The tribal lands of Massaquoit Barkeater. Nominally under the protection of the Barony of Telero.

A small number of Native Americans were transported from Earth to Lharna at approximately the same time as the same time as a prophet named the Great Peacemaker came to the Iroquois. The Great Peacemaker was a prophet with visions of political unity, but as with other cultures unity is more often found at the end of a tomahawk than the end of a prophecy. Eventually, a shaman, brave and chief named Iowaffa actually brought about this unity. Iowaffa, was a member of the Clan of the Bear, although he preached the equality of all clans and tribes. Iowaffa's tomahawk is a cherished Occopannac relic.

After the Androclysm, the Iroquois and a few other tribes from the forests of eastern America remained committed to the formation of a peaceful confederacy under Iowaffa's leadership. Soon after arriving in Lharna, Iowaffa, by then an old man, disappeared into the forests to the north on a Spirit Walk. The leaders of the Bear Clan struggled to hold the federation together in the strange new lands, but tribes and clans gradually splintered off. Rejecting the Bear clan's peaceful attempts to hold the Confederation together, a large group of former Iroquois, led by the Raven Clan attempted to seize power over all for themselves. The Raven War decimated the Iroquois and rather than unifying them, broke the confederation into a myriad of tribes, most of whom moved further south, closer to the protection of the other human peoples. The Bear Clan was nearly wiped out, although the few survivors married into the Wolf Clan.

It has been prophesized that the restoration of the Bear Clan will be the first step in the return of Iowaffa, who will reunify the tribes, and then of the Great Peacemaker who will usher in a thousand years of peace and stability.

While some Native Americans blended into Empire of Grodnus others banded together to form the Occopannac and lived at the fringes of human civilization, living from the land much as their ancestors had on Earth. Unlike other humans, the Occopannac to their knowledge are not at war with and have no problems with the elves, whom they call "spirit folk".

While most Occopannac speak the "white man's tongue" they also speak their own language, which is linguistically related to Iroquois languages. Most Occopannac worship the Great Spirit.

Occopannac live in longhouses and employ holding halls.
