What happens when the hero stops believing? Sylven carries the weight of humanity reduced to ruins. He is the strongest, the most skilled… and also the most lost. In a world where faith is deadlier than any blade, and demons walk disguised as allies, the real war isn’t fought against monsters. It is fought within oneself. There are no chosen ones here. No prophecies, no gifts bestowed by fate. Only men and women who bleed, who doubt… and still keep fighting. Five kingdoms cling to a fragile peace as forgotten secrets and blessed weapons begin to awaken. Surrounded by betrayal, conflict, and moral wounds that cut deeper than steel, Sylven must decide what kind of man he wants to become… before the world collapses again. But he is not alone. Suo, a young swordsman with an assassin’s heritage and a hero’s dream… Ari, a brave mercenary with a past that burns… And Lila, whose tenderness persists even in the heart of chaos. They will not only fight beside Sylven… They will make him see the world differently, saving him from becoming something terrible. Amid the mysteries of the Poly-Masters, the divine whispers of the weapons, and the echo of a war that never truly ended, Aeviternus is not the tale of a hero’s rise, but the breaking of one who refuses to be seen as others see him.
