The Rastavan Ruins (ラスタバン遺跡 Rasutaban Iseki?) ​are ancient ruins where dragons reside. It was famous for having a ferocious dragon in the past, but it had not been confirmed to exist for over 100 years until the events of "Luna Nova and the White Dragon" occurred.


The Rastavan Ruins are ruins located on the outskirts of Arcturus Forest. Fafnir is currently the only known inhabitant, placing there its investment center as well as its security system. The ruins are a circle of crumbling stone boards, with a large underground space accessed from various tunnels around as well as the main entrance.
