Willie Ville was a large ville is located in the Carolina's.
It was the centre of Baron Willie Elijah's little empire. He used mutants as slave labour, or they are kept in his extensive zoo. The ville stopped anyone from going through, with travelers being taxed 10% of all their goods. The centre of the ville, where Willie lived, was a twenty-five story predark hotel. He ran his empire and met with his subjects from it. The elevators were run by slaves in the basement of the building.
The baron, Wille, was a large man, who used his daughters to breed, and then his Grand daughters. He was responsible for uniting the Eastern baronies during the second mutant uprising nearly two decades before. He was shot to death by his own wife/grand daughter when he refused to kill her so the Stickies wouldn't get her. (Skydark novel
