In the divided realms of humans and long-lived Fae, nineteen-year-old Ronan Koa becomes the first student from the Aru-Vakai, a superhuman warrior clan descended from many ancestral peoples. Their aura once protected their bodies and magnified strength, but after saving a powerful Fae centuries ago, it became a channel for elemental artifacts and spellcraft. At the prestigious Starfall Collegium, Ronan must protect twin noble heirs, one attuned to the highest solar tier and the other to the highest lunar tier, while they learn magic across three dangerous years. A hidden stranger is hunting their rare power, and Ronan’s growing feelings for both sisters threaten to become as dangerous as the secrets buried beneath the Collegium. The series blends academia, romance, dark mysteries, action, mature themes, and quieter moments of fae life.
