Thanatonauts

Death. A point of no return that makes the living feel confusion and fear. No one has ever returned from there, and no one has ever been there as a guest beyond the boundary of life. However, with the invention of thanatonautics, everything is changing. A few daredevils have invented a way to travel along the edge of shadows, which has led to unpredictable consequences – because each faith wishes to prove its correctness and colonize the afterlife.
