The shaman and its PHs all spawned from various points east of Kurn's for me, mostly in the grassy area, but they do roam out of that area, and they all seemed to path immediately upon spawning. The PHs I encountered were iksar bandits and brigands. Respawn is extremely fast, almost immediate. I found the initial shaman walking towards Trooper Drix, so it does do a fair amount of roaming.
