In the broken borderlands of Ardentia, Lyra Solenne-last heir of a fallen noble house-discovers a blood‑crimson locket that binds her fate to an ancient prophecy and awakens a power she cannot control. Haunted by visions of a blood‑red moon and guided by mysterious letters from the Wanderer (Yashu in shadow), she must navigate treacherous courts, secret societies, and shadowed battlefields. As war looms between empires and the locket's curse demands a heartbreaking sacrifice, Lyra learns her greatest enemy may lie within.
