QUICK, WHILE IT'S STILL THERE!
So, what caused me to react like this...
EDIT: Well, it was the opening to The Legend of Korra, but one of the creators of the show has asked that it not be reposted, and since they've given us so much wonderful, it's only fair that I take it off here!
Okay, the tag gave it away. BUT STILL! SO EXCITED! :D By the way, the graphic novel that bridges the gap between the end of the series and the beginning of the new one comes out at the end of January!!!!
