Omega was a stellar engineer and a member of the High Council on Gallifrey who developed the Hand of Omega, a remote stellar manipulator which could be used to control the reactions within a star.[3] Using the Hand, Omega performed adjustments on a star near Gallifrey's in an attempt to provide a power source for the time travel experiments he conducted with Rassilon. However, Omega was thought to have been killed in the resulting supernova, which then collapsed into a black hole.
