Designed for 11th-level characters! A deadly, new curse known as the Carrion Call spreads rapidly through the Meraz Desert, driving its victims mad with hunger and a burning desire to flee into the sands. To find the source of this affliction, the heroes must challenge gnoll tribes, fiends, and the walking dead to discover the secret of a long-forgotten evil ― the daemon lord known as The Vulture King. Once worshiped as a god, this vile creature threatens to spread his feast of dust to new lands unless someone can find the keys to stopping his unholy resurrection.
