An ancient castle, Nol-Daer, has of late become the site of frequent strange occurrences. Gargoyles and Blood Hawks roost in the keep's ruined towers, Dwarves have been disappearing from the nearby area, and a Cambion controls it all from the shadows.
Original adventure from Dungeon Magazine #013 is written for 2nd edition and is 15 pages with tactical maps. A stand alone PDF modified by The Cobbler for 3.5e is also available. This version is 86 pages with the same tactical maps, but also includes handouts.
This adventure doesn't have any pending change requests.
