Zebulon Dak was the wealthy, influential founder and owner of Zebulon Dak Speeder Corporation during the early years of the Galactic Empire. A follower of repulsorcraft racing, Dak attended races in search of new talent and was so impressed by racer Thall Joben's performance in the Boonta Speeder Race in 15 BBY that he offered full-time jobs to both Joben and his racing partner, Jord Dusat. However, Dak was secretly involved in early resistance to the Empire, using his wealth and success as a cover for his activities, and also recruited the young racers' friend, Kea Moll, to assist in his work.
