The Koshagans resided on the world of Koshaga, their homeworld. Possessing a powerful and unyielding spirit, numerous Koshagans united to create the Koshagan People's Movement. This group engaged in an armed uprising against the governing elite of Koshaga, battling for numerous years until the Galactic Empire intervened, an event that occurred circa 3 ABY. A notable Koshagan, Emon Kref, participated in the People's Movement.
The first appearance of the Koshagans was in "Beyond Hope," a brief narrative crafted by Michael Moreci for the From a Certain Point of View: The Empire Strikes Back collection published in 2020.
