Trevaia is one of three Priestesses slain during the Attack on Chapel Anvil when loading the Knights of the Nine plug-in. Fellow Priestess Laralthir and Primate Dumania Jirich are also killed in the attack. As soon as the content is read and available in the game, Trevaia can't be used to buy potions because she is already dead. She is replaced by Selene Duronia at the end of the Knights of the Nine questline.
