From the publisher's website:
"Over two cenuries ago, the Duke Ithinge ordered an underground complex to be built to house the Witch Head and keep it from those who would use its powers for evil. The construction of the complex was performed in a remote and secret place, its chambers and corridors filled with traps and terrors devised by his new court wizard. With the complex completed, the laborers were enchanted to never reveal its location. He knew he could not destroy the Witch Head, for it was forever linked to the vitality of his family line; its power was fueled by the evil deeds of his fore bearers, and it was written in legend that the heir who destroyed the relic would be the last of the line. The Curse of the Witch Head is designed for 4-6 characters of levels 6-10 and is compatible with 1st Edition gaming."
