The Grass Sea is an immense steppe that stretches east of the Erithor Mountains. The sea is rumored to extend for thousands of miles before reaching the continent's eastern coast.
The Grass Sea is populated by nomadic horse tribes of a plethora of races and creeds. While many languages exist on the sea, Katachi has become the dominant trade language.
Normally the tribes of the Grass are balkanized and at each others throats constantly, however twice in the recent past, a Great Khan has arisen to unite them.
