Winter has enveloped the tribes, leaving the Holy War with a burnt Katakla, betrayed Toriati, and a ruined Nakar state. The Ethan of Nakara flees to Mithrina, where he makes a deal to save his tribe that no priest has ever agreed to before. Alexandra Toriati, whose gift of weaving has become destructive to herself, goes to the core of Gemma in search of an answer to how to take revenge on the tribes. And to top it all off, Tsembenga comes into play, where the death of one of the priestesses upsets the precarious balance of power. With the metal god now conscious, each hero realises that in order to build the future, the mystery of the Machine's past and the Age of Steel must finally be unravelled.
