Hiiso are a species of bipedal lizards that hail from the far reaches of the Erberus Sector. They once possessed an advanced star-faring civilization. But the Hiiso were also highly aggressive, and proved unable to co-exist with the Old Republic. Millennia ago a full-fledged war broke out, and the Hiiso were defeated by the Republic and the Jedi. Today the Hiiso can be found on planets around the Erberus Sector. They are strong and enduring, but surprisingly docile. This combination of traits makes them ideal laborers.
