Time-active

A time-active civilisation or power was one which has mastered time travel and its paradoxes. These were apparently not common in the universe, in no small part due to the intervention of the Time Lords, who did not look kindly upon potential rivals. (DW: The Time Warrior, The Two Doctors, NA: Sky Pirates!)
