The NS were decimated at the Battle of Rendezvous Point deep in the Everglades. If they weren't killed they disappeared into the swamp, never to be seen by me or Nokosee again.
Plus, from what I can gather, that "Old Native American Prophecy" shown above could be nothing more than "fakelore," the product of a creative reimagining between authors William Willoya and Vinson Brown in their book Warriors of the Rainbow published in 1962. According to the Wikipedia article, Bob Hunter, co-founder of Greenpeace, was inspired by it, later christening three Greenpeace ships Rainbow Warrior.
But, I can see how it could easily be mistaken for the real thing, ie, a Native American prophecy.
I can also see how Brown, a white evangelical Christian who is also the publisher-- would use the "prophesying" material gathered from many tribes by Willoya (an "Alaskan Indian") to evangelize the tribes. In the book, the "prophecies" are used to bolster the New Testament prophecies of the Second Coming of Christ. Critics have described it as pushing a "covert anti-Semitism throughout, while evangelizing against traditional Native American spirituality."
So in that case, the NS definitely aren't those Warriors of the Rainbow.
But we are (or were) a mixture of races and faiths as the picture from my wedding day shows as some of us gathered together beneath our own reimagination of the American Indian Movement flag against a backdrop of the ever-burning Everglades.
