Steampunk Star Wars: Death Star

Massive Solar-Orbiting Electro-Mechanical Analytic Engine, Mark 6

This enormous Imperial space station, the size of a small moon or asteroid, is in fact an immense analytic engine, a device capable of making millions of calculations every day. Inside is kilometer after kilometer of tubes and wheels, cranks and gears, all spinning and clacking, spitting out an endless series of numbers for the Imperials scientists to decipher.

Although the Empire has half a dozen such devices in operation throughout the galaxy, this version is unique. While the others spend their days crunching statistical algorithms or calculating flight models, the Mark 6 station (under the personal watch of Lord Vader) is dedicated to experiments with Arcane Mathematics, the mathematical study of the Force. They hope to discover a unified Force theory, allowing them to fuse the power of the Force with their technology to create unspeakably powerful weapons. The station already houses a product of this research, a terrible weapon capable of directing a coherent beam of pure Force energy¹, strong enough to destroy all life on an entire planet. This weapon has earned the station the nickname of "Death Star".

[1]As it has not yet been discovered a way for machines to directly generate Force energy, it must be supplied by a powerful Force user. The user conjures the energy inside of a specially designed resonance chamber which amplifies the energy before directing it through a series of lenses to produce a powerful coherent beam of unimaginably destructive energy.
