A deadly curse known as the Feast of Dust 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 strange affliction, the heroes must investigate the plagued city of Dimayen, challenging fearsome gnoll tribes, nihilistic daemons, and the walking dead to discover the secret of a long-forgotten evil—a powerful daemon harbinger called the Jackal Prince of Famine. Despite the efforts of an ancient secret society, this twisted, unholy monstrosity walks the world again, threatening to spread his apocalyptic curse across all of Golarion! To stop the demigod's return, the heroes must uncover his three vile siblings, now bound within malevolent artifacts, and use their combined powers to stop the Jackal Prince before the entire world feels his corrupting touch.
