Keldooine, situated on the border of Hutt Space within the Mid Rim Territories and the Slice, functioned as both a planet and a shadowport. While it served as an important world in the region during the Republic Era, piracy which was widespread in the Slice, had infiltrated Keldooine by 33 BBY. Maz Kanata, the one-time pirate Queen, identified it as a noteworthy location on a map featured in the book that would eventually be titled the Smuggler's Guide.
The planet Keldooine was initially referenced within the current Star Wars canon in Star Wars: Smuggler's Guide, a reference book from 2018 authored by Daniel Wallace. Its first appearance was in the 2024 novel, The Living Force, penned by John Jackson Miller. In Star Wars Legends continuity, Keldooine was initially brought up in The Essential Atlas, a reference book from 2009 written by Wallace together with Jason Fry.
