In a world beyond the reach of humans live the monstrous Melkai. Five hundred years ago, these powerful beings were banished from the human world, only welcome back when called and controlled by a human. But the spell that holds them back is weakening. Melkai are slipping through the barrier uncalled. In order to restore the barrier, Nathan embarks on a quest to find the missing piece of an ancient and powerful artifact. Nathan’s own Melkai protects him as he travels the land filled with roaming monsters, but escaped Melkai are not the only threat he faces. An enemy kingdom is in possession of the missing piece of the artifact, and they are more than willing to let Nathan’s people be overrun by Melkai rather than give up their power.
