Humans used to live here about ten years ago, but one day they just mysteriously disappeared. Nobody knows where they went... although, in present day, all of the dogs that the humans had brought with them are now running wild, and most of them take shelter in this lonely, broken down old city. It is an eerie place where death is scented everywhere. The scarceness of food and friendly faces forces many of the dogs away, and many of them insane.
