Hi! This show, by far, is one of my favorite shows! My dad and I would watch it all the time, and we even have the movie! I cried when the series ened, but can't wait to tell my dad about The Legend of Korra!
I may or may not make a story out of this, but here are my characters and their past:
Luna and her sister Oceana were expert Waterbenders. The 14 year-olds care deeply for the Moon and Ocean spirits and visited the Spirit Oasis often. When they were little, there was another Fire Nation attack. They were caught in the burning palace and were breathing in to much smoke. They fainted and when the Fire Nation retreated, they were found by a guard and taken to the Spirit Oasis, just as Yue had. They were dipped in the waters, and Luna's brown hair turned white, while Oceana's turned jet black. One fateful day, the girls were walking over to the pond, only to see and Earthbender fishing in the Oasis. Frantic, they ran to the man and Oceana scolded him while Luna tried rescuing the two koi spirits, Tui the Moon, and La the Ocean. The man walked away, looking embarassed, by not caring to much that he just killed the two most important spirits. They brought balance to the world. The world turn blank and white, and the water level was dropping. Luna put her hands on Tui and she fell, her body disappearing. Tui, now Luna, flopped back into the pond. Oceana hesitated, but then did the same.
{I may or may not turn that into a fan-fic, with a better storyline.}
