Head Blacksmith Lombert:
I know this will be a challenge, but won't it be worth it? If you gain the trust of the tribe and become their true friend, you should be able to obtain the Divine Stone of Wisdom. In the instance of Ketra Orcs, visit the Ketra Messenger, Wakan, at Ketra Orc village. For the Varka Silenos, visit the Varka messenge, Naran Ashanuk, at the Varka Silenos village.
