2 Avatars?! (Legend of Korra Fanfic)

I'm guessing by the title that you were expecting 2 avatars that bend. Well, you expected wrong! 1 bends, the other well...doesn't! Actually, the second "avatar" doesn't even live in the same dimension! Her name is Ariella, the princess of Eraklyon. Her powers also consist of the 4 elements, but her powers work a bit differently. One night, she is cast to Republic City and has no idea how to go back. She becomes aware of the threat of Amon and his Equalists. She meets Korra, Mako, Bolin, and Asami at a Pro Bending match. She feels a bit out of place in Republic City because she is used to the royal treatment. She has not told anyone in this world of her powers, but they may reveal itself when Republic City is in need of her Winx!
