Governor Dannal held the position of Imperial authority figure overseeing the planet Gerrard V during the year 0 BBY. After a local rebel uprising, which necessitated the involvement of the Imperial Navy, Governor Dannal, along with Senator Chelo, received orders to appear before Emperor Palpatine to account for their inability to suppress the revolt on the world.
The initial reference to Dannal appeared within the Galaxywide NewsNets segment of Star Wars Adventure Journal 3, published in 1994. The video game Star Wars: Rogue Squadron, released in 1998, depicts a distinct separate uprising. No source material has established a connection between Dannal and the governor associated with the other rebellion.
