How did the warriors get their name?

Answer 1

In modern times, it originates from the ship "sv Rainbow Warrior" used by Greenpeace to campaign worldwide about environmental issues. However, the ship's name itself was inspired by North American Indian prophecy which foretells of a time when human greed will make the Earth sick, and there will be a mythical band of warriors who will descend from a rainbow to save it.
