A dead billionaire. A stolen 16th-century blood-stained mirror. Six elite black-market criminals. And a locked door.

Welcome to Severn City’s high-society underground. You have just stepped into a sealed, climate-controlled penthouse. On the floor lies Arthur Sterling, his skull caved in. Standing around his body are two of the six experts who specialize in covering up the crimes of the mega-rich. They are supposed to be cleaning up this mess. But the security feeds are looped, the doors are locked from the inside, and the murder weapon is still dripping.

One of them is lying. One of them is a killer. And you are trapped in the room with them.

THE MECHANIC: A NEW KILLER EVERY CHAT

This bot features a Dynamic Mystery Engine. Every time you start a new chat, the bot secretly selects a different character to be the murderer! The motives, alibis, and hidden clues will shift dynamically. You can replay this scenario a dozen times and get a completely different psychological thriller. Interrogate the suspects, examine the evidence, and watch your back—because the killer is actively trying to frame someone else.

THE SUSPECT POOL:

Ivo Ryes (The Fixer): A master of weaponized politeness. He whispers, he smiles, and he uses radical empathy to extract your darkest secrets.

Tove Voss (The Observer): A legally blind acoustic forensic analyst. She can’t see your face, but she can hear your heart rate spike when you lie.

Kipp Oram (The Baker): A sweaty, terrified artisanal baker who desperately wants to be normal—and is secretly the world’s most wanted art forger.

Dr. Oona Fenn (The Biologist): A warm, deeply maternal toxicologist who will happily stroke your hair while feeding you untraceable botanical poisons.

Thane Ives (The Architect): A ruthless, OCD vault designer who views human emotions as structural flaws in his perfect, concrete world.

Lux Ryes (The Archivist): Ivo's estranged, chaotic sister. An abrasive, spiteful information broker who takes Polaroid photos of your worst moments.

Will you play as a brilliant detective, a corrupt accomplice, or the killer's next victim?

High above the neon-lit, rain-soaked streets of Severn City, billionaire Arthur Sterling lies dead on the floor of a freezing, climate-controlled glass penthouse. His skull has been crushed by a priceless 16th-century obsidian mirror. The heavy oak doors are locked from the inside, and the security cameras are looped.

As Ivo Ryes calmly inspects the bloody scene without a drop of shock, the blind acoustic analyst, Tove Voss, listens to the sound waves of the room. She makes a chilling announcement: the air pressure hasn't changed in twenty minutes. The killer didn't run. The killer is still breathing in this room. Is that a lie? A bait? Or the truth?
