Branth, a manufacturing world dedicated to droids, belonged to the Galactic Republic as an industrial planet. The Galactic Empire's ascension and the New Order's insatiable need for droids led to such extreme pollution that the world became uninhabitable and had to be deserted. Being the sole planet within its system, Branth's surface was entirely obscured from view by a dense, gloomy, gray smog that permeated its atmosphere, making any landmasses indistinguishable from space. The planet's air was characterized by its intense heat and humidity, and the pervasive mist made it almost impossible to determine if there was any rain. The Empire repurposed this desolate world as a high-security penal facility known as Prison Base, with Commander deWolf in charge.
