In the shocking aftermath of the battle in Solara, the heirs arrive at the chilling conclusion that killing the gods will be trickier than they thought. Not only will the gods' bodies need to be destroyed but also their fulcrums, the sources of their divine power. The heirs must return to their respective worlds to find each fulcrum and confront their ancestral deities. But the paths they take are dire, and will require calling upon the unknown-and unstable-depths of their power.

Meanwhile, Orsus, the long dead fifth god, seeks to return to full strength, though their motives and methods remain suspect. Only one thing is for certain: their journeys all lead to the Meridian Forge, the cradle of creation. There, the heirs will determine the fate of every realm as they face their strongest demons yet.
