Grom has<em>quite</em>a large following, actually. Adventurers worship him almost by default, because lets face it - he's the god of killing people and taking their stuff. Warriors of every stripe venerate him, especially gladiators who fight for their lives on a daily basis. It's worth noting that Grom was the first Saint ever, and he earned his godhood by killing off a bunch of other deities, unlike the others who were born with deific power. The Berserkers are noteworthy as the only people who openly admit to following Grom, and the berserkers even have a patron saint of their very own - Kornan the Invader, patron saint of Rage.
