Deen Voorson was a technician within the Rebel Alliance, a male Human who aided in the escape from Hoth and maintained a friendship with Voren Na'al. As part of his duties on Hoth, he was among the technicians responsible for adapting the T-47 airspeeders for the planet's frigid environment. After his return to Kuat, he requested that his aunt, Nell Voorson, permit him and the Rebel Alliance to take power generators, a request she denied. Upon discovering that arrangements had been made for the Rebellion to seize the generators, he initially thought his aunt had reconsidered her stance; however, he was astonished to learn that his nine-year-old cousin, Shannon Voorson, had masterminded the operation, subsequently joining him and Boo Rawl in defecting to the Rebel Alliance.
