Hindrance is a dimension between the world of the living and the world of death. People who entered the Hindrance were either their lives were hanged between life and death or were deceived by dark occult users. Skillful invokers usually used this opportunity to take people's souls. Controlling Specters in their command, they killed people who lost in the Hindrance and collected their souls. A bunch of survivors was dragged into the Hindrance, and it is now a survival game. Join the survivors and overcome the invoker’s puppet or return to the realm of the living by escaping the Hindrance, or be the Specter and hunt and collect souls.
