|Region||St. Ancestral Mountain Range|
These are a set of ruins that are not too far from Glory City in the St. Ancestral Mountain Range. It is rumored that before the Age of Darkness, a Legend rank Demon Spiritualist lived here and that they integrated with an extremely horrifying demon spirit. After their death it was occupied by nightmare demon spirits. Only those of Black Gold rank or higher would dare to enter.
During Nie Li's absence from Glory City, Ye Ziyun, Xiao Ning’er, Lu Piao, Du Ze, Duan Jian, Wei Nan, Zhang Ming, Zhu Xiangjun, and Xiao Xue(most likely) visited this and many other places to train.
