The Araba (Japanese: 荒場; literally: "Wasteland") was a region within the Towabara Plains, on which Eiganjo Castle stood. It was devastated in the Kami War, and this devastation is reflected in the meaning of its' name.
Reito was a decimated, abandoned human city on the Araba where the kami first attacked the people of the material world. Its name reflected this, meaning “ghost city” or “city of spirits.”
More than 1200 years later, the Araba was replaced by the city of Towashi.
