Coldtowns are enclosed areas in a fictional world where vampires and humans coexist, often depicted in literature and media. These towns are designed to contain and isolate vampires, allowing them to live freely while keeping the rest of the population safe. Humans can enter Coldtowns, but they risk becoming infected with vampirism. In these settings, the rules of society change dramatically. Coldtowns often have their own cultures, economies, and social structures, with humans and vampires interacting in complex ways. The concept explores themes of isolation, desire, and the consequences of living in a world where the line between predator and prey is blurred.
