Deneba was a planet that served as the location of a temple, which was known to Cohmac Vitus, a former Jedi Master. After Tibbs Ospe, a scout of the Commerce Guild, located the planet of Vandor, he came to the conclusion that it could be a convenient stop for traders journeying in the direction of both Deneba and Manda. By the year 10 BBY, Ospe had repaired the dilapidated headquarters of the Ypsobay Trading Company and began advertising the availability of fuel and food at Fort Ypso for traveling merchants. Sometime later, Tivoche Bilure, a bartender, heard Ospe's story concerning Vandor and documented it in his journal.
The first mention of Deneba in canon was in Solo: A Star Wars Story: Tales from Vandor, a replica journal from 2018 penned by Jason Fry. The first appearance of Deneba was in the Star Wars Legends comic titled Tales of the Jedi – Dark Lords of the Sith 3, which was written by Tom Veitch along with Kevin J. Anderson, with pencils by Chris Gossett, and published by Dark Horse Comics on December 1, 1994.
