This is a huge laboratory secretly built underground in the city! This is a world completely isolated from the outside world. There is no sunlight here all year round, and the people imprisoned here cannot escape the darkness for their entire lives. This is the Auburn Laboratory, which specializes in adopting, studying and training "monsters" who are feared, rejected and despised by humans. The purpose of the Auburn Laboratory is to make this group of "monsters" available to them, and to create more "monsters" like them by studying their DNA.
