Prior to its featured appearance in the series, Mapuzo is a world that was only given fleeting mention in the 1995 roleplaying game supplement Alliance Intelligence Reports, published by West End Games.

Obi-Wan finds evidence that fan-favorite Jedi Quinlan Vos survived Order 66. Quinlan first appeared in the Star Wars Republic series from Dark Horse Comics, and made the jump from the page to a mention by Kenobi in Star Wars: Revenge of the Sith. He then appeared in the Star Wars: The Clone Wars animated series (Kenobi and Vos memorably teamed up in the Season 3 episode, “The Hunt for Ziro”) and would play a large role in the novel Star Wars: Dark Disciple.

Among the names carved into the walls of the Mapuzo safehouse are references to Jedi survivors from older Star Wars Legends publishing and video games: Djinn Altis, Roganda Ismaren, and Nichos Marr are from the 1995 novel Star Wars: Children of the Jedi. Valin Halcyon is from the backstory of the X-Wing novel series and spin-offs. Ekria, Zonder, and Drake Lo’gaan were from a series of online exclusive webstrips starting from 2004. Tiberus Anderlock is from the Star Wars Galaxies video game, Qu Rahn from Star Wars: Jedi Knight: Dark Forces II, Rahm Kota from Star Wars: The Force Unleashed, and Cere Junda from Star Wars Jedi: Fallen Order. Fable Astin and Corwin Shelvay were from roleplaying games released in the 1990s.

There are also a variety of Jedi and Force phrase, axioms, and mantras on the walls, including the High Republic call of “For Life and Light” from the series of books set during the prime of the Jedi Order.

The oceanic headquarters of the Inquisitors was developed and extensively explored as a setting for the Star Wars Jedi: Fallen Order videogame released in 2019. Players of the game would have faced similar situations as Obi-Wan does in Part IV.

The crystals mined on Mapuzo are said to be vintrium, a valuable substance that has appeared in Star Wars roleplaying and video games of the past.
