Haidoral Prime was a planet located in the Mid Rim region of the galaxy. Everi Chalis was the Imperial governor of the planet. It was the location of a conflict between the Rebel Alliance and the Galactic Empire during the Galactic Civil War. During the battle, Twilight Company captured Chalis and took her aboard their ship, the Thunderstrike. After that Everi Chalis became a source for the Rebel Alliance.
Haidoral Prime's rain was unusual; it was described as smelling like vinegar and coated skin "like a skin of acrid sweat." The planet had at least one chain of mountains that were "crystalline" and was home to at least three continents.
