Far below skyland where the gods lived there was a vast ocean with no humans just fish and creatures that live deep within it.
There was a man and his wife that lived in skyland. His wife was pregnant and then started having strange cravings for delicacies.
The great tree in the middle of skyland is sacred and no one was ever meant to touch it but his wife wanted some of its bark to eat but he simply could not bring himself to do it.
A hole broke in skylands floor when the man attempted to gather the roots and he wouldn't do it himself but his wife came to get them and he then pushed her through the hole.
when her husband pushed her through the hole the birds hovering below skyland did everything they could to break her fall so she is not killed when she hits the ocean below.
The birds managed to break her fall and then a turtle came to her and offered for her to live on its back and the birds brought materials to build a small hut and to make a mound for the roots of the great tree to grow. As time went on the great tree grew and the beginning of a new world began.
