I am not sure the origin of all these warriors of the rainbow tales but here is a sampling of some writings that I have found. The next three paragraphs have no known source of where they came from.
There will come a day when people of all races, colors, and creeds will put aside their differences. They will come together in love, joining hands in unification, to heal the Earth and all Her children. They will move over the Earth like a great Whirling Rainbow, bringing peace, understanding and healing everywhere they go. Many creatures thought to be extinct or mythical will resurface at this time; the great trees that perished will return almost overnight. All living things will flourish, drawing sustenance from the breast of our Mother, the Earth.
The great spiritual Teachers who walked the Earth and taught the basics of the truths of the Whirling Rainbow Prophecy will return and walk amongst us once more, sharing their power and understanding with all. We will learn how to see and hear in a sacred manner. Men and women will be equals in the way Creator intended them to be; all children will be safe anywhere they want to go. Elders will be respected and valued for their contributions to life. Their wisdom will be sought out. The whole Human race will be called The People and there will be no more war, sickness or hunger forever.
In the time of the Seventh Fire, a New People would emerge. They would retrace their steps to find the wisdom that was left by the side of the trail long ago. Their steps would take them to the elders, who they would ask to guide them on their journey. If the New People remain strong in their quest, the sacred drum will again sound its voice. There will be an awakening of the people, and the sacred fire will again be lit. At this time, the light-skinned race will be given a choice between two roads. One road is the road of greed and technology without wisdom or respect for life. This road represents a rush to destruction. The other road is spirituality, a slower path that includes respect for all living things. If we choose the spiritual path, we can light yet another fire, an Eight Fire, and begin an extended period of Peace and healthy growth.
This next section came out of Rainbow Anthology 1991 Page 32 on a page associated with the 1975 Arkansas Rainbow Gathering.
The Rainbow Tribe is all peoples of the world, all brothers and sisters of the Great Universal Family. It is a tribe not of blood but of the spirit. There is no need to join this tribe, for all are born into it, as all are children of the One Father and the One Mother. But many of the children do not yet know their family, do not yet know it is our Mother the Earth who is sick, that it is we her children who are responsible, that we all need each other, for the issue is now survival, and the task of perserving life on this planet demands nothing less than planetary cooperation.
Within the Rainbow Tribe of All Tribes, therefore, there has been created a society to spread this consciousness, The society of th eWarriors of the Rainbow to exemplify the highest ideals of the min, heart and spirit, to work together and more efficiently bring about a healthy high existence upon this planet as ordained by the Great Creative and Healing Spirit of the Universe.
The Warriors of the Rainbow recognize the true enemies to be Ignorance and Fear, that the only weapons needed to conquer these foes are truth and courage, that in the battle women must take their place as equal warriors beside their brothers, and that the fruits of victory are wisdom and joy. The other names of Joy and Wisdom are Love and Understanding, and these are the two medicines by which the Rainbow Warriors seek to heal the land and her people, and with these medicines men must take their place as equal healers beside their sisters.
The thoughts and deeds of the Rainbow Warriors shall at all times issue from highest feelings of Reverence and Respect. A Warrior must revere and respect the Universal Spirit, the Great Holy Mystery that is in all things and beyond all things.
