Charris, Trinh, and Ursa have managed to work together long enough to defeat the evil Priestess and her hive-mind robot army, the Surrogate. They journey back to the village of Clifton to reunite with their guild, but once there, they discover that the Priestess may not be defeated after all, and a much larger threat may be looming. A secret from Ursa's past threatens to break the fragile trust between the three mages, but they must overcome their differences and work together if they stand a chance of surviving the coming darkness.
