Guess there aren't enough Avatar/LOK fans here for a topic huh? Well, here's one now.
http://avatar.wikia.com/wiki/The_Legend_of_KorraAs stated, this is a sequel series to "Avatar: The Last Airbender", where the avatar in the next cycle is Korra, a headstrong 17 year old girl from the Southern Water Tribe, one of the nations in the world of Avatar. Like Aang, she has the ability to bend all four spiritual elements, water, earth, fire, and air, and is a bridge between the Spirit World and Physical World. There have been two seasons so far, Air and Spirits, with the next season, Change that is supposed to come out soon.
