Seer Tanapi:
The goblin grave robbers were working at the behest of the Ragna tribe. The spirits of the wind whispered this into my ear. I don't have any information other than that the Chief or the Seer of the Ragna tribe has the scepter.
They are trying to conjure the spirit of the leader of the Tantos tribe. In fact, at this very moment, they are performing the ceremony somewhere on the Immortal Plateau. You must find them, stop the ceremony, and get back the scepter! Hurry!
