Sora No Kuni (空の国) is a mountainous land with many high top forests and floating islands. The land was created from the blood of The Crane God, Tanchosuru Kami. He was rumored to purposely stab himself in the intention of making a land. He then raised the land in search of rubies, making the islands that float today. Once he found the rubies, he plucked a feather from his crown and made a son from the soul of the ruby and the feather. Once he made the child, he decided to slumber in the highest island, high up in the clouds.
Nobody knows who this child is, but they could probably this land...
