The Sullustan are a race of small, mouse-like humanoids can be distinguished by their huge almond-shaped black eyes, loose jowls called "dewflaps", and pointed ears. Their skin colour is usually pink, but some are grey or light green. They salivate quite often and live underground to avoid Sullust's inhospitable atmosphere. Their ingenuity and adaptability have allowed them to create huge underground cities, and their technology has grown at an incredibly fast rate.
Humanoids, Sullustans can see up to 20 metres in the dark and have an incredible sense of direction, having lived in caves all their lives. Additionally they are known to have the uncanny ability to remember a path or map exactly, even after the first time they see it. Thus, many Sullustans have become pilots and navigators.
Unfortunately, due to the evolution of the species in a low-light or completely dark environment, they are genetically predisposed to corneal defects at around the age of 30 years or so; many choose to wear special visors to prevent further damage when this condition manifests itself.
