The traitors who brought the powerful sphinx down have fled with plagues and other magical weapons stolen from Skyhold's Vault, intending to use them against the Havath Dominion, no matter the cost to the rest of the Ithonian continent. Havath teeters on the edge of collapse after their failed invasion of Skyhold, and the nations and monsters of Ithos circle like vultures. The Dominion has no interest in going down without a fight, however, and there are few depths they're unwilling to sink to for survival.

Kanderon's surviving allies are working desperately to stop both the traitors and the Dominion, but the situation is worse than they know. The traitors didn't steal plagues at all. They stole the Tongue Eater, a weapon capable of devouring entire languages, and unless they're stopped, it threatens the fate of the entire continent. Hugh Stormward and his friends are the only ones who know the truth, and there's no one they can trust with the knowledge. Even with the fate of the continent on his shoulders, however, Hugh doesn't care about any of that.

He's convinced that Kanderon is still alive, even if no one else believes him, and he's willing to do whatever it takes to help her.
