Though unnecessary this page was made due to special request.
The Uvoai-vokan were a bipedal ape like race who lived on the home world of the Ptranosaurians even long before the Ptranosaurians became sentient, their culture was to hunt dangerous creatures for sport. This nearly drove the non sentient ancestors of the Ptranosaurians to extinction, however when heavily endangered they Ptranosaurians became sentient and began a long bloody war for revenge against the Uvoai-vokan which lead to a war for extermination. Though the Uvoai-vokan are extinct, their language lives on, and is spoken by Ptranosaurians even today.
