Cretzin is a desolate, inhospitable world located in an unnamed system within the boundaries of the Al'sten Nebula. The furious electrical activity within the nebula makes Cretzin very difficult to locate, and dangerous to visit.
Prior to the start of the Shyedarian Revolution, Empress Htomari fled the Imperial Capitol with her followers and established a hidden base beneath the surface of Cretzin. This grew into the principle administrative headquarters of the Rebellion, and was never found by Imperial forces.
Now that the Revolution has ended, the base on Cretzin has been reduced to a remote listening post with minimal staff.
