Long ago, the four nations lived together in harmony. Then, everything changed when the fire nation attcked. Only the Avatar, master of all four elements could stop him, but when the world needed him most, he vanished. 100 years passed and my brother and I discovered the new Avatar, and airbender named Aang. And although his airbending skills are great, he still has a lot to learn before he's ready to save anyone. But I believe Aang can save the world.
This is one hardcore Kataang and Makorra blog, but even so, the occasional Borra or even Zutara quote may just pop up.
