Pergoomi's location was within the Outer Rim Territories and New Territories regions, specifically in the Albarrio sector. This sector contained the Mygeeto system, which in turn held several planets, including Pergoomi. Positioned at grid square K-5 on the Standard Galactic Grid, Pergoomi was a lifeless, rocky world with multiple moons circling it, closely orbiting the star known as Malola.
The initial mention of Pergoomi within the current Star Wars canon occurred in De Agostini's Star Wars: Build the Millennium Falcon magazine, specifically in the forty-fifth issue, which was released around November 11, 2015. Prior to this, in the Star Wars Legends timeline, the planet was initially referenced in The Essential Atlas, a reference book created by Jason Fry and Daniel Wallace and published in 2009.
