Doctor Sigma

Sigma-063 was a Clockwork Cherub and the Crew of the Copper-Colored Cupids' resident inventor.

Sigma created a prototype for a sentient, self-driving Fog Ship, but shelved the project due to the Ship proving disobedient and thus more trouble than it was worth. He also built a large metal Courthouse for the Crew, only for the building to be stolen wholesale, using dark magic, by Sebastian Steer, who used it as his Imperial Castle.
