Dewall Paez was a Human male living on the desert planet of Tatooine during the period of the Galactic Civil War, and he also held the position of leader within the Wayfar spies. During the year 1 ABY, the Wayfar spies were hired by Bib Fortuna, who served as the majordomo of Jabba the Hutt, to conduct espionage on Romo Vax. Fortuna harbored suspicions that Vax was planning to betray Jabba's organization. However, Romo Vax successfully manipulated one of Bib Fortuna's subordinates into carrying out the assassination of Dewall Paez, as well as some other Wayfar spies.
