Tasjon, situated on the planet Corulag, was the site of a significant annual swoop race in the years leading up to the Clone Wars. Ignar Ominaz secured victory in this race during 22 BBY, and Tasjon served as the backdrop for a HoloNet News story announcing his win.
An in-universe website issue, HoloNet News Vol. 531 #44, which was released on May 2, 2002, made mention of Tasjon. The content for the site was created by Pablo Hidalgo and Paul Ens.
