The Beginning of the Sentinal (Stopped)

What happens to a man who has fallen in to a place, what some who live in Hell, call Hell? What happens to a man who has once died, but has lived again? What happens to a man who is not simply a man? This is a story of a child who has fallen in to the darkest dungeon in the most dangerous lands on the planet.

I have taken different aspects from different stories including Re:Monster, Shinka no Mi, Halo (:D), Arifureta, and some others. I used various sources from the internet to find different creatures as well as some games. Please offer suggestions as this is my first novel and most likely won\'t be the best. P.S my grammar is pretty bad so if you catch anything, please tell me since I will be mostly using word to fix them. :D

Might add/delete some tags as i go along if i think of an idea that i like.
