In the lands of Eltrimera, bestias have long struck terror into the hearts of humans and wizards, far before the Great War that pushed them to the brink of extinction. In the shadows of this fragile peace—preserved in blood—valiant warriors known as legionnaires are dedicated to the perilous mission of hunting down the remnants of the bestias while safeguarding both the human and wizard races. When his friend is mysteriously killed in the Terrun Forest, Leon abandons his peaceful hometown to seek vengeance. With nothing left to lose, he resolves to pursue his lifelong dream: joining the legendary Legion—an elite warrior unit that recruits only the most exceptional. Yet dreams are one thing, but the reality of Leon's upbringing in Terrun, a place where magic is scorned, leaves him uncertain about whether he possesses the qualities necessary to pass the grueling Legion entrance exam—trials that other young men and women have spent their entire lives preparing for. As Leon leaves his home, he remains blissfully unaware that he is embarking on a journey fraught with long-buried truths and dark secrets, patiently waiting to be unveiled.
