Reah is a mysterious blue-haired poet in Minea who asks Adol to find her lost harmonica.

Just like Feena, she later reveals herself to be one of the twin goddesses who governed over the mythic kingdom of Ys.

After the fall of the Eldeen civilization, she and her twin sister Feena came to Esteria with the black pearl. With the help of the six families who were well-versed in magic, they built the kingdom of Ys. The kingdom prospered under their guidance until the series of disasters befell Ys, causing the portion of the kingdom to float. In order to put an end to the disaster, the twin goddesses sealed the black pearl with their wings and fell into a seemingly-eternal sleep until the seal gets broken 700 years later.
