Reborn in a world where magic and technology collide, Sylvan and his brother Erian are given a simple mission by the God of Nature: spread nature. The method doesn't matter. Sylvan gets a special skill: Treeify. With it he can complete his mission. Turn the dead into trees, turn the living into tree-servants.
Sylvan's naivety shattered when he first met the humans. Erian gets killed by an adventurer group, turning an interesting reincarnation into a fight for survival, for revenge.
With the fire of a phoenix and the shadow of a siren by his side, Sylvan will carve a path through the chaos. His own path, marked by blood, of humans, of monsters and maybe even gods.
