Speak with Zarlman Two-Moons in Bloodhoof Village.
I cannot thank you enough for cleansing my tribe's well, <name>, and for fighting the savage Grimtotem to do it. But there is more to be done, and it is time for your journey to lead you beyond Bloodhoof Village.
Zarlman Two-Moons stands by the fire in the north end of the village. Go speak with him and learn of the next ritual you must undertake.
