A darkness is stirring in the Kingdom of Solenis. Bandits roam the open fields while mysterious figures work to undermine the cities from within. But in one small town in the middle of nowhere, a band of unlikely heroes rise to face the shadows.
One year after the events of Harmonics, Scootaloo, Thistleroot, and Mimic return to Greenhaven Grotto. Within the long sealed ruins of Libiris, ancient spirits vie for power and ancient grudges rise anew.
