Purgatorio
The Great Sea Of Sand
Can be home to characters.
Due to the original restrictions on both nearby towns, the populations of both suffered a certain amount of boredom. Over time, enterprising Dextroluma saw a need, and so first one restaurant sprang up, then a store to sell fun books, and it simply bloomed from there. At this point, it has eclipsed the two towns in scale and size, but it has stayed a welcoming place for all the residents of both. Just... don't go too close to the gates to Los Diabolos - unauthorized visitors seem to be magically launched into the air by its defenses.
The city, additionally, is home to the royal palace of Queen Kebechet. Her palace sprawls near the edge of the Moccasin River, resplendent beneath the sun.
