Guided by clues scattered through myth and modern Athens—carvings at the Parthenon, riddles in the Library of Hadrian, and a forgotten mural in Omonia Square—the girls uncover their unique powers. Lila’s art manifests protective auras, Athena’s knowledge activates ancient runes, and Zoe’s voice commands spirits. They train under a disgraced historian, Dr. Elias , who once studied the Eidolon… until he tried to exploit their magic.
