PLOT information (READ THIS DANGIT!!!)

Ok. the plot got really messed up before, so now I'm just going to specify. What we need to pretty much happen is get an avatar (Airbender please!) and have maybe four or five people to find/accompany them. we're starting in the northern water tribe because that is the easiest. I'll update important plot pieces as we move along below, so check back often.
Also guys remember, you don't have to be attention hogs with your characters. Of course they can have backgrounds and everything, but don't be all like "Bob is the only one of his kind in the world, and the future of humanity depends on him because he's crazy awesome."
unless of course you're the avatar, who NO ONE IS YET!
