Lords of Althrace

The Lords of Althrace were considered to be fellow "Higher Evolutionaries" by the Matrix Lords of Gallifrey. They were alerted to Melanicus' escape by Rassilon, and sent Dakon Theka and the Thane of Kordar as their representatives to the council that was called to discuss ending his menace. Later they co-ordinated the stopping of time using the combined mental exertions of all the High Evolutionaries, which allowed the Doctor and his companions to locate the stolen Event Synthesizer and defeat Melanicus.
