Citizens of the free city of Zobeck are going missing! Catacombs beneath the streets may provide answers, but what lurks in them may not enjoy company…

Who will uncover and stop the foul and ghoulish workings? Will your adventurers have the fortitude and ambition—or the greed and cunning—it takes to put a stop to them?
