An insignificant world, it was once home to Darth Vitus, before its location was lost to the wider galaxy. Vitus experimented with Sith alchemy on the world, creating monsters strong with the dark side. During the age of the Great Sith War, a group of Sith tracked the world down from clues in a holocron, eventually leading them to Darth Vitus's compound.
During the era of the reconstituted Sith Empire, the Sith Emperor tasked six Sith Lords—Bestia, Tyrans, Brontes, Styrak, Calphayus, and Raptus—with studying the powerful Phobis devices, and sent them to Oricon to do so. When they emerged from their research as the mysterious and powerful Dread Masters, they declared their intention to make Oricon their home, and with the Emperor's blessing, they used thousands of slaves to construct the Dread Fortress as their citadel.
