Levithian
From Tardis Wiki, the free Doctor Who reference
Levithians were a species of Near-Humans from Levithian. They were a member of the Cyrrhenic Empire and were led by an Emperor.
During the frontier wars, the emperor Graff Vynda-K left the throne and fought in the war, allowing his half-brother to come in and take power. Following this, Graff Vynda-K went in search of a planet where he could create an army to take back his planet. (DW: The Ribos Operation)
