WotC Code:

'Aliisza and Kaanyr Vhok have returned from their attempted invasion of Menzoberranzan and set their sights on Sundabar. But before she can complete a mission inthat besieged city, Aliisza finds herself in the one place a demon would never want to go, no matter how sure she is of her wits and cunning: the very heart of Celestia.

The Empyrean Odyssey features the return of popular characters Aliisza and Kaanyr Vhok, from Thomas Reid's Insurrection, the second book in the New York Times best-selling series, R.A. Salvatore's War of the Spider Queen. Forgotten Realms fans won't want to miss this epic tale of two fiends struggling to escape the heart of a deeply troubled Celestia'
