korra's the avatar, so you've gotta (dealwithit) wrote in the100,
Ah, sorry! An Avatar was created as the result of a human fusing with the light spirit, which resulted in him being able to control all four elements where normally humans were only permitted to hold the ability to master one. Because of our connection with a spiritual force, the Avatar energy is also reborn after its human host dies, so there's always an Avatar in the world and we're always connected to our past lives, so to speak.
