Soratami
From MTG Salvation Wiki
Soratami or moonfolk are an enigmatic race of humanoid beings who dwell in Kamigawa's clouds. Physically, they are slim, posses blue-gray skin, and have long ears which they wrap over their heads (a reference to the Japanese folk relationship of rabbits and the moon).
They watch over the world below, mostly indifferent to the concerns of the surface folk. They have a high emphasis on the study of magic and have some of the most learned mages on the plane.
They live within floating palaces, of which their greatest structure on the clouds is a palace named Oboro (or Otawara).
