Aguarus, Aragan
A young knight whose lands were invaded by the Count of the Valley. Agaran’s uncle, a holy man, left his hermitage to come to Agaran’s aid. The two of them defeated the Count, but the Count’s nephews subsequently slew Agaran’s uncle in his cloister.
During the Grail Quest, Lancelot visited the hermitage and saw the body. Lancelot’s host conjured a devil to explain the circumstances of the man’s death.
