Xandria or Sandria is the region that lies at the eastern end of the Afrocan continent where Ys V: Kefin, The Lost City of Sand takes place. It is said that the ancient kingdom of Kefin once stood and prospered with its mystical alchemy but only the desert remains in the area where the kingdom once stood.
Xandria is located at the boundary between the Afrocan continent and the Eresia continent. Currently, it is suffering from drought, desertification, and appearances of monsters. As a result, the merchant Dorman hires Adol to search for Kefin's alchemy in hopes that the power of Kefin's alchemy can be used to prevent further desertification of Xandria.
