For centuries, the kingdom of Aenor had been plagued with brutal raids from the dark elves. But only once was a prisoner ever taken—his name was Asten.

As the lone witness to his best friend's abduction, a gifted young hunter by the name of Erluc takes it upon himself to rescue him. Racing to save his friend, he stumbles upon a fragment of the prophecy that had cemented his destiny a thousand years before his birth, realizing that the world he lives in faces grave danger and that without Asten, he has no hope of standing against it. With newfound allies by his side, Erluc pledges his life in order to prevent the Mortal Realms from tearing themselves apart, facing down the deadly servants of a dark god. And as new terrors arise, Erluc begins to understand the true meaning of his promise, the price of keeping it, and the consequences if he fails to honor it.
