Caelum is the first part of a trilogy called "Ted's trilogy". In "Ted's trilogy" we get into the skin of Ted, a middle-aged man discovering who he is and what has happened. The world in which develops caelum is not a normal world. It is a dark and empty world, made only of fragments of reality that appear to have survived a huge cataclysm. In caelum each of our choices will mark our destiny, creating a variety of different endings. Only a few will lead us to discover what is happening.
No one and nothing can survive outside light. Nothing exists in the dark. Darkness is silence and death.

All in Caelum is light and everything to escape the light will cease to exist. In the strange world of Caelum all that mark the limits to which we can explore is the darkness.
This law applies to all residents of Caelum, included Ted and monsters. The only way for Ted to eliminate the threat of the monsters is to take them into the darkness.
