not going anywhere.”
Red closed her eyes, leaning fully into her for the first time.
The panic ebbed. Little by little. Breath by breath.
When Red lifted her head again, still naked, still trembling slightly, her voice was clearer.
“I want to keep going. Just… slower. Really slow.”
Zoey nodded, kissed her forehead, and eased her gently back against the pillows, her movements unhurried.
“Then slow is what we’ll do.”
Zoey stayed where she was, half-propped against the cot’s frame, giving Red room to move however she needed. Red shifted closer, one knee brushing the outside of Zoey’s thigh. They were still pressed together in silence, not tense, not charged, just breathing the same slow air again.
She touched Zoey’s shoulder, running her fingers along the heavy curve of furred muscle until they hit the sharp transition into synthetic plating. Her thumb traced the seam, feeling how the metal flexed subtly beneath her touch. Zoey didn’t guide her or move into her hand, she stayed still, letting Red take the lead exactly the way she’d asked.
Red’s gaze swept downward. Now that her panic had ebbed, she actually looked at Zoey, and visibly recalibrated. Zoey sat relaxed, not posturing, but her body was enormous. Broad chest and thick, powerful arms made her look like she could fold the entire cot in half without trying. Her hips were wide, thighs thick with muscle beneath the dense red fur. Even sitting hunched slightly so Red wouldn’t have to reach up, Zoey still took up space like she was carved for it.
Red exhaled very quietly. “You’re… big.”
Zoey huffed a small, warm sound through her nose. Not smug, not teasing, just acknowledging. “Yeah.”
Red’s hand drifted lower, sliding over the line of Zoey’s ribs. The off-white fur there was softer, dense enough that her fingers sank a little with each pass. She moved slowly, almost studying her, mapping out the size, the texture, the way each breath expanded Zoey’s torso under her palm. Zoey shivered once when Red’s claws brushed the side of her chest, but she didn’t interrupt.
Red leaned in to kiss her again.
Zoey answered gently, keeping her serpentine tongue carefully under control, barely letting it slip past her teeth so it wouldn’t overwhelm Red. Red’s claws curled lightly in Zoey’s hair when she felt the forked tip brush her lower lip. A small, surprised sound escaped her throat, not startled, just noticing.
She pressed closer, climbing partially into Zoey’s lap without much thought. Zoey shifted to support her, bracing one prosthetic hand on the cot and wrapping the other carefully around Red’s waist. The metal plating was cool but steady against Red’s fur. Red settled astride one of Zoey’s thighs, her body dwarfed against Zoey’s frame but not swallowed by it. Just held.
Red’s hands roamed, tracing along Zoey’s sides, over the thick fur of her abdomen, up to the strong curve of her neck and what was left of her shoulder. She paused at Zoey’s horns, fingers brushing the ivory curls as if verifying they were real. Zoey leaned into the touch with a low, barely audible growl of approval.
Red explored like she was trying to understand how someone so massive could move so quietly. Her palms flattened against Zoey’s hips, sliding along the thick muscle there, then traveled back up to the middle of her chest. She took in every ridge, every shift under Zoey’s breath.
Zoey didn’t rush her. Didn’t ask for anything back.
She ran her snout lightly along the side of Red’s jaw, just a brush, a silent I’m here. Her tail slid around Red’s legs, warm and heavy, curling loosely in a protective arc without actually holding her in place.
Red’s breathing deepened as she explored, but there was no spike of panic this time. Just warmth. Curiosity. A low, simmering desire softened by safety. She leaned into Zoey’s chest with a small sigh, resting her forehead above the curve of Zoey’s collarbone.
Zoey kissed the top of her head, slow, careful, her lips warm against her hair.
Red moved again, but slower now, tracing her fingers across Zoey’s chest, her ribs, her stomach. Her movements gradually lost their deliberate rhythm. Every pass of her hand became lazier, softer, drifting.
Zoey could feel the shift happening. Red wasn’t stopping, she was winding down. Her breathing had gone deep and steady, her body melting into Zoey’s warmth instead of holding tension. The desire was still there, faint under the surface, but muted by exhaustion and comfort.
Zoey stroked her back, long, steady passes of her hard metal palm from shoulder to hip, matching Red’s breaths. She didn’t say anything, didn’t need to. Red’s fingers slowed more with each rise and fall of Zoey’s chest until they finally stilled, resting flat against her side.
Red’s head dipped, leaning fully into Zoey’s shoulder. Her tail draped over Zoey’s thigh, relaxed and heavy. Her eyes slid half-shut, lashes lowering over the brown that had softened completely.
Zoey shifted her weight and eased them both down onto the cot. Red followed without resistance, clinging lightly as Zoey lay back. Red curled into her immediately, head tucked under Zoey’s jaw, one leg thrown over her hip, hand splayed across Zoey’s ribs.
Zoey pulled the blanket up around them and wrapped her arms around Red’s small, warm frame. Her tail curled near Red’s knees; Red’s tail draped over her thigh.
Red breathed one last, quiet sentence against Zoey’s chest, barely audible:
“…stay like this…”
Zoey tightened her arms around her. “I will.”
The room dimmed into soft stillness, their bodies fitting together in a way that needed no more movement, no more escalation, no more heat. Just warmth.
Red’s breathing slowed, evened out.
Zoey listened to it until she drifted off beside her.
