Xerton Nine was an astronomical object that occupied the ninth orbital position within the Xerton system of Wild Space. The Braxant Run hyperlane linked the Xerton system to the Qonto system. At some point following the Battle of Endor that occurred in 4 ABY, the Grand Magnus was a title held by an individual from Xerton Nine.
In a scandoc outlining mercenary tactics that was released around that time, the former New Republic military colonel Andrephan Stormcaller mentioned that a mercenary using proper forged documentation, especially one produced by an ID processor, could impersonate anyone, from an Imperial customs inspector to the Grand Magnus from Xerton Nine.
Behind the scenes
Xerton Nine was first mentioned in "Blasters for Hire," a 1994 Star Wars: The Roleplaying Game source article written by Anthony P. Russo and published in Star Wars Adventure Journal 3. The 2009 reference book The Essential Atlas placed the Xerton system, and therefore Xerton Nine, in grid square J-3.
