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 beyond the boundary of life as a guest. However, with the invention of thanatonautics, everything changes. A few brave souls have invented a way to travel on the edge of shadows, which has led to unpredictable consequences – after all, each confession wants to prove its correctness and colonize the afterlife.
