The Story starts immediately after Aang and Katara kiss, I don't own avatar ok and this is my first avatar fan fiction
"Aang I'm sorry about what happened at ember island I was confused and" Aang put his finger on her lips
"It's ok because everything is fine now there is no more war and we can relax" Aang said with a smile on his face right before they kiss but then Aang throws her out of the away and shoots Air at a ball of arrow coming directly at him and blocks the arrow shot from a Masked Man
"Katara you go inside I will take care of this" Aang said then Katara ran inside but the second she did the masked man ran away then Aang soon followed
"Avatar you will never catch me" As he ran away but the next thing he knows is that Aang is in front of him and the masked man is knocked down Aang earth benders so he can't get away
"Who are you and what do you want" Aang said pointing his staff in the masked man face
"I am just a messenger from a greater power you better watch out because this greater power is coming to get you and take over the world" The masked man said then in a fire came down Aang jumped away and the masked man was gone then Aang hurried back to the Tea Shop
Just as Aang gets there Katara is telling everyone what she just saw with out telling them about kissing Aang
Aang arrives in the shop "I think we aren't done yet" Aang said then he told everyone what happened then he when he was done a note was lying at the door "What is this" Aang said then he read it out loud
"Avatar if you want to find out who is the greater power you most gather items from across the world you will find out these items later in a message"
"Is that all its says" Sokka said
"Yeah" Aang said looking at everyone, Then Zuko goes and looks at it
"This so weird" Zuko said then hands the letter to Iroh
"There is only one greater and that is when I went to go see the sun warriors, when I met the Dragons I heard them saying" Iroh Said "A third Dragon" the 2 dragons said "I knew if I told any else they might try and destroy it to so I told no one
"You Mean there is another dragon" Toph said amazed
"Yes and this dragon I think is the strongest of them" Iroh said looking a little worried
"And he wants me" Aang said looking down on the floor "I need to think about some stuff I will be outside ok" Aang said confused and angry as he left but then Iroh followed
"Aang you need to know fighting a dragon will be much harder then fighting my brother" Iroh said
"I know that is the hard part how will I be able to fight him" Aang said confused
"I can teach you more fire bending and we you can master all four elements" Iroh said "But that is for tomorrow but until then I'm going inside to drink some more tea you should come in" Iroh said
"No thanks" Aang said still thinking about the new challenges head then Katara and puts her arm around him "We'll never get some time alone" Aang said looking sad
"That might be true but I'm going to have to learn if I'm going to be the Avatar girlfriend" Katara said then Aang got a small smile on his
"Thanks Katara" Aang said then hugged her
