Chasm Forge

Chasm Forge was a class A7 mining station built at some point in the far future after humanity had become a spacefaring species.

After receiving a distress call, the Twelfth Doctor went to the station with Bill and Nardole. (TV: Oxygen)

Design
Chasm Forge was built on top of an asteroid from which it mined resources. The station itself was circular and made up of several sections connected together by circular rings. The station was connected to the asteroid by a single central support column. (TV: Oxygen)

technology
Chasm Forge was designed as a mining station. Its computers were controlled by an onboard artificial intelligence called Velma. She monitored communications, the airlocks, th oxygen supply, the space suits and had many other functions.

The space suits on board Chasm Forge possessed mechanized exo-skeletons that meant they could take control and function automatically, without there necesarily being an occupant present. When put a user the exo-skeleton would wrap itself around the user's limbs and the rest of the suit would teleport onto the occupant.
