Ko
The "tribe" of Ko is, of the orcish tribes associated with Wyrmhold, the least assimilated. Living in the northern forests, they serve as the buffer between the "civilized" folk and the "wild" tribes (whether orcish or ihmisi). They live in much the way that their ancestors did since the Cataclysm--hunting, gathering, finding treasures in the ruins of the old Free State cities that dot the forest. They are led by shamans and war-leaders.
Politically, they're neutral, although growing numbers of the younger folks are either renouncing their tribal affiliations or joining the Blood of Heroes. They look at Tabar as at glory-hounds who have sold out, despise Kard as being "soft" and "settled", and are somewhat in awe of Skem. In fact, it's only the tie to the shamans of Skem that keeps them nominally affiliated with Wyrmhold.
