The Clattering Keep

An abandoned ancestral keep is haunted by undead dragons, necromancers, and other shadowy forces drawn to a tome of dark power hidden in its library. A party of four to five 4th-level heroes explores the shadow-haunted stronghold, confronts its guardians, uncovers its secrets, and seeks to cleanse the keep.
