Dressellians were a species of sentient humanoids that were native to Dressel. They lived in peaceful isolation from any conflict until the Galactic Civil War. As a species, they were loyal to the Galactic Republic and after its demise many Dressellians joined the Rebel Alliance. They had hairless heads and wrinkled visages and cranium. Orrimaarko, a male Dressellian, was a soldier for the Rebel Alliance during the Galactic Civil War.

Following the dissolution of the Imperial Senate, the Rebel Alliance’s Commander-in-Chief Mon Mothma noted in a journal entry within the Rebel Files that she considered the Dressellian population, along with the Mon Cal and Sullustans to be especially vulnerable and that they should consider taking in refugees.

During the Galactic Civil War, a Dressellian resistance fighter named Lokmarcha served as a major in the Rebel Alliance. Shortly before the Battle of Endor, several other Dressellians attended the Alliance briefing during which the attack on the Galactic Empire’s second Death Star was prepared.
