People in the beginning lived in the spirit lodge underground, waiting for the earth to be prepared for them to live there. Iktomi, the Spider, and Anog-Ite, the double-face woman. Anog-Ite was once Ite, and Iktomi was once Woscape, until they were tricked by Gnaskinyan and were punished and banished to the surface.
I promise to never do anything to you again.
I'm bored. Torturing you is no fun. I need new people.
Fine. I'll send my wolf to go convince them.
Wow this stuff is so cool! We should go with the wolf to the surface.
When the people got to the surface they realized that the work was hard and by the time winter had come they didn't have enough food for everyone and they starved and froze. They sat down and cried, but the creator heard them and was upset that they didn't listen to him and stay underground. He then punished them turning them into beasts, now called the bison.
The creator then lead the people who had stayed behind and listened to him, to the surface telling them it was reading for them. He then showed them the bison telling them they would learn everything they need from them.
When they left the cave, the creator shrunk the hole so small that nobody would be able to fit through it. And then left it as a reminder so they would always know where they came from.
