The Angor system was located near both the planet Dantooine and the Sinsang system, all within the expanse of the Outer Rim Territories.
The initial mention of the Angor system within current Star Wars canon occurred in the thirty-seventh issue of De Agostini's magazine series, Star Wars: Build the Millennium Falcon, which was released around September 16, 2015. Conversely, in the Star Wars Legends timeline, the Angor system made its debut in Vector Prime, a 1999 novel penned by R. A. Salvatore and the initial book of the Star Wars: The New Jedi Order series.
