Kûniüri is a lost nation of the Ancient North and the last of the ancient Aumris empires. High Norsirai city-states developed along the River Aumris and from c. 300 were united under Cûnwerishau, the God-King of Trysë. From c. 500 the city of Ûmerau gained ascendancy, leading to the Ûmerau Empire and the cultural efflorescence of the Nonman Tutelage under Carû-Ongonean. Ancient Ûmeria thrived until defeated by the Cond tribesmen of Aulyanau the Conqueror in 917. The rapid collapse of the so-called Cond Yoke led to a second period of Trysean dominance of the Aumris, this one lasting until 1228, when another series of White Norsirai migratory invasions resulted in the so-called Scintya Yoke.
