Now Devourer has destroyed the ancient city of Marleborn, a center of resistance to the Empire, by spreading the plague of Noon Wraiths. Headmaster has also gone missing while on his own mission to destroy another of Devourer’s machines. If he has been captured or killed, it could lead to the Hidden City’s location being revealed to Devourer, putting the rebellion in danger. The rebel council wants Jaden and the Free Seekers to search for Headmaster in the Imperial Reliquary, based in the ruins of an ancient Elven City. Jaden insists that they must first rescue the refugees from Marleborn. Thousands have fled into the wilderness, and winter is coming. Many won’t survive without help. The outcome of whatever decision they make will determine whether the rebellion succeeds...or Devourer triumphs.
