From the depths of the demiplane of shadow comes a new magic so mysterious it confounds even the Chosen of Mystra. From beneath the dune seas of Anauroch escapes one of Toril's most powerful and ancient evils -- the phaerimm. From Evereska, the last elven refuge on comes word of invasion. From nowhere appears a group of enigmatic sorcerers determined to destroy the phaerimm and save Evereska . . . for purposes known only to themselves. From the author of Crucible: The Trial of Cyric the Mad, Beyond the High Road, and Death of the Dragon (with Ed Greenwood) comes the most Realms-shaking event since The Threat from the Sea.
