Gryffud Valaragga

Along with Lothar Von HughGraven and Werik Lezirin, Gryffud Valaragga was one of three students expelled from The Arcane Academy of Standopolis for illicit necromantic experiments.  
Later in life Valaragga became obsessed with obtaining the Star of Ruin, an artifact of incredible power.  The pursuit of this led to his mind being broken, and his ultimate defeat at the hands of Manfred Von HughGraven.
