Duros are hairless beings with blue skin and large red eyes and are said to be among the first spacefaring humanoid species, including humans. They are known for their superior astronavigational skills. Their homeworld is Duro which is in the galactic core.
The Duros haven't set foot on their world since the Empire polluted it with weapons Factories, Instead they live in large orbital cities surrounding the planet.
Duros are related to the Neimodians, the aliens in charge of the Trade Federation that existed before and during the Clone Wars. Many years before the formation of the Galactic Republic, the Duros colonized the planet Neimoidia, and thus the Neimoidians, a newer "version" of Duros, were born. The Duros consider the Neimoidians to be cowardly and take offense at being mistaken by other beings for a Neimoidian.
Duros are also known for their great story-telling skills because of the many places that they have visited during their travels throughout the galaxy.
Their home planet was remade by the Yuuzhan Vong during the war into a bio-shipyard for the vongs living creations.
