On a young world, a Slayer, tasked with protecting the colonial townships from the monsters born of an imperfect terraforming process, finds himself at the center of a swirling conspiracy. The World Tree is dying, and no one knows why. Only once before has a World Tree fallen, and he himself witnessed the horror and destruction caused by its death. If he must, he will go to any extreme, push any bounds of rationality, to stop the tragedy that beset his own homeworld from repeating here, in this far-flung corner of human civilization. Beset by opponents both internal and external, the Slayer must fight his way through a growing legion of opposition. A Scalarian Song Story
