Time Lords HQ
The Time Lords were the semi-secret society of magi and priests that was given the task of regulating and running time in a way so as to keep balance in the world.  Due to a need for mastery of incredibly powerful magic, there were only about 50 Time Lords ever initiated.  None of these magi died of old age (a perk of being a Time Lord), although, by the time of the New World, only the head of the clan, The Time Master, was left alive.  All the others had been either hunted down and killed for their secrets by the Great Witches, or killed in the Council of Power’s Civil War near the end of the Old World.
