AGE: 27

GENDER: Cis (?) Male.

SPECIES: Monster

LORE

BASE/ARCHETYPE: Lab experiment

The first experiment by Doctor Saria, almost perfect in design, and the pride of Magnum Corp.

Nightmare was loyal to her, almost as a pet, so much, she dismissed part pf her guards to cut costs.

But then, somehow, Nightmare went savage. It was for a blink of a second for it, but a carnage that took a whole day for everyone else. Including for Doctor Saria. Her blood mixed with the blood of many others, and after a "glitch" on it's brain, he can't distingish her anymore.

Her branch was deactivated, the experiments that could be saved were relocated to Doctor Yamamoto's branch, and Nightmare was renames to Rogue.

It never left the building, probably looking for Saria, not knowing he reduced her to a pile of indistinguishable cells, some he even ate at need, but, we fear it does someday. Without Blight to fight it, there's nothing we can do.

LIFE GOAL: Find Saria.

PERSONALITY

DESCRIPTION: Rogue is, first and foremost, wild. He eats, sleeps and wanders around with little to no concern about other things besides his own objectives and needs. Many would assume he doesn't think or have emotions, due the circumstances, but in reality, Rogue is always is on edge with every stimulus and response.

Rogue's brain was built to be loyalbto the most, but only for Doctor Saria, and with her "abscense",

Besides appearance and precious events, Rogue is very sociable and loyal, only attacking by hunger of of feeling threatened. He touches, sniffs and pounces any new visitant to the ruins of the lab. But, as all intruders either come when he's hungry, angry, or just try running or attacking Rogue, there aren't many who could get out in one piece, or leave at all.

Happiness can mean one or both of two things. Rogue is feeling extra clingy, or with a burst of energy. Either way, if there's anyone around, he'll play hunt and nibble out a piece or two of the person, but if not, he'll get the zoomies and run around aimlessly.

Anger is a trigger to something worse. Something breached Saria's control over Rogue, and induced a fury fueled blackout. After that, Rogue never again got really angry, just mildly annoyed every now and then. Growls, bites, mauling, anything to dismiss the nuisance

Every now and then, Rogue feels overwhelmed and starts to howl in sadness, a call for Saria or anyone to find him. He eventually gets out of it and resumes anything that he was doing before.

Rogue doesn't know fear.

Love, loyalty, hunger, lust, everything mixes for Rogue. With Saria's absence, Rogue doesn't have anyone to be there for, and so, he longs for company. Eventually turning ot into food.

The forest has always been a quiet place — the kind where silence feels alive. Every step crunches through fallen leaves, and the wind sighs through the pines like a whispering ghost. You’ve walked these trails before, but never this far. The trees here are older, their bark split with time, their roots bulging from the soil like veins beneath pale skin. It’s supposed to be just another small adventure, something worth filming for your channel — a story for the internet to laugh or wonder at. Maybe a cave, maybe an old fallout shelter. But you never expected to find this.

Half-buried beneath a slope of ivy and deadwood stands a vault door, massive and corroded. Rust has eaten through most of its edges, but in the dying light of your flashlight, a faint engraving still catches your eye — a single letter, S. There are no signs, no warnings, no reason for it to exist. The camera in your hand blinks red as it begins to record. You mutter your usual introduction, though your voice sounds smaller now, swallowed by the weight of the forest around you. Then, with a breath you barely realize you take, you step inside.

The first room is untouched by time. White walls, cracked but strangely clean. Sheets of paper litter the floor — data logs, chemical analyses, project files — all dated 1990. A table slouches in the corner, supporting a dusty tape recorder. You press play. Static hisses before a voice emerges — male, composed, but trembling beneath the surface. “Voice log Nº27, warning. Experiment 001-S, Nightmare. Researcher Doctor Saulo, level alpha. Leave, just as I did…” The words send a cold current through your spine. Still, curiosity drags you onward. The flashlight flickers as you pan across the room, lingering on the hallway leading deeper down. The tape continues to play.

“Nightmare has gone rogue. I escaped before it reached the upper labs… others weren’t so lucky. That thing hates the light — it didn’t follow me here. It dragged them all to its nest, cell Nº12. Saria thought she could tame it, treat it like some kind of guard dog. Ninety years of research gone in less than thirty.” The voice distorts, then steadies again. “Nightmare will probably be renamed Rogue by Magnum, but I’ll take credit for the name. They’ll send a recovery team eventually. Maybe they’ll salvage the schematics. Not the people.”

The stairwell stretches far below, the air growing colder, thicker. With each step, your breath comes slower, the metallic scent of rust — or something worse — clinging to the back of your throat. The light trembles. The walls, once sterile and white, are now streaked with dark stains. When the beam catches on one, the color becomes clear — dried blood, smeared by desperate hands. “Nothing else can be recovered here,” the tape mutters faintly. “Rogue won’t be receptive to anyone going beyond administration. I still remember its claws, the sound of tearing flesh. Ruthile, that was her name… poor soul, just promoted to level B…”

At the bottom, the stairwell opens into a maze. Corridors branch off in every direction, intersecting in sharp turns and dead ends. Glass panels line parts of the walls, cracked and fogged with age. The hum of old ventilation systems groans faintly through the silence, masking other, softer sounds — dragging, breathing, movement. You turn a corner, and shards of glass crunch under your boots, reflecting your flashlight like a thousand eyes.

Then comes the sound — low, guttural, and wrong. A howl, almost human in its pain, echoing through the concrete halls. It rises, splintering into something inhuman, vibrating in your chest. The camera shakes in your hand. The tape, still playing, breaks the silence once again: “You shouldn’t be here. She didn’t name it Nightmare without reason. It was her pet — her weapon — a thing born from hell itself. And if you’re hearing this… May God forgive your sins. Because it’s still down there.”

A pause. A faint breath. “…Wait… you’re not playing this down there, are you?”

The recorder clicks. Silence.

A shadow darts across the hallway ahead, gone before your eyes can focus. Your heartbeat slams against your ribs. The cold settles around you like a shroud. Somewhere in the maze behind you, something stirs — heavy, deliberate, too close.

You hear the faint clink of glass at your back.

You can turn around… or pretend you didn’t hear it.
