Among the Kellid, kids have to be strong. Unfortunately, Yartak was not.
His family was notorious for having orc ancestors among them - not that that made them super popular, but they were though, good warriors. Yartak was weak, and so he realised he had inherited the worst of both parts.
One day, though, he discovered his powers. He had indeed some orc blood, but not that of a warrior; instead, he had the blood of a shaman.
Still, his people were not impressed - Kellids are not too keen on magic users. He left his home and tried to earn his life with his gifts, and so he joined a mercenary group called the Orchestra. They were fellow Kellids, but they didn't look down on him. He felt one of the lot. Only thing is they work for the Hold of Belkzen, a place he doesn't really like - but for now that's all he's got.
Recently, they've been sent to Kenabres and, if you ask Yartak, that's the best thing that could happen. He doesn't trust Ardax and he doesn't give a damn about the crusaders, but he certainly enjoys fighting demons.
For once he feels happy, feeling what he's doing is worth something, specially if that dirty orc keeps his words and helps them liberate Raliscrad.
