A hyper-city built on the bones of New York, walled against a fog that makes monsters and unmade by the crowding of the living. Step through the gate.
A fog came, and the world learned what it was for. Where people thinned, it made monsters — things that grew the longer they were left alone. They were beaten by only one thing: the weight of the living, crowded close.
So the nations died and the hyper-cities rose, walled and packed, because distance was the same as death. Argent is the largest of them, grown over the drowned bones of an old American city, gate to gate, dome to bay.
Everything you are is written down somewhere. The only question the city never answers is who keeps the pen.
The founding immortals of Argent. Each carries a sealed question in the chest. None of them will tell you the answer.
You make a self, you declare at the gate, and you find out what the city does with you.
The Sleepless is a story you run inside Argent, not one you read about it. You build a person — a body, a history, maybe an origin nobody chose for you — and you take them through the gate into a world that answers. Run a job for one of the houses. Talk your way past a checkpoint, or don't. Bleed, or get out clean. The city has its own people with their own reasons, and they remember what you were the last time they saw you. Nothing resets politely to zero. What you did stays did, and the world goes on keeping its books whether you're looking or not.
Two bridges in, two bridges out. You declare what you are at the threshold — every time, no exceptions. Then the city lets you through.
