When two envoys from the Sovereign`s Finest disappear on a critical mission, an unlikely band of allies, led by Soot, a rhy-crow with dark and secret power, are brought together to combat a hidden threat. As portents bloom across the smuggler`s den known as Serpent`s Haven, these strange agents quickly find themselves tested by the machinations of a cult dedicated to darkest Shadow. Grieving, afraid, and unsure who to trust or where to turn, they must rely on one another and their erstwhile allies in hopes of rescuing the envoys and foiling a terrible plot. Success will bring no great reward, but failure is unimaginable. Can they overcome their suspicion and fear to fulfill their mission, or will they, too, fall to Shadow?
