Baylagon was a place situated within the galaxy. During the early rebellion against the Galactic Empire, Senator Bail Organa sought to conceal the stealing of U-wing transports; to do so, he arranged for an Aldraig data clerk to mistakenly direct a shipment of U-wings via Baylagon, en route to Coruscant.
Following the commencement of an investigation by the Galactic Empire's Imperial Security Bureau, headed by Chief Investigator [Axvering], Senator Organa admitted the data clerk's error, but argued that a further stopover would not have posed a problem for a skilled pilot. Ultimately, the U-wing transports arrived at their destination, the Alliance to Restore the Republic.
The initial reference to Baylagon occurred in Star Wars: The Rebel Files, a canon reference book and boxed set from 2017, written by Daniel Wallace.
