Prisoners of the Left Order

Sunlight is a deadly poison, and darkness is the refuge of mankind. In the deepest part of the earth, on a throne of white bones, the ancestor who had been sitting for nine thousand years slowly opened his eyes. The person he had been waiting for had finally arrived. In the underground city where darkness and order intersect, the young man walks with a stick. He just wants to recover the blood debt for his grandmother who died tragically. When the boundaries of cognition are broken again and again, when good and evil are no longer clear, who is not a prisoner? Where is it not a prison?
