For as long as Nolan Crest could remember, two things have always existed... The cruelty of the knights and the monsters that spawned in the raid every forty-five days when the sky turned red.

The knights were always there to push back the monsters, but their services came at a cost—one that Nolan's family endured for far too long.

Fed up with his parents' suffering, Nolan took a stand against one of the knights, and because of that, him and his sister almost died. However, what saved him on that dire night is also the same thing that is destined to bring about the destruction of everything that Nolan holds dear.

Cursed with a dark power that will one day consume him, Nolan is given a second chance.

He's never been stronger, but with every level he gains, he feels himself becoming more and more like The Carnage Incarnate, the monstrosity he's now destined to become.

Nolan doesn't intend to succumb to the darkness, but does plan to use it to change the world.

By force.

From a nobody to a vengeful tyrant, this is The Legend of Dark Heart and how the nations came to fear his blade.
