This adventure presents a lavish and strange competition of magicians, inventors, and mountebanks vying for a fabulous prize. When the Crystal of Ciz goes missing, the PCs must contend with corrupt merchants and demon-bound witches to reclaim it, relying as often on deduction and investigation as swordplay and spellcraft to solve the crime. Magnificent Machinations at the Great Exposition of Marvels is a softcover adventure for 3rd level characters. Inside it are details about the City of Cuirnif, the Manse Ashtark, and a new spell for your DCC Dying Earth campaign. Although designed for DCC Dying Earth, it can easily be integrated into any DCC RPG setting with minimum changes.
