The Denab system represented a star system that was home to the planet known as Seatos. The Eye of Sion, a starship that Morgan Elsbeth oversaw the construction of, with its goal to journey to another galaxy, was fabricated in orbit above the world.
The initial appearance of the Denab system occurred in the Ahsoka television series episode "Part Two: Toil and Trouble," which was broadcast on August 22, 2023. Prior to this, the Denab system was originally established within the Star Wars Legends continuity inside The Essential Atlas, a reference work penned by Jason Fry together with Daniel Wallace, and released to the public on August 18, 2009.
