The volcanic planet of Defileron is located in orbit of an uncharted red star in the Imperial Fringe, south of the Reydovan Empire. From 2372 until 2376, it was the home base of the Separatist Confederacy, and later the remnants of the Separatist movement following the death of Artimus Devaneaux and the defeat of his forces at Reydovan Prime on March 16, 2376. It was also a common hub for pirate organizations and independent mercenaries, as well as various other criminals against the Empire. The official name for it - given by Artimus - was the Empire of Defileron. Ruled by the demented Artimus and his successor, Demon-Kieran Devaneaux, the Empire of Defileron led a war against the Reydovan Empire until it was consumed in volcanic fire on December 24, 2376.
