Tholians were one of many species previously portrayed by the holovid actor Palleus Chuff prior to 20 BBY. The actor seemed to hold having played the species in high regard though why that was is unknown. Little is known about the Tholians, their culture, or even what they looked like. Considering Chuff's short stature, they were probably a diminuitive race if Chuff effectively portrayed one of them. They presumably originated from the Tholian system in the Meram sector of the Outer Rim Territories.
