Skrant
Skrant was a Sontaran sent on a seven year mission to undermine and conquer the planet Braktalis, whose society seems to be similar to Earth's Middle Ages.
Demimon, an astrologer and stargazer, witnessed the arrival of Skrant's ship, and seeing it as a sign, and allied with him. Although Skrant was dismissive of astrology, Demimon's predictions came true. An army of archers, calvary and foot soldiers from Garnethe attacked Skrant and his twenty new Sontaran clones. As Demimon has predicted, the archers were able to kill the newly born Sontarans one-by-one. Demimon warned Skrant of an attack from behind, but Skrant told him that the ship had only one entrance. When Skrant went to the controls to close the door, Demimon saw his daughter on the viewscreen. Fearing for her life, Demimon struck the Sontaran's probic vent and killed him. (DWM: The Outsider)
