Kosmimia, sometimes called the Kingdom of Kosmimia, is a kingdom populated primarily by Avolix. It is a parliamentary democracy and a constitutional monarchy, and it is located in the Western mountain range of Graennarune, primarily by the Zaferi and Roumpi Rivers west of where they merge, and in the immediately surrounding mountains to the north and south. Kosmimia is the only large avolix state, as all other known avolix live in small villages scattered around the continent.

The Kosmimian flag's design represents a simplified form of the river fork where the original capital was located, plus a gemstone to represent how Kosmimian avolix do their magic. At the time the first iteration of the flag was created, maps made by Kosmimian avolix had south at the top and north at the bottom, which helps in understanding the design choice.
