Nephus

Katsu Nephus is no ordinary 16 year old. His life, its past sad and one to leave forgotten, leads to a bright future as he explores this magic laden world. But even with this, he possesses great strength and innate talent as he is watched upon by otherworldly beings.
And when he and his friends-Griffin, Erin, and Myra-receive a quest to explore a newly found dungeon, their futures changed drastically. This seemingly ancient dungeon, hidden within the depths of a mine, holds secrets long forgotten, secrets that the gods themselves attempted to hide.
A thrilling adventure awaits these four adventurers, their lives hanging in the balance of their difficult decisions that they are forced to make.
