Behind the scenesEdit
Exar Kun was first mentioned in the new Star Wars canon in Gadgets and Gear, a 2019 supplement to the Star Wars roleplaying products made by Fantasy Flight Games. The character was created by Kevin J. Anderson and originated in the Star Wars Legends continuity, where he first appeared, albeit unnamed, in the 1994 novel Jedi Search before being fully introduced in the sequel released that same year, Dark Apprentice. When creating the character, Anderson was initially unsure whether Kun should be a Dark Lord of the Sith or a "Dark Jedi," finally making his decision when George Lucas voted on the former.
In the 2018 reference book The Art of Solo: A Star Wars Story, Solo: A Star Wars Story set decorator Lee Sandales describes the obsidian stone used as the base for crime lord Dryden Vos's desk aboard the First Light as having been plundered by Vos from the Sith temple of Exar Kun, although no in-universe source has yet confirmed this.
