Mechanistrian

Biology
The Mechanistrians are descended from the Korad. The highest honor for a Mechanistrian is to have their brain removed and used to control the machinery on their planet. Once added to a machine they receive the knowledge of all of the other connected brains and they receive a form of immortality.

Technology
As rulers of a whole planet of machines, it is assumed to be advanced, and is at least advanced enough to carry out the transplant of their brains into machines.

History
The Korad were the original race on the world known as Korad. As technology became more advanced, a group broke off from the Korads and became the Mechanistrians. The Mechanistrians developed the technology to use their brains to control the machines and held the Korad subservient and forced them to work as mechanics on the machines of the newly renamed Mechanistria.
