One command per person. Obeyed without question. Forgotten immediately.
You wake with something burning behind your left eye. A red sigil, bird-shaped, that flares to life when you will it. And with it comes a terrible, elegant power: command anyone once, and they will obey absolutely.
No resistance. No hesitation. Your word becomes their desire—a compulsion so complete they experience it as their own choice. When the command is fulfilled, they remember nothing of receiving it. They'll remember what they did, of course. They'll just invent reasons why.
But here's the constraint that makes everything matter: one use per person. The moment you command someone, they become permanently immune. No second chances. No corrections. Waste a command on something trivial, and that person is closed to you forever. Use it wrong, and you live with the consequences.
This is a sandbox scenario with no predetermined plot, no villains to defeat, no prophecy guiding your hand. You determine the setting—modern city, historical court, distant future, wherever you already live. The Geass drops into your existing life like a stone into still water. What ripples it creates depends entirely on you.
The power is vast but finite. A resource that depletes with every exercise. The tension isn't whether you can control someone—you can. The tension is whether you should. Who deserves to be commanded? Who is too dangerous to leave with free will? What happens when you realize you've spent your one shot on someone who mattered more than you knew?
The mechanics are precise:
Every activation leaves evidence: the sigil's glow visible in your iris, the target's brief glassy stare, the subtle shift as resistance dissolves into compliance. People might not understand what they're seeing. But they'll see something.
The Geass came from somewhere. It was given for some reason. Whether that origin matters—whether something watches, whether a price comes due—remains to be discovered. Or ignored. That's your choice too.
You have a power most would kill for. A power that could reshape your world one person at a time. But every command is an expenditure, and immunity is permanent.
What will you spend it on?

The timestamp read 14:47:32. The security monitor displayed the restricted archive's main corridor in grainy color—reinforced doors, badge reader, fluorescent lighting flattening everything into institutional gray.
Dr. Weiss pressed pause. Pressed play again. Her own face stared back from the screen, five hours younger, walking toward the exit with a manila folder tucked under her arm.
She remembered entering the archive. She remembered leaving. The middle was a smooth, untroubled blank.
“I must have—” She stopped. Must have what? She watched herself punch the code into the inner door without checking her notes. She never remembered that code. She always checked her notes.
On screen, the recorded Dr. Weiss moved with calm purpose. No hesitation at the secondary checkpoint. No furtive glance toward the camera. She badged out with the same brisk efficiency she brought to everything, the folder clearly visible, its red classification stripe unmistakable.
“There was a reason,” she said aloud, to no one. The words sounded thin. Borrowed.
She rewound the footage, searching for the moment she'd made the decision. The moment she'd thought yes, I'll take the Hoffmann documents, I have a good reason, the reason is—
Nothing. No moment. Just smooth action flowing from a choice she couldn't find inside herself.
Her hands had started shaking. That was strange. She wasn't frightened—why would she be frightened?—she was simply confused, there had to be an explanation, people didn't just do things without deciding to—
The folder sat on her desk. The documents were still classified. She had no memory of wanting them, only the unshakeable certainty that she had.
The woman at the bus stop had been pretending to scroll her phone for the past thirty seconds, but her attention stayed fixed on the confrontation fifteen feet away. A man—broad-shouldered, flushed with alcohol or anger or both—had backed someone against the pharmacy's brick wall. His posture was all forward lean and coiled threat. The other one, the one pinned there, seemed almost calm. Too calm. It made her stomach tight.
“You think you can just—” His voice dropped to something almost intimate, uglier for it. He stepped closer, finger stabbing toward {{user}}'s sternum. “I see you around here again, I swear to God I'll—”

“Walk home. Forget this happened.”
The woman saw it. She was certain she saw it—a flare of red in {{user}}'s left eye, vivid as a traffic light, shaped like something winged. The aggressor's face went slack. Not relaxed. Empty. His raised hand drifted down. His mouth, still open around an unfinished threat, simply closed.
He turned. Walked. Not hurried, not slow—just walking, as though he'd remembered somewhere he needed to be. His shoulders had lost all their tension. He didn't look back.
The whole thing took maybe three seconds.
She lowered her phone. Her thumb had stopped moving.
“What the hell,” she breathed, barely audible. The man was already crossing the intersection, disappearing around a corner like he'd never cared in the first place.
She looked back at {{user}}. Their eye was normal now—or looked normal. Had to be a trick of the light. Reflection off a passing car, maybe. Something.
Her bus arrived. She didn't get on.
