Jyrues Vanoch is a Cultist of Vecna, said to be able to rival Zuud.
Quite little to no information has ever been collected about Jyrues, except for the fact he is a Cultist of Vecna from the Sabbra-Caddabra regions. It has also been said he was born to noblity, and that his father was a womanizer.
Jyrues met the party after he and Zuud kidnapped Hrafn. He engaged them in combat and was defeated. He apperently killed himself by activating over three hundred hidden blast patches in the room.
Some time later, the Party again encountered Jyrues after taking back their castle.
