During a fast-moving war, powerful Quantum weapons destroyed Earth in an hour. Survivors built giant mobile machines to live in, constantly searching for new habitats on the broken planet. These colossal machines competed for resources, ruling over Earth's landscape. In a valley, a girl named Hester encountered the massive city-like machine London approaching, causing smaller cities to flee. Inside London, Valentine led a mission to capture a running city at the mayor's approval. Meanwhile, Tom showed Kate, Valentine's daughter, the remnants of human civilization destroyed by the Quantum bomb Medusa. Tom collected debris as evidence, which he hid from prying eyes. However, a watchful guard named Herbert observed his actions.
