Poor miner Aiden enters Starfall Academy with his only friend Ash—a broken-winged baby dragon. Noble Lucius bullies them, but Aiden discovers silver nails sealed inside Ash, tied to his mother Elena's 18-year-old injustice. He uncovers the Voss family's illegal dragon experiments. Bound by symbiosis, they expose the schemes, abolish forced contracts, and free all enslaved dragons.
