Darkness is always an excellent force. They not only make people feel insecure but sometimes even more hideous secrets. In places where the darkness envelops, and the few suns always have bad things. In the real world, the hidden corner of a lonely alley is always the place where criminals, or even perverts, kill people. In the world of gaming too, whenever you see the power of darkness begin to spread, then surely everyone will realize that crime is about to appear and to rage in the world. Then you can imagine the dark scene spreading to the ground and taking over the rule of light. Things are not proliferating but only a dead night. This is an excellent environment for evil monsters to rise to destroy all human beings including living creatures. Darkness Rises is a story like that.
