The Valltii represented a sentient species that originated on the planet known as Vallt. Their physical characteristics included a stocky build, expansive and circular faces, and mouths specifically adapted for consuming meat. They also possessed ice-[blue](/article/color] colored skin and a thick, shiny growth of facial hair. Galen Erso noted their proficiency as stoneworkers. Certain Valltii served as military personnel, riding taqwa as Valltii riders.
