The town of Somber Hill is a quiet settlement in the foothills of a mountain range. A few days travel from the nearest city, the people of Somber Hill are a humble and self-reliant bunch. Unbeknownst to its people, the small town hides a sinister secret, some of the residents of Somber Hill belong to a cult that worships a long dead entity. Known only as The Dark One by their followers, this ancient being once called Old Somber Hill home. Their dark master is entombed in the catacombs beneath the town, and the cult hopes to resurrect their master with a blood sacrifice. The Crypt of Somber Hill is a Setting Neutral adventure and thus can be easily included in any existing story-line with minor alterations and adjustments or outright slotted into any existing campaign setting.
