The Aturi Cluster existed within the Hook Nebula of the Outer Rim Territories'. The Alliance to Restore the Republic had established significant anti-atmospheric defense systems in that location by a time shortly following the Battle of Yavin. As part of the Hook Nebula campaign during the larger Galactic Civil War, the Galactic Empire's Qeimet fleet initiated an assault against the star cluster. During this conflict, Captain Tomax Bren commanded the fleet's Scimitar assault wing, which made use of TIE/sa tactical bombers, and they successfully employed their newly created Vertical Swoop technique. Major Arhul Hextrophon, a Rebel historian, later included the attack on the Aturi Cluster in a collection of Imperial documents for Supreme Commander Mon Mothma and other officers of the Alliance.
The Imperial Sourcebook, a 1989 publication by West End Games for Star Wars: The Roleplaying Game and written by Greg Gorden, was the first mention of the Aturi Cluster. Later, The Essential Atlas reference book from 2009 specified its location as grid square O-18.
