From the back of the book:
Destruction. Death. War. Magic. The Night Kings are more than simply Izrador's lieutenants and tools. They are avatars of his darkest aspects, and they are the unwelcome demigods of Eredane. Opposing them all is one being, Aradil, the Witch Queen. Both more and less than mortal, she is a monarch of life, light, passion, and defiance. She alone stands like a mighty tree against the tides of darkness.
This resource is useful for any MIDNIGHT campaign, whether an epic-level odyssey in which the Night Kings or Aradil are met face-to-face or a newly begun journey in which their machinations are felt just beneath the surface. Delve into their minds and strongholds, learn their hidden pasts and their darkest dreams, and discover the true power of the Legends of Shadow.
Legends of Shadow includes:
Official stats for the Night Kings and Aradil using epic-level rules.
Background information for each of these powerful figures, including goals, histories, resources, and weaknesses.
Insight into the Night Kings' secret wars with one another, with Aradil, and in some cases with themselves!
