DUNGEON CRAWL CLASSICS: CITADEL OF THE DEMON PRINCE

An apocalyptic cult of demon worshipers has been kidnapping farmers from the local hamlets and offering them up as sacrifices to their blasphemous idols. The heroes are called in for what appears to be a simple mission: hunt down the demon worshipers, beard them in their lair, and demolish their dark abbey, down to the last stone. But this cult is under the direct control of a demon prince with much larger ambitions. The heroes' exploration of the dark abbey soon leads them into a portal to another plane, where they discover the demon prince's hellish scheme -- and learn they have only hours to save their world from being destroyed! Can they defeat the demon prince in his own evil citadel?
