Iopos: Lair of Deceit is a 256-page sourcebook that lays bare the intricacies of Barsaive’s most secretive city and family. It presents the surviving history of Iopos, secrets of the Holders of Trust—the Copper, Silver, Gold, Orichalcum, and newly revealed Malachite Branches—and the current state of Jerris, their most recent acquisition. Even some of the darkest places in Iopos, such as the Thricewoven Flesh Forges and the abominations crafted within.
Players will find invaluable information for infiltrating this city as agents of external powers, and descriptions of daily life for Iopan characters. Gamemasters will uncover the layers of deception in a city that is always watching, plot hooks to bring characters to the lair of the Denairastas, and ideas for groups who join the Holders of Trust and execute their masters’ plan to conquer Barsaive. All of this plus new creatures, Horror constructs, opponents, masks, thread items, and revelations about the Oath of Affirmation.
