The Hunger from Below

From publisher blurb: The Freedom Games summons competitors from throughout the civilized world, but the events are doomed. Agents of evil have a vile plan for the unwary citizens of Omnilibertas, and heroes must rise to face terrifying foes, or the free city could fall forever to an ancient horror. Can these raiders be stopped? Who sent them? What do they want? The Hunger from Below is the first installment of The Ravenous Ruin, a six-part quest taking players from 7th level through 12th level. Within are 26 pages of thrilling adventure, new monsters, magical items, plus a primer on the city of Omnilibertas, its eccentric freedom-minded citizens, and an overview of Hastroi, God of Valor.
