Tanatonauts. Verber B.

Death. The point of no return, which forces living to feel confusion and fear. From there, no one has yet returned there, behind the facet of life, no one has yet been to the quality of the guest. However, with the invention of Tanatonautics, everything is changing. Several daredevils invented a way to travel along the edge of the shadows, and this entailed unpredictable consequences - after all, each faith wants to prove its rightness and colonize the afterlife.
