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.
