Grumbar
Grumbar is the Makonde tribe's ambassador to Silva Domus. He resides in Tree Ten. He is wary of the guards' attention, and once you get past his grumpy demeanor, you discover why - he's schizophrenic. There is the face he shows to the world, and then there is the darker side he keeps hidden. He harbors resentment for the other Bok tribes, most notably the Yaka tribe.
When Ogmog approached Grumbar and asked if there was anything he could do to assist the Makonde and increase his reputation, he was at first hesitant, but then had a change of heart when he realized that Ogmog was interested in conquering. Pulling him into the back of his embassy, he presented Ogmog with a skull which functions as a communication device. Grumbar requested that Ogmog and his friends track down the Yaka shamans and take their trinkets, which would leave them powerless and seriously cripple the tribe.
