Armennion Ullgusta was a director who created the holovid documentaries The Edict of Jiaan and Obeisance: Betrayal Within. These holovids detailed the destruction of the Jedi Knights by the Galactic Empire, which resulted in Ullgusta being branded an "enemy of the Empire" and his productions being prohibited. During the time of the Galactic Civil War, gossip suggested that Ullgusta often visited Pret Swain's residence in Cjaalysce'I on the planet Socorro.
The first mention of Armennion Ullgusta occurred in the 1997 sourcebook The Black Sands of Socorro by West End Games. Ullgusta was later referenced in the 2003 video game Star Wars Galaxies: An Empire Divided, a massively multiplayer online roleplaying game created by Sony Online Entertainment and released by LucasArts, before it was shut down on December 15, 2011.
