From publisher blurb:
FN11 – The Amulet of Dorian Beldor begins as a race to catch a fugitive from justice and quickly escalates into a much larger problem. With over 40 pages and 8 different maps this adventure has your party stumbling onto a former city covered by a rock slide now inhabited by a large group of humanoids. Buried deep within the complex is the ancient relic that controls elementals and will be quite useful as the Filbar North series winds down.
This adventure setting was designed for 1st/2nd Edition AD&D for the Filbar Campaign for a mid to higher level adventure group and DM. This adventure is easily adaptable to most any game and system. Save yourself some time and utilize it for a one shot adventure or a continuing campaign!
