I think Garuik belongs to a "peaceful" race like arion, the green orcs or the alurines, since usually for hostile races, like the red orcs, you meet the enemies before the NPCs, plus given that Garuik has a soothing potion in the sprite, he seems a good guy, and Ste is the only minotaur that is not affected by the corruption (other than his children) and it would be strange to meet another minotaur not affected by the illness, while we can "meet" only two corrupted minotaurs.
