From the publisher: "This is the first in a new series of adventures suitable for use with all fantasy role-playing systems. All the incredible detail and playability you have come to expect from Judges Guild is now available for all game systems. Four gigantic maps detail Ravenscrag Castle and the levels below, right down to each individual stone. The Guidebook covers all buildings, personalities, treasures, and monsters with far more detail than even the pickiest Judge needs."
