Be’naj and Saffron return to Zeblon, the city of Saffron’s enslavement, to enlist the aid of the Circle of Twelve. They reveal the existence of a book, the Grimoire Precario, that details the workings and locations of Elisahd’s Touchstones – the sites binding the world to the Planes of the four Elements. Normally in balance, the Touchstones are in danger of being realigned to the Plane of Shadow by the Dread Lich, Hadrian No More. In order to lock the Touchstones first, Be’naj and her companions will first have to infiltrate the Iron Fortress of Hadrian No More and steal the Grimoire Precario out from under him.
