From publisher blurb:
In the hours and days following the Darkfall, countless settlements across the face of Aden were lost, scourged of all life by the hideous nocturnals. Ten years later, those that remain are veritable fortresses, defended every day by the hardy men and women who take up every weapon imaginable to defend their homes. One such village is Syldan, near the Burning Coast of Aramyst, where the survivors are threatened by a horrifyingly familiar danger from before the Darkfall claimed Aden.
