Worra, a creature of the womp rat species, existed in the era of the Galactic Civil War, a conflict that pitted the Alliance to Restore the Republic against the Galactic Empire. Before the significant Battle of Yavin took place, Worra was kept as a pet by Boelo, a Human male who served as a henchman for Jabba the Hutt, a notorious crime lord.
The initial reference to Worra appeared within the backstory information presented on the Boelo character card. This card was part of the 1998 Special Edition Limited expansion set for Decipher's Star Wars Customizable Card Game.
