Barovia

You can run Curse of Strahd for 1st-level characters with this mini-adventure, which is designed to advance characters to 3rd level. The house has been burned to the ground many times, only to rise from the ashes time and again—by its own will or that of Strahd. Locals give the building a wide berth for fear of antagonizing the evil spirits believed to haunt it. The wealthy family that built the house practiced the dark arts. Through seduction and indoctrination, they expanded their cult to include a small yet nefarious circle of friends. The cultists regarded Strahd as a messiah sent to them by the Dark Powers. Drawn to Strahd like moths to a flame, they pledged their devotion to a promise of immortality, but Strahd turned them away, deeming the cult and its leaders unworthy of his attention. The cultists withdrew to Death House in despair. Centuries later, the cultists’ spirits haunt the dungeons under the house. The building is unwilling to let the cult be forgotten.
