Border Xu Cave

There may be some unreasonable things in inspirational writing. In the medieval dark fantasy worldview, Border Market Cave is a slum town leaning on the mountains. People who grew up here made a living by buying and selling, joining the border patrol to fight monsters, and collecting various materials. The sky here is obscured by smog all year round, and the air quality is not very good. Many residents who cannot find a place to live and the outside world is too dangerous will choose to use brackets to prop up their houses on the edge of the cliff. Even if it is very dangerous, some people will choose to do so. Piwa and her family are an example.
