Time-active

A time-active civilization or power was one which has mastered time travel and its paradoxes. These are apparently not common in the universe, not least 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!)

Examples of Time-active civilizations, cultures and powers

 * The Gallifreyan civilisation - in particular, the Time Lords - were one of the most signficant temporal powers.
 * The Faction Paradox, a time active organisation which revels in a paradox, they can also be seen in some fashions as a temporal terrorist organisation.
 * The Daleks, starting with The Chase, leading up to the Last Great Time War. Surviving Daleks now retain the ability to manage "emergency temporal shifts." (DW: Doomsday, Evolution of the Daleks)
 * The Monan Host, while not on par with the Time Lords, possessed powerful temporal ships.
 * The Enemy were another power, opposed to the Time Lords.
