Azula came out of the beach house and finds Aang sitting close to the beach. She looks up in the sky and finds auroras in the night sky. Various spirits dance in the sky. Azula sets next to Aang who just notices her out of bed.
Aang: “Azula! Good to see you up.”
Azula: “You’re the one put those panda lilies into my room, didn’t you?”
Aang: “(face briefly turns red) Too much?”
They sat in silence as they watched spirits dance in the sky as a result of the two northern and southern spirit portals opened plus a new one that opened after the destruction of Banyon grove tree and the tree of time.
Aang: “How are you feeling with everything happening?”
Azula: “You mean how am I taking in the revelation that my father is actually a demon, old as time itself, who used my great-grandfather to wage a century long war based on a lie, a lie I dedicated my life into perusing? Very well!”
Aang nods sympathetically.
Azula: “How did he even do all this?”
Aang: “Every solstice, the moment where line between the physical realm and spirit realm is blurred. Vaatu would use the threads of fate inside the tree and was able to control Sozin’s fate. Next, he sought out your grandmother who spent her life studying the spirits and learning their ways. He manipulated her into believing he was going to win no matter what, so she helped him escape. She astral projects into the tree, Vaatu fuses with her, they go back to her body but Vaatu’s dark power vastly depleted but constructed a human host for Vaatu to inhabit. Ilah died of child-birth and the newborn empty vessel was named Ozai.”
Azula: “What does that make me? Half-dark spirit? It would explain why I was so hateful and…not all there in the head.”
Aang: “No, I don’t think so. Vaatu was reduced to the level of a human soul and needs harmonic convergence for his power to return.”
Azula: “So what’s his endgame plan, cause both realms to be lifeless, useless voids?”
Aang: “Yes, but for only 10,000 years. During his time in the tree, he learned he cannot destroy light anymore then I can destroy darkness. One can’t exist without the other. He’ll use that to his advantage. He’s behind it all, Zula, he linked his life and bending at the giant swamp tree, should he die or lose his bending, both trees will explode. The attack at the earth kingdom during Sozin’s comet was a set up! It was bait and I took it! He used my compassion for all life against me and now a dark avatar is about to be born!”
Aang clutched his fists with fury, Azula placed her hand on her shoulder and he was calming down, she empathized with him about what it’s like to be played by Ozaatu.
Aang: “Anyways, after he got all elements, he faced the last lion turtle, they fought and Vaatu actually slayed the lion turtle by using a energybending technique to absorb its soul. He now has the powers and knowledge of a lion turtle. After, Raava dies, the elemental spirits all benders draw power from will die too but he’ll take their powers next. He’ll bend the energy from within himself and inside Raava and make so Vaatu will draw power from light instead of being weakened like before, while Raava will be weakened by her own power as if was darkness.”
Azula: “And so after 10,000 years. This ‘dark avatar’ will be both light and dark avatar?”
Aang: “He says he’ll be the one true avatar and will create his own avatar cycle after his physical body finally dies. An avatar spirit of balance itself.”
Azula: “Gotta say, It’s a rather creative plan that seems almost agreeable. No wonder he got many people to join the red lotus and follow him, despite the fact they are all about to die.”
Aang: “What I can’t agree with is killing all life in existence for 10,000 years, even if it is to restore balance. There must be a way to end the raava and vaatu conflict for good without sacrificing human lives.”
Azula: “You got any ideas right now?”
Azula: “Well, I’ve seen you pull off victory from the jaws of defeat.”
