Short Summary: Xavier, Prince of the dying planet Philos, discovers its dark secret: the royal family sacrifices people (including his loved ones) to sustain the planet. He rebels, abandons the throne, and spends centuries searching for a way to save both Philos and a mysterious girl tied to its survival. Despite their bond, he leaves her behind to alter history—only to return when she becomes Queen, fulfilling a prophecy he secretly rewrote to protect her.
