Avatar: The Last Airbender will soon be ending its successful three-season run. Spoilers mention that in July 2008, the critically-acclaimed animated series will telecast its finalé. Sources also say that instead of the usual 20-episode-per-season run, Book 3 will have 21 episodes including the last chapter. Well, it won't be until two months but it's certainly worth the wait. Meanwhile, episode 15 of the Book of Fire will soon be uploaded to The Avatar Temple. That is also something worth waiting for.
