Monsters lurk in the night, but what if something else hunted them? An incident in his childhood left Velik an outcast with a racial subtype that thrives at night and unique class called [The Black Fang], which focuses on just one thing: killing monsters. He’s good at finding them, and he’s good at slaying them. For ten years, he’s been gaining levels and sharpening his skills on the thousands of monsters infesting the wild lands of the frontier. For ten years, he’s kept a lonely stretch of towns safe. Despite his efforts, this year has seen an explosion in the monster population, so much that he’s no longer capable of protecting everyone by himself. This draws the interest of another monster hunter, one that’s professionally licensed, but he seems more interested in investigating Velik than anything else. At least with him there, Velik is free to finally explore the mysteries of the deep wood, where he believes the source of all monsters resides. Every answer he finds leads to new questions, and not even Velik himself knows the truth of what happened on that fateful day. One thing’s for sure: not even the monsters are safe in the dark.
