The land of Ascarlia, a fabled realm of bloodied steel and epic sagas, has been ruled by the Sister Queens for centuries. No one has dared question their rule. Until now. Whispers speak of longships of mysterious tattooed warriors, sailing under the banners of a murderous cult of oath-breakers long thought extinct. A tide of black steel that threatens to vanquish all in its path. Thera of the Blackspear, favored servant of the Sister Queens, is ordered to uncover the truth. As Thera sails north, her reviled brother, Felnir, sets out on his own adventure.

Lukan Gardova is a cardsharp, academy dropout, and—thanks to a duel that ended badly—the disgraced heir to an ancient noble house. His days consist of cheap wine, rigged card games, and wondering how he might win back the life he threw away. When Lukan discovers that his estranged father has been murdered in strange circumstances, he finds fresh purpose. Deprived of his chance to make amends for his mistakes, he vows to unravel the mystery behind his father's death. His search for answers leads him to Saphrona, fabled city of merchant princes, where anything can be bought if one has the coin.

Athera is besieged by the Mistwraith, which blights the land and dims the mysteries guarded by the last fugitives of the old bloodlines. But from a prophecy springs hope: the gifts of two brothers – one dark, one fair, raised on opposite sides of a relentless war – when paired may challenge the Mistwraith’s invasion, though at brutal cost.

It has been twenty-seven long years since the last sunrise. For nearly three decades, vampires have waged war against humanity; building their eternal empire even as they tear down our own. Now, only a few tiny sparks of light endure in a sea of darkness.

It has been 20 years since the end of the war. The dictatorial Augurs, once thought of almost as gods, were overthrown and wiped out during the conflict, their much-feared powers mysteriously failing them. Those who had ruled under them, men and women with a lesser ability known as the Gift, avoided the Augurs' fate only by submitting themselves to the rebellion's Four Tenets.
