High Vaultage

An uninterrupted urban plane encompassing the entire lower half of England and, for complex reasons, only the upper third of the Isle of Wight. The immense Tower casts electricity through the sky, powering the mind-boggling mechanisms of the city. The engineer-army of Isambard Kingdom Brunel swarms across the capital, building, demolishing, and rebuilding whatever they see fit.
