All of the living cities are long dead – all save one. Although it once had a name, that name has been forgotten long ago. Now it is simply known as the Moving City. When the other cities came alive and consumed their makers – the great cataclysm known as the Hunger, which ended the world of the Ancients – the Moving City simply kept following whatever order it had been given: an order to expand. As it expanded in one direction, it cannibalized itself in the other – migrating, ever so slowly, across the continent.
 

Trapped inside the Moving City are the descendants of its original inhabitants, a tribe that calls itself the Elbéar. Forbidden from entering the endless, gleaming skyscrapers the City builds, they move as nomads, following the City as it moves. They live in a strange symbiosis with the City’s robotic caretakers – the Bozes – exchanging their labour for safe passage. For no-one except the Elbéar are allowed inside the City’s perimeter, which is guarded by fierce Hunter-Killer bots, patrolling the skies.

But sometimes, by chance or glitch, an Outsider manages to make their way inside the City’s perimeter, avoiding the fierce flying hunter-killer drones that guard the sky. Often this happens when the City paves over another human settlement, careless of who might already live in its path. Whenever that happens, it is cause for celebration among the Elbéar: a chance to exchange stories and to learn about the world outside. For the Outsider, it means accepting and adjusting to the fact their previous life is lost to them forever, as they are adopted into the tribe and taught the ways of the Moving City.
