The Well of Echoes

Two hundred years after the Forbidding was broken, Santhenar is locked in war with the lyrinx - intelligent, winged predators who will do anything to gain their own world. Despite the development of battle clankers and mastery of the crystals that power them, humanity is losing. Tiaan, a lonely crystal worker in a clanker manufactory, is experimenting with an entirely new kind of crystal when she begins to have extraordinary visions.

Santhenar is on its knees. The war with the alien lyrinx drags on, and humanity is losing it, but there is worse to come. The Aachim have invaded with an irresistible force - a fleet of battle constructs. Cursing humanity for the loss of Aachan and his own clan, the embittered Aachim leader, Vithis, demands half the world in reparation. The council is in no position to resist. But even if they agree to his demands, can anything satisfy his thirst for vengeance?

The node has failed, rendering humanity's battle clankers and the Aachim's constructs useless. The battle has been lost. Now hordes of alien lyrinx are swarming out of the tar pits of Snizort, intending to fall upon the survivors and destroy them to the last man. Tiaan is held prisoner by a vengeful Vithis, who is determined to extract her geomantic secrets at any cost. For his failings, Nish has been cast out and branded a traitor while Irisis, accused of high treason, has been forced to flee for her life.

In a few minutes of overwhelming violence the Council's air-dreadnought fleet has destroyed Fiz Gorgo's defences. Xervish Flydd, Irisis and their allies have been condemned to die in a brutal aerial spectacle designed to reinforce Chief Scrutator Ghorr's power and majesty. Nish is their one remaining hope. But Nish is trapped in a burning watchtower, and hunted by both the scrutators and his former lover, Ullii, whose twin brother he accidentally killed.
