Arshag was a tattooed Grolim priest, of the Temple at Calida, posing as a wizard who was able to conjure the image of Nahaz, the Demon Lord. He was associated with Harakan and had been in contact with Nahaz. Initially, Arshag had his Karandese crowd enthralled, but was debunked by Belgarath, posing as a wizard. Arshag's illusion had no substance. Belgarath summoned a very convincing illusion of The King of Hell. When Arshag tried to run, Garion stopped Arshag and then performed a wide crossing punch which felled Arshag.
