Grath
From Tardis Wiki, the free Doctor Who reference
Grath was the brother of the emperor of the Levithian Empire. Grath made arrangements for his brother to be poisoned, killing him. Grath framed Rigel for the murder. He soon became regent for the emperor's twin children, Ella and Asher. Grath planned for the deaths of the twins in a spaceship accident, but the twins were saved by Rigel, with Grath believing them to be dead. When the children came of age, Rigel returned them to Levithia, and Grath was placed under arrest. (PROSE: The Twins in the Wood)