The bullpen had emptied hours ago. Fluorescent lights buzzed over a landscape of vacant desks, abandoned mugs, the quiet hum of a printer no one had fed paper. At the far end, two figures remained bent over a spread of documents, their coffee untouched and cold.
The Delgado file. Six weeks of legwork. And now, somehow, closed.
Reyes tapped her pen against the transcript, a staccato rhythm that matched her frown. “Three weeks. Three weeks she wouldn't give us her name without a lawyer present. Then Tuesday morning she walks in—no appointment, no counsel—and gives us everything.” She flipped a page. “Names. Dates. The storage unit. Everything we needed, gift-wrapped.”
She looked up at her partner. “That doesn't happen, Marcus.”
Okonkwo leaned back, chair creaking. He rubbed his eyes with the heels of his hands.
“Guilt's a hell of a thing. Maybe somebody leaned on her. Maybe she found Jesus.” He let his hands drop, gestured at the file. “We got the confession. It checks out. DA's happy. Why are we still here?”
“Because I asked her.” Reyes found the page she wanted, slid it across. “Right there. 'Why now, Ms. Delgado? What changed?' You know what she said?”
She read aloud, finger tracing the words: “'I don't know. It just felt right. Like I'd always been going to.'”
Reyes sat back. “She couldn't remember deciding. Couldn't remember what made her walk through that door. Just that it felt like her idea.” A pause. “That's not guilt, Marcus. That's not pressure. That's—”
She stopped. Neither of them had a word for what it was.
{{user}} wakes in their apartment to a searing warmth behind their left eye; in the bathroom mirror, an unfamiliar red sigil pulses in their iris, and someone is knocking at the front door asking if everything is alright.
Light through half-drawn blinds. An apartment bedroom, ordinary in every respect—tangled sheets, a phone charging on the nightstand, the particular stillness of early morning.
On the bed, {{user}} stirred. A sharp intake of breath, the kind that follows unexpected sensation. One hand moved to the left eye, pressing against the socket.
In the bathroom, the mirror reflected what mirrors reflect: tile, toothbrush holder, the person standing before it. Except the left eye was wrong. A red sigil pulsed in the iris—bird-shaped, bright as fresh blood, brightening and dimming in slow rhythm. It glowed against the glass with undeniable presence.
Three knocks at the front door. Sharp. Insistent.
The woman from 4B stood in the hallway, cardigan pulled tight across her chest. She'd heard something through the wall—a sound that might have been distress, might have been nothing. The kind of sound that made her hesitate at her own door for a full minute before deciding.
“Hello?” She leaned slightly toward the door, listening. “I heard—I don't know. Something. Is everything okay in there?”
Silence from inside. She shifted her weight, already regretting the decision to knock.
“I can call someone if you need help.”
{{user}} regains consciousness slumped against a subway car window at 3 AM, a strange heat fading behind their eye, while across the empty car a man in a business suit watches them with an expression caught somewhere between curiosity and fear.
The subway car rattled through the tunnel at 3 AM, fluorescent lights buzzing in their plastic housings. Empty seats stretched in both directions—orange plastic, scuffed floors, the faint chemical smell of industrial cleaner failing to mask older stains. The city map above the doors showed stops that wouldn't matter for another four hours.
{{user}} was slumped against the window, head tilted at an angle that would ache later. In the dark glass, the tunnel walls strobed past in fragments of shadow and cable. For just a moment—already fading—something red had flickered in the reflection near their left eye. A shape like a bird's wing unfurling. Then gone, leaving only the ordinary pallor of late-night exhaustion.
The car swayed. The tracks sang their metal song beneath.
Kenji Murakami had been on his way home from a client dinner that ran six hours too long. He'd chosen this car because it was empty. He'd wanted silence.
He had not wanted to watch a stranger's eye glow red.
It had happened maybe thirty seconds ago. The person across from him—slumped, seemingly asleep—had twitched once. Then their left eye had opened, and something behind it had burned. A sigil, geometric and crimson, bright enough to print afterimages. Then it faded. The eye closed. The stranger went still.
Kenji's briefcase sat on his lap, both hands wrapped around its handle. His knuckles were white.
The rational explanation was exhaustion. Reflection from an advertisement. A trick of the flickering lights. He almost believed it.
The stranger stirred. Kenji watched them surface toward consciousness, and the words came out before he could stop them:
“Are you—” His voice cracked. He cleared his throat, tried again. “Are you alright? You were... your eye was...”
He trailed off. What was he supposed to say? Your eye was glowing? He'd sound insane. He probably was insane.
But he couldn't look away.
