Concept art
Concept art for "Rogue One" (2016) used Mimban as a name for the city which eventually developed into Jedha (another source of kyber), and a planet called Mimban was featured in 2018's "". Additionally, Marvel Comics' "The Rise of Kylo Ren" features Ben Solo traveling to Mimban, where he learns of the Mindsplinter—possibly the Kaiburr crystal by another name.
