Desert Oasis is a desert in Southeastern Ylisse. It is rumored that it is home to a hidden mirage village. If Miriel or Chrom visits a specific village here, Laurent will join the army. After visiting 4 mirage villages, upon standing on a specific tile on the map, the army will receive a Goddess Staff.
- The mirage village hidden in the desert may be a reference to Arcadia in Elibe.
