Korad

Biology
The Korad are the human mechanics of the planet Mechanistria

Technology
While the Korad work on the advanced machinery inside of Mechanistria and use some advanced tools in their work, the technology that they seem to have for personal use is fairly primitive.

History
The Korad were the original race on the world of Korad. As machines became more advanced a group broke off from the Korads and became the Mechanistrians. The Mechanistrians had long held the Korad subservient and forced them to work as mechanics and in menial tasks on the renamed world of Mechanistria.
