The Avatar: the days without light

there is a legend, greater and older then that of the Avatar. no one even knows if it is true or not. The Legend of the yin and the yang. it is said that at the start of the world, before bending, there where two boys, one named yin lee, and the other yang fon. these two children where the best of friends, although they disagreed on some things. yin was a nice child, sweet and kind. Yang was a ruffian who got into a lot of trouble. one day yang pulled a prank on yin, and it resulted in the death of both boys. a spirit creature came to them, he was known as the creator, and he decided that he wanted to allow the humans the ability to control elements, in secret it was because the more control over the elements they had, the closer they where to the spirit realm, and the stronger the creator could become. but he needed anchors, to keep the spirit realm close to the real world so he used the boys. they where brought back to life and given unique abilities. yin could bend light, while yang could bend darkness. with the anchors in place the spirit world was now free to send chi between the humans and themselves, thus granting mankind the ability to bend the natural element of the spirit they where most in tune with, whether it be fire, water, earth or air. and when the creator had gained enough power from the other elemental spirits he turned himself into a man, and became the first Avatar, to be reborn again every time he died. but this is not a story of the Avatar, this is about yin and yang. after a few years, yin and yang became angered at eachother, yin had said that all elements where equal, while yang stated that Fire was greater. there was a huge battle between light and dark, and for those years the ability to bend was almost lost to the world, if not for the Avatar stepping in. he ended their lives, and returned them to the spirit world, with the Avatar as a bridge there was no need for anchors but yang has tried many times to get back into the world, or to prove to yin that he was right, he was the one who incited the firebenders to start a war with the other nations. now we are in the age after kora, and with the many benders who where turned into non benders the spirit world needs anchors again, so yin and yang have been reincarnated. yang as a fire lords son, and yin as the son of an earthbender. yin most find a way to stop yang before he starts another war with the fire nation.

Along with these, he has almost mastered the use of Blue fire, (a fire that is far more concentrated than yellow and orange, and far more powerful). He is only a few years older than Yang Fon, but acts as his superior.

(good, but yin and yangs reincarnations wouldn't be named yin and yang.)

(so he is actually friends with Lozon?)

(yes, only lozon can speak to yang because their spirits are one, like how the avatar is reincarnated to someone completely different evbery time, but they can still spea with eachother.)
