This is the first time I have heard mention with the sky and red Kachina being a purifier, it reminded me of what I read in an article during a red sky event back during the time I believe around 1000 or the year 1100, where everyone got sick from it, many were dying, they did say it was from the red sky and something fell. I thinking maybe these stories came from those times and it was maybe all over the world because bad things happened in the Americas also around this time. I never clicked with this and the other could be linked to the same thing. I know they were sick and dying and their king died and no one cared because they were all sick and others dying. This is also the years' people or whoever did it, gave people last names everywhere in the known world at this time. No one kept their tribe name, occupation yes, or something to do with something about each person. If you raised pigs your last name may have pigpen for a name, or the meaning of it.

It was a strange thing about this and the naming thing happening about this time. Even in the Bible Jesus was called the son of a carpenter. Others had other names, yet the other countries also got names too. So many died may have something to do with it.
