Prishella existed as a space object situated within both the Outer Rim Territories and the Slice, specifically at coordinates T-10 on the Standard Galactic Grid. The Pabol Sleheyron hyperspace route provided a connection between it and the celestial bodies Formos and Little Kessel.
The planet Prishella's introduction into the modern Star Wars canon happened with its brief mention in the twenty-ninth issue of the Star Wars: Build the Millennium Falcon magazine by De Agostini, released circa July 22, 2015. The planet Prishella III was initially a part of the Star Wars Legends timeline, appearing in the 1997 book Rules of Engagement: The Rebel SpecForce Handbook. This book was written by Timothy S. O'Brien for the Star Wars: The Roleplaying Game published by West End Games.
