Months after the fall of the Citadel, scattered refugees find themselves trapped in the southern swamps, the home of ancient denizens that prefer to be left undisturbed. On the other side of the world, the possessed children struggle to find their place amongst the people of Derregain. But a demonic plague has already taken hold in the once great city, and the few that stand against it are under siege by servants of Plaguebringer, the demon who engineered it. Will friends and enemies, both old and new, set aside their differences and come together to fight the demon that threatens to destroy them all?
