The surface world has touched the boundaries of civilization and is about to perish due to the laws of the dark forest.
As a result, some people invested their consciousness into the other world. Some of them give birth to children and reproduce in the other world. Gradually, they forgot their origins.
Another small group of people have become "managers" to deal with those who have touched the boundaries of civilization. They are afraid that the world will be destroyed again.
But with the development of civilization in the other world, some people have vaguely come into contact with the truth of the world. They secretly formed an organization to explore the truth about the entire world.
Purpose: Explore the mysteries of the universe and see the world from another perspective (imagination)
