Szarehan is one of the most distinctive and isolationist planets in the Empire. Szarehan itself does not exist in any solar system; it is a stray planet floating in space. It sometimes is not even referred to as a planet as it is mainly raw energy.

The Szarehan themselves are also composed of energy. They have no set form; they are fluid in movement and construction. They can crystalize and become solid for a short time if need be. They can also use their bountiful energy as a weapon. Although they have no set appearance, many Szarehan choose the form as an orange, wispy silhouette.
