Awakened in a dungeon by a voice calling him "Harbinger", Hyx had no recollection of his memories prior to this peculiar situation. There are only two things he remembers, his name and he comes from earth. Facing the countless aberrations of the dungeon, he came to realize he is not on earth anymore.  Now faced with such reality filled with dangerous monsters, hostile environments and difficult choices, his humanity and morals will be hanging on a thin blur line between black and white if he wishes to survive. This is a story of a seemingly normal human's transformation into a monster. A tale of a boy's rising among terrors of the foulest. An overture of a tragic and epic odyssey. A/N: This is a novel inspired by japanese light novels and web novels. Also, I'm not really good at English as it is not my first language. I am aware of the grammar mistakes and inconsistency in my writing. Please pardon me for this and by all means, point out any mistakes spotted. I will be grateful for that.
