Dromund Kaas, a planet, was once considered a mere legend, alongside Moraband. During Darth Sidious's time as the Dark Lord of the Sith, Beaumont Kin, a historian, theorized that he journeyed to this planet in pursuit of Sith relics. This theory was based on discoveries by the Exegol Excavation Project on Exegol, a planet under Sith control. Kin referenced Dromund Kaas in his book, The Rise and Fall of the Galactic Empire, which was published in 35 ABY.
Within established Star Wars canon, Dromund Kaas is noted in the reference book Star Wars: The Rise and Fall of the Galactic Empire (2024), authored by Dr. Chris Kempshall. This world initially appeared within the Star Wars Legends timeline. Its debut was in Star Wars: Jedi Knight: Mysteries of the Sith, the 1998 add-on to the 1997 video game Star Wars: Jedi Knight: Dark Forces II.
