Avatar: The Lightning Legacy

I do not own any of the L.O.A characters. In this story Zuko finds out that he can control the weather as well as fire, and he does not understand, since he is a firebender. So he goes to research and finds out that there is a legend about a group of Benders known as stormbenders, benders who could control the weather. He thinks its possible he is a stormbender, and goes to find out the truth. Meanwhile in the storm plains, Rai must take the test of lightning calling, a test to determine whether or not you are a stormbender. They meet and decide not to tell anyone else about the encounter. Meanwhile, they keep in touch. But can such a big secret be kept for so long?
