The Orixon Nebula was a part of the Phelleem sector in the Slice portion of the Outer Rim Territories.
The Orixon Nebula had formed by 5000 BBY from the remains of the Kashi system, which had been destroyed as a result of a sudden and inexplicable supernova explosion at some point by 24,500 BBY. By 5000 BBY, the nebula was situated within the borders of Hutt Space, and it remained so at least until the Great Sith War of 3996 BBY. At some point, a derelict starship carrying a relic from the Great Hyperspace War of 5000 BBY began drifting in the Orixon Nebula.
Around 3643 BBY, an individual affiliated with one of two conflicting factions of the ongoing struggle between the Galactic Republic and the reconstituted Sith Empire learned of a distress signal being received from the vessel drifting in the nebula, which by that time members of the Hutt species had declared off-limits. The individual subsequently sent a companion to negotiate passage into the nebula for a rescue starship. After having bartered with the Hutts for salvage rights, the companion boarded the ancient ship and discovered the relic.
The Orixon Nebula was first mentioned in the 2009 reference book The Essential Atlas, authored by Daniel Wallace and Jason Fry, which placed it in grid square S-7. The nebula was later mentioned in a Diplomacy Crew Skill mission of the 2011 BioWare video game Star Wars: The Old Republic, although the information on that mission's outcome was eventually removed from the game.
