Avatar Korra steered the boat out of the Republic City bay. After she had set the clear path, she went downstairs and went to sleep.

Avatar Korra looked around she was no longer in the boat she was in the Fire Nation. The sky was red. She then saw a blast of lightning flying into the sky over the horizon. She ran up to the top of the hill. She looked into the mountain. There Korra saw master Katara dueling a Firebender. Zuko was on the floor injured. A blue flame emerged from the firebender when Katara tried to heal Zuko. It blew up in her face. The girl Firebender blasted Lightning at her. She kept spamming Katara with blue fire. When she chased after Katara she ran and found a chain. She grabbed it and then brought water down around her and the FireBender and froze it. Katara thawed herself and tied the chain around the Firebender. Then, Katara ran and healed Zuko. Then Aang and Roku appeared. They spoke.
"Azul, Great Grandaught of me",said Roku.
"Azul Zuk, sis",said Aang,"Azul buildin' last stand against rep, bin lockd up for whole life-." He cut off. They both fazed out. Kyoshi and Kuruk appeared behind them but before either of them could say something, they faded. Korra then woke up.

"So you're saying you've had another one of these dreams",said Mako.
"Yes",said Korra,"Whoever 'Azul' is, we know she is a Firebender and can bend blue Fire and lightning."
"I don't know any blue Firebender, I didn't even know that was a thing",said Mako,"All though I wish I was a blue Firebender."
"Apparently she is building a last stand against whatever 'rep' is",said Korra.
"Well look on the bright side",said Bo Lin, cheerily,"You might actually be reconnecting with your past lives."
"Ya, I also saw the three avatars before Aang",said Korra,"Roku said 'Azul great grandaught of me', which I assume means she is the great granddaughter of Roku."
"What did the other two Avatars say",questioned Asami.
"Kuruk and Kyoshi",said Korra,"They said nothing, they fazed out."
"That's odd",said Mako. They walked up to the top of the ship. They saw the vast ocean ahead of them.

"Ok right now we are on a direct path to the Fire Nation",said Mako,"We should be there by noon tomorrow, but we should all get some sleep now." They all went downstairs.
"I think I will have another one of these dreams tonight",said Korra,"I'm kind of... hoping, I want to reconnect and learn more about Azul."
"I don't think Azul is the actual name",said Mako. They went to sleep.

Standing in front of Korra was Avatar Aang, Roku, Kyoshi, Kuruk, Yangchen, Tzeno, Uru, Imiq, Jamphel and Lua.
"We're starting to reconnect Korra",said Aang in an almost clear voice,"There a few more things we need to do before we can fully reconnect but that is beside the point."
"I want to know who Azul is",said Korra.
"Ah yes, Azul is what you've been hearing, her real name is Azula",said Aang,"and she is Zuko's psychopathic Sister."
"So does that mean that Zuko is Roku's-",said Korra.
"Yes, he is my great grandson",said Roku.
"After Sozin's comet Azula went insane",said Aang,"Zuko locked her up in an institution, she was let out to help him find their mother, Ursa, Azula then came back and she was Locked up in the institution again—." He started blinking.
"I've t-told you all you need to know about Azula's past, she is now an old woman, she is still insane in the head, but she is gathering support, she wants to make one last attack in her life, she wants to attack the Republic, and kill Zuko."
"Who are her followers",questioned Korra.
"When she attacked Ba Sing Se, her followers were the Dai Lee, I assume she will go for them since Wu got them out of Ba Sing Se, and probably some people who thought that Ozai was a good FireLord",said Aang. He faded out. They all did. Korra woke up back into reality.

"Azula is Zuko's psychopathic Sister",said Korra,"She's gaining power again, she must've escaped the institution, she has some followers."
"So that's why he told you to get Zuko",said Mako,"To take down Azula."
"I don't know why we need Zuko",said Korra,"Maybe to face Azula and we can take on her followers."
"But What is rep",said Mako?
"We'll Rep could mean multiple things, but the thing that makes most sense is Republic",commented Asami.
"But... if she's attacking the city",said Korra.
"The City could have more damage inflicted",finished Mako.
"Then the repair efforts would be problematic",said Korra,"We can't let the city be damaged any more."
"Land Ho",exclaimed Bo Lin and he dragged Mako to the edge of the boat,"Look Mako, where mom grew up."
