Ómnurrir refers to both the land area west and south of Gnial, especially that area closest to Gnial, Yócnath, and the people living there. The area was settled sometime before 100 AA, as the initial human settlers peacefully divided Gnial and Ómnurrir between them. The term is considered somewhat derogatory; their own name for themselves is Obéosožiras, the people of spirit.

The Ómnurrir have very little in the way of organized, large-scale government, or indeed permanent cities, instead living in widely-scattered homesteads which contain 2-300 individuals. Each homestead has a rough territory upon which they hunt, fish, and farm. Despite this isolation, they frequently meet at the Fáus, the “fire festivals”, which occur every six weeks or so at the solstices, equinoxes, and the midpoints between them. Gatherings take place at the Asšónsasáec, Stonehenge-like structures that mark places of ritual, celebration, and trade.

The only large-scale government of the Ómnurrir is the Ómouámtid, a yearly gathering of all the heads of registered homesteads, at which is decided matters of trade and hunting rights and so on.

In contrast to the Iómr Mnór, the Ómnurrir have an oral culture that eschews the written word (or uódhuáld, “dead words”) and places high value on memory and storytelling skill. The Fáus are renowned for their hours of dramatic retellings of stories and epics. One of the most famous epics, recited each year at the Nlálš festival (during the longest night of the year), concerns the coming of the hero Úoar Ásárél and his battle with the Ásdhaárš, a machine capable of destroying entire planets. Another, usually told at the spring festival of Sálsšúor, the Spring Sun, is the tale of Afoébdhroiéas Nál and his journey to cast the evil ring Róeulául into a volcano.

A notable fact about these stories, and Ómnurrir beliefs in general, is that each of them is guided and helped by a small personal spirit called an ánéal. The ánéa come in three types, éaleáel, and foús. Éal spirits are driven, fiery, and goal-oriented; eáel spirits are quiet, stubborn, and conservative; and foús spirits focus on the flow of connections and interrelations between things. The Ómnurrir have adúadh, itinerant religious teachers who travel from homestead to homestead, bringing news and small assistance such as healing and ánéal renewal. The adúadh have a Council of Judges, which meets every year at the Autumn Fire Festival Alaúe, but there is not much formal organization.

While the core of the Ómnurrir culture has remained largely coastal between the Oth Sea and the Wán Sea, other Ómnurrir cultures have branched off to south and inland.
