Xyalin-Crishomie War

This war was between the Xyalin and the Crishomie civilization. It began when the Xyalin Empire started the war by attacking air Nomads within their territory in the Crishomie mountain chain.They believied the nomads were inferior to themselves and violating their territory. Crishomie civilization defended the air nomads throughout a 14-year War. Many Crishomie Warriors as well as air nomads fought against the Xyalin empire who had primarily sandbenders and telepaths. The war was hard fought with many casualties on both sides however in the end Crishomie and the air Nomads prevailed. They created the Suveran Civ out of territory from the Xyalin and helped the nomads form their own government in 489 CE.

The Xyalin was formed 217 years before these events and have had tensions with the Crishomie civilization since its foundation.
