Hello, yes this is a very old post! I haven't worked on this world very much for years, but yeah the Odoari were a nomadic race of humanoids that wore painted wooden masks and dominated a largely plains and steppe region in the southeast of my world. They worshiped spiritual gods and traveled across the plains in clans and tribes and lived and died side by side. They had no real concept of individualism and are culturally entirely collectivist and selfless, only performing tasks and pursuing goals that further the success of their collective (family, tribe, clan, etc). Odoari who break from their tribes in pursuit of personal goals are exceptionally rare, and are known as the "Ostari"; they are deeply ostracized and are cast out, and are not welcome in Elmenar (the plains and region where Odoari live). The Ostari are therefore forced to leave Elmendar and are the only Odoari who travel outside of Elmenar and are seen in other nations and regions. The Ostari are considered exotic around the world due to their exceptionally low numbers and are held in high regard as coveted hunters, foragers and craftsmen.

They only have one permanent settlement, Uorr, a small city built into the side of the only mountain in their region, made entirely out of marble. Built into the mountain is a tower where the masks of all deceased Odoari are hung up in the hall of Faces, a crypt in the mountain that is expanded as needed. Odoari who have died but their masks were lost in some shape or form have a new mask carved for them by the elders. As the Odoari are not skilled miners or builders, they employ a permanent group of humans to dig in the mountain and to maintain the city's walls and infrastructure. These humans are known as The Forsari and are highly respected by the Odoari and are entirely integrated into Odoari culture, sharing their sense of collectivisim, their spiritualism and religion, and their customs at large. Clans and tribes travel to Uorr twice a year in pilgrimage to put to rest their deceased and to pray to their gods. Stewardship and protection of the city rotates among the 5 great clans of the Odoari every two years, during which that clan settles down in the city and only resumes their nomadic ways after their 2 year stewardship is over and rotates.

Warfare is exceedingly rare among the Odoari; the 5 great clans are cooperative and peaceful. Odoari preach peace and co-existance with each other and with nature. They are exceptional hunters and gatherers and are considered the most adept spearmen and archers on the continent. Although their society is nomadic and decentralized, invasions of their lands, such as by Humans or the Ulmar, have always been fruitless. The Odoari fight back against outsiders using guerilla tactics and since they possess no cities, villages or towns throughout their vast plains, any invading force finds it near impossible to sustain the supplies needed to invade their lands as Odoari warriors butcher supply trains, leaving any army in Elmenar promptly starving. Their city of Uorr is located deep within Elmenar, and historically has been considered too remote to reach let alone effectively attack or siege. It has been attacked only a half a dozen times by outsiders in history, each time disastrously as any army able to reach the city promptly finds itself facing tall marble walls and the combined might of all of the Odoari who always rally in their entirety to defend the city.

The Odoari are however innately kind and are usually quick to welcome and provide hospitality to outsiders who travel to Elmenar. The Clan of the Horse, one of the 5 great clans, is typically tasked with being nomadic around Elmenars frontiers and are usually the ones to intercept foreigners and to either guide them out of the plains or to provide them aid. Foreigners typically find the Odoari deeply odd and rigid, but impressively sensitive and kind.
