Then we manifest together as a spirit, while my body sleeps. She's a good spirit, she's the spirit of light, one of the oldest spirits there is. She existed before...well...pretty much anything. And there's a dark spirit, too, and every thousand years or so, they fight for control of the world. So a very long time ago, when humans were new and only spirits could control the elements, a human decided that humans should have that power, too. And he did a lot of things to get it, some of them good and some of them not so good, and he was banished to live with the spirits. He got caught up in the battle between light and dark, and the spirit of light fused with his soul, to be strong enough to beat the dark.

Ever since then, the soul of the Avatar and the spirit of light have been the same thing, reborn every generation to protect the world. I'm the latest one, I was born with Raava as a part of me. That's her name, the spirit of light.


Uh...no, but we have giant robots. Kind of.
