Publisher's blurb: The Countess Lucanda Hartgrave insists that Castle Antoillier is haunted. Moreover, she senses an evil growing within the ancestral estate of the Roaringthorn family. As the adventurers investigate, they discover that the unnatural terrors beneath castle are of a different, and deadlier, nature than they thought possible. Crypts of the Scions is a Halloween-themed adventure appropriate for parties of the 5th to 8th level set in the Forgotten Realms.
