A sinister force lurks within, fueled by a dark past and a thirst for revenge. The price? Twelve lives for twelve sins. As officials race to put an end to the bloodshed, the shop’s deadly grip tightens, claiming innocent victims one by one. Will anyone uncover the truth before it's too late? If you crave spine-tingling horror, heart-pounding thrills, and a mystery that refuses to stay buried, this book will haunt you long after the last page.

In a world where Classes, Stats, and Levels are the everyday norm, Reivyn has a secret.He was unusually aware of his surroundings from an incredibly early age, and Skills and Stats were acquired easily. He was just the son of an ordinary village family, and nothing appeared out of the ordinary on the surface. But below the surface, dreams of another life help shape his mentality and growth. Why does he have some remembrance of a past life, and what is his purpose in this new one?“Soul of the Warrior” is what I call a Semi-Isekai LitRPG. I say “semi,” because Reivyn's past life is remembered like a dream, and very incomplete. It is still Isekai, though, as he remembers enough that it directly shapes his personality and his sense of self.The System that governs the world of “Soul of the Warrior” is a combination of modified versions from Selkie's “Beneath the Dragoneye Moons” and Kosnik4's “Magic Smithing.” I have changed enough of these Systems and combined them in a way that is unique that I'm mostly sure it's fine, but I still have requested permission to use these ideas. They have both graciously granted me permission.Winner of the April Writathon Challenge.

Once all people received Souls and incredible powers. Some were lucky enough to obtain the Soul of an ancient and powerful creature, but fate was not favorable to all.

The world began to change, and creatures evolved. But, it was not the beginning of a new era. It was the end. A couple of months later, a dark mist appeared and destroyed the world. It was a dictate of destiny from which no one could escape.

Wain Norheim was the world's best assassin and the only one who didn't get a soul. However, he was destined to gain the power to confront fate.

Escaping through a portal into another world, he unknowingly began the apocalypse. Even the world failed to expel him.
