House Tremere was one of several Houses within the Order of Hermes. It was a very powerful house, having been largely responsible for the destruction of the druidic House Diedne in the Schism War, although the actual purging of Diedne was carried out by Houses Quaesitori and Flambeau in 1012. The House was abnormally powerful given that it seemed to consist largely of sorcerers rather than true mages. Even Tremere himself was said by some to have been a sorcerer.
