Aur IX was a spherical diamond the size of a terrestrial world. It occupied the ninth orbital position in the Colonies' Aur system. The diamond was believed to have at some point formed the core of a gas giant–type planet, and the creation of the free-floating sphere was widely attributed to members of the Celestial species, which had disappeared from the galaxy by 30,000 BBY. Aur IX, Aur X—a similar spherical object in the Aur system's tenth orbit—and the cloud of diamond fragments occupying the eleventh orbit were collectively known as the Aur Diamonds.
Behind the scenes
Aur IX was originally meant to be mentioned in the 2012 reference book The Essential Guide to Warfare by Jason Fry and Paul R. Urquhart; however, the sidebar that would have mentioned the diamond was cut before the book's release. The information regarding the object was later released in 2013 as part of Star Wars: The Essential Guide to Warfare Author's Cut, a series of articles published on the StarWars.com Blog by Fry and Del Rey editor Erich Schoeneweiss containing various cut content from The Essential Guide to Warfare.
