[edit] History

A colony of Purebloods were convinced by the Rutan Host that their kind had abandoned them and had plans on subjugating them. Angered, this colony of Purebloods attempted to exterminate their clone descendants until the Doctor showed them that they were only being used by the Rutans who planned to kill the remaining Purebloods once they had accomplished their goal.
