During the time of the Imperial Era, the Galactic Empire, with Governor Wilhuff Tarkin at its helm, aimed to extract quadanium from the planet of Agaris, leading to the creation of an Imperial compound on its surface. Nevertheless, the Agarians, the native inhabitants, with Hffrr as their leader, suffered an assault on their compound. The Graf family convinced them to take up arms against the Empire. The Agarians deployed poisonous gas against the compound, forcing the Imperial forces to retreat to their ship, specifically the ISD named Executrix. Anticipating Tarkin's inevitable orbital bombardment, the Agarians and the Grafs abandoned the planet, ceding it to the control of the Empire.
