Lunaria is a court mage of the kingdom of Sagittaries, dispatched with her comrades to investigate a set of ancient ruins. What seemed like a straightforward assignment falls apart almost immediately. The ruins are infested with monsters, and a mysterious figure appears and strips Lunaria and her allies of their mana — the source that powers all of their magic. She is told the mana will not return on its own. There is, however, a possibility: the ancient jewels of the five Great Mages may be able to restore what was taken. As one of the only court mages still able to use any magic at all, Lunaria sets out alone to find them. The road ahead is treacherous. Lunaria is not your ordinary mage.
