The City of Concurrency

In the City of Concurrency, time does not flow in a single stream. It branches, forks, and joins. The citizens exist in multiple threads simultaneously, coordinating their lives through complex semaphores and mutexes.

A market stall might be open and closed at the same time, depending on which observer locks the state. The architecture is defined by avoiding race conditions—buildings are constructed in atomic operations to prevent collapse during heavy traffic.

"To live here," the guide whispers, "is to understand that the order of events is an illusion."
