In the quiet hamlet of Streamwatch, childhood games and whispered legends fill long summer evenings—until the day Aileen vanishes. Taken by the shadowy Mehr and carried toward the dark realms of the Deep Below, her fate seems sealed. Refusing to abandon their friend, Gregor and Baldwin set out on a desperate journey to bring her home. Aided by a mysterious soldier named Cunung, what begins as a daring rescue soon reveals a world far older and more dangerous than they ever imagined—one where forgotten wars, ancient songs, and long-hidden powers are beginning to stir once more.
