The Elements: The Legend Begins

~Dedicated to the Creators of the show Avatar: The Last Airbender. Thanks for leaving out the bender if vines and flowers so I could include her in my story.~
Over a thousand years ago, in ancient China, the wall is under attack by the Shadow Lord. Only five teenagers can stop it-- Ash, Kora, Kendragon, Sojourner, and Vivian-- the embodiments of the five elements. Yet, as they run to stop it, the Shadow Lord sends them into eternal life, where whenever they die, they are reborn into the next century, without any memory of the life they had before, so they can't interfere with his plans to destroy ancient China's wall. But as they approach the year 2016, the Shadow Lord's magic seems to be wearing off whenever one if the embodiments go to somewhere where they spent their first lives at. With the help of new friends, they'll be able to train and face the Shadow Lord once again.

But what will happen?

Will Sojourner's lost father be found? Will Kendragon find out how they all got their powers?
Will their pasts all be revealed?

Or will they die trying?
