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.
The Dread Masters, who broke away from the Sith Empire during the Galactic War, were drawn to Oricon due to the dark energies left over by Darth Vitus, and set up their base of operations on the desolate moon. The Empire and their enemies, the Galactic Republic, would attack Oricon and destroy the Dread Masters all except one who lived on.
