Haval

Haval was sergeant-of-arms to Lord Geoffrey de Beauvain during the Crusades. Lord Waldean de Beauvain had Haval put in the castle's dungeon after usurping Geoffrey. When the Third Doctor was also imprisoned, he and Haval escaped but were re-imprisoned in Signus's quarters, where Geoffrey was being held in a trance. After the lord was revived, the Doctor constructed a glider to allow Haval to fly from their tower prison and over the moat. Having escaped, Haval fled to retrieve help from the King. He was caught by Waldean's men, but was saved by the King's timely arrival, and led the King's men in recapturing the castle from Waldean. (TVC: The Magician)
