Sinkhole/Legends

Utapau, an Outer Rim Planet, was covered with large, deep holes, called sinkholes. The inhabitants of Utapau were forced to live in the sinkholes because of the strong winds on the surface. The sinkholes each had different levels. Pau City was divided into ten. Each sinkhole ends with a assortment of small lakes. It was at Pau City where the Battle of Utapau took place. Because of Utapau's steep slopes, Pauns and P'auns used reptilian, bird like creatures called vractyls to travel around. In one of the Utapau sinkholes, General Grievous uses it as a base for his huge droid army, which will battle against the Republic's clone troopers.
