In the shadow-haunted city of Vaeloria, where stars have been silenced by the tyrannical Silent Council, Lira, a young Singer, discovers her mother Avara's pendant and journal, awakening a forbidden melody tied to the mystical Starheart—a crystal orb that holds Vaeloria's lost light. As Lira's song stirs the city's forgotten magic, she becomes a target for the Council's enforcers and Veyra, a fallen Singer whose corrupted pendant binds her to the High Warden's will. Joined by a band of rebels—scarred warrior Kael, fierce Sana, guilt-ridden Ysme, young Jiro, mapmaker Toren, and elder Mira—Lira embarks on a perilous quest to reclaim the Starheart from the Council's tower, pursued through sewers, storms, and skyship assaults.
