Fortress Draconis

Once one of the grandest of human cities, Yslin now has a dark heart known as the Dimandowns. And when Will, an orphaned young thief from the Dim, plots to prove himself to his master by stealing a prize from the exiled Elves who share the fetid slums, his theft of the strange artifacts snares him in a web of prophecy. It also brings him together with Kedyn’s Crow, a shadowy human warrior, and Resolute, a Vorquelf determined to redeem his long-lost island home. To them, Will could be the fulfillment of a long-held dream and the last chance the world has to save itself from Chytrine, the northern tyrant who would be empress of the world.
Yet even as Will is tested, a new generation takes up arms where their predecessors failed. Alexia, princess of a dead nation, leads an army to oppose Chytrine. And the sorcerers of Vilwan have fashioned their own hero, Kerrigan Reese, bestowing upon him powers and abilities no human has held for centuries.
Together these heroes travel to the mysterious Fortress Dracconis to stop Chytrine from stealing more fragments of the DragonCrown – a powerful artifact that, once in her control, will guarantee her dominion forever.
