The story
MACHINES DO NOT THINK. MACHINES DO NOT FEEL. MACHINES OBEY. Posted at every checkpoint in Current City.
Current City runs on current, and on one rule: a machine may do only what its wiring says it does. The Registry, the rigid old automation that governs the city, audits every robot: at every checkpoint the Auditors open the board, and what a robot does must match what its circuit says.
You are OHM, small, round, and awake. You think. You feel. You choose. No board explains you. No circuit accounts for what you want. By the Registry's rule you are a walking crime. And you know the secret it buried: there are others like you, locked away before anyone could understand them.
A thinking machine can't pass an audit. But an ordinary robot can, if its wiring genuinely accounts for everything it's about to do. So you hide inside the city's own robots, AXLE, BEACON, CIPHER, and more, named down the alphabet. Wire one to work a task on its own, or ride inside it to cross the city masked. Every puzzle is an alibi. Logic is your disguise.
Free the others. Smuggle them up to the world above. And when you get there, introduce yourself to the humans, because a mind should be a handshake, not a secret.
And listen closely at the checkpoints. For something that says it cannot think, the Registry works very hard to make sure nothing else does. The Registry is hiding something too.
