The Wasp Empire has commenced its great war against the Lowlands, capturing the cities of Tark and Helleron and defeating the Ant-kinden of Sarn in a pitched field battle. Now General Malkan’s Seventh Army, the Winged Furies, waits for reinforcements before pressing on to Sarn itself. Malkan’s victory over the Sarnesh was accomplished by a new weapon, the snap bow, devised by the former Lowlander Totho, now an apprentice of the Empire’s foremost artificer.

The Wasp Emperor, however, is distracted by the promises of his slave Uctebri, who has pledged him eternal life in return for the blood of the Emperor’s sister, Seda, and possession of the mysterious Shadow Box, a relic containing the power of a twisted ritual that turned the forest Darakyon into its current haunted and lifeless state.

Amongst the imperial agents sent to retrieve the box from Collegium were the Wasp mercenary Gaved and the face-changing Spider spy Scyla, the latter of whom has stolen the box and intends to sell it for her own profit.

Stenwold Maker, meanwhile, faces the task of attempting to unite the squabbling Lowlander cities against the Wasp menace before the imperial armies advance once again. His worries are increased by the loss of his niece, last seen fighting alongside the Sarnesh. Unbeknownst to him she has escaped her imperial captors, released by her former friend Totho, and carries with her the precious blueprints of the new snapbow.
