Standing nearly a fathom and a half in height, powerfully built, with a shaven bullet-shaped head he was usually dressed in nothing more than a loincloth. He was a fighter mage who was often called dimwitted, yet he was still able to control mana and could be quite cunning. He was beaten in and out of the Arena by Garth, who quickly became friend with him.
Naru survived the Time of Troubles, having helped Garth, and became the new master of the House of Bolk.
He used especially green and red spells. He has summoned mammoths, wolves, orcs, goblins and dwarves. He gave his Juggernaut to Garth as a gift. Being a giant, he had no problem going toe-to-toe with a Frost Giant or a Craw Wurm.
