A group of disparate heroes have been brought together to decide the fate of the city of Neverwinter. This is a tale of battle and intrigue. The heroes must learn who they can trust as they stir events that will bring the city to a turning point. Who is the new Lord Protector of Neverwinter? Are the tales of deception, corruption, and assassination true? As for the rebels that toil against the Lord Protector, who is their leader, she who seems to have entered the stage from nowhere? Only the heroes, caught in this roiling sea of masked truths, can put things to rest in Neverwinter.
