Evocii

"An oppressed and miserable species, the Evocii were once Hutta's sole inhabitants. They were a primitive people, existing in small tribes and possessing basic technology. Then the Hutts came, exchanging their advanced machines for Evocii land until they had bought up the entire planet." "Now the Evocii are enslaved, preserved only to serve their corpulent masters' whims. While a few brave Evocii actively oppose the Hutts' tyranny, most have resigned themselves to a life of servitude. The Evocii are generally found in small, impoverished tribes on Hutta and Nar Shaddaa, though a lucky few have managed to escape the Hutts' influence and carve a life for themselves elsewhere." ― Star Wars: The Old Republic, Evocii codex entry
