The Tribe of Knowledge

Now that the tribes have spread out into the Mainland, no one really knows what has happenned to the Tribe of Knowledge. They have travelled farther than the Master Sages can see, and they suspect the Tribe of Knowledge lives no more. Whether they destroyed themselves in a civil war or have ventured to the very far edges of the mainland is uncertain, but either way it seems the Tribe of Knowledge has had it's impact on the world and now desires to stay silent.
