I'd considered the Chinese five phases, but wasn't sure if there would be interest. The Wikipedia (http://en.wikipedia.org/wiki/Wu_Xing) has a very basic outline of what it has been applied to in the past.<br/><br/>Interestingly, the five phases are associated with a great number of things outlined in an awesome chart about 1/3 to 1/2 down the page, including five heavenly creatures: the Azure Dragon 青龍, Vermilion Bird 朱雀, Yellow Dragon 黃龍, Qilin ("Unicorn") 麒麟, White Tiger 白虎, Black Tortoise 玄武. That would really be interesting; I've studied a bit of the constellation and mythos about the Five Phases, and a couple of popular anime/manga have included them extensively in the story to a degree.<br/><br/>Pretty fascinating, something I'd love to study more. I'd also vote for the Norse mythology, but I want to see what's more popular. ^__^
