Agrav is mentioned only once in the series and appears in the Invaders.
Agrav is Petrac's second in command at the beach side gate. He is a capable leader and a brave fighter as shown when he took on Thorn when he witnessed Petrac being seriously out classed by Thorn during the duel. When Petrac is killed he fights Thorn and puts up a large fight and the duel gets to the critical point. Lydia witnesses this. He is then killed by one of Lydia's darts.
