The Hidden City has been exposed, and Devourer is assembling an army from the four corners of the empire to march upon and destroy it. He has with him monsters that he has drawn to their world from across the Polyverse—Golems, Archanoptera, Noon Wraiths. According to the prophecy, the victor of the coming battle will have three armies under their command. Devourer has his, and now Jaden is given the task of assembling that of the rebellion. To do so, he must find and bring back the Elven army, which disappeared from their world thousands of years ago. But doing so risks creating a magical imbalance in the Polyverse that will destroy everything. To succeed, he must destroy the excess of magic in the world, prepare the Hidden City’s defense, and lead the Elves back to their world. But with Devourer already on their doorstep, he will have to bend time to do so. The final battle looms, and any mistakes by Jaden will mean defeat for a thousand years—or the victory of freedom and the return of magic to the world.
