Avatar: Chaos Water

"First of all, why do I have to raise this child? Secondly, why does it have to be me, and thirdly, how did I become enlightened?" Shisui asked somewhat dismayed, he had even activated his ability to observe everything around him. 

There was something very interesting when he saw the auras of all the Avatars, they all had a similar aura but with just enough variation to stand out as unique individuals, but in a way this had an explanation, technically they were the same person but reincarnated for almost 10,000 years. 

"If I may, young man, I believe I can answer your three questions," an old man with gray hair, black armor, and a calm gaze approached Shisui.

Remarkably, all the Avatars seemed to show him a touch of respect, and no wonder, for he was the first Avatar, Wan. With him, this long cycle and the Avatar's long mission to bring balance to this world began. 

"This boy is Aang, an Airbender. I assume you know what that means?" Wan pointed to Aang, who looked a bit shy when he was pointed out to, and when Shisui turned his gaze to him, he frowned at what he noticed.

"He..." Noticing only Aang, Shisui could see a serious problem with the young man's condition. 

Ignoring the fact that he looked much older than his version in the original story, his health was in a terrible state. There was a 'leak' in his aura as if he were a vessel with a small crack in it. 

The water in the jar was slowly leaking out, perhaps without much significance at first, but when the contents diminished to a certain point, it was obvious what would happen to Aang: he would die. 

"As you have noticed, Aang is slowly dying. The Avatar is about to end if he keeps this up," Wan's words seemed to bring coldness to this part of the spirit world, but strangely, Aang didn't seem to show any reluctance to the situation and even laughed. 

"I have no problem with that, though I regret not being able to go to the East and West Air Temples," Aang smiled, though Yangchen slapped him on the back of the head for saying that, making Shisui laugh. 

"So you want me to teach him how to keep his life essence within him and not die?" Shisui pointed out the key point, causing Wan to nod. 

"Yes, we saw what you did there, we never thought that you could do something like that. Although Avatar Kyoshi could teach him the Immortality Technique, it would not solve his fundamental problem, because Aang's problem is not in his physical, but in the spiritual aspect of his being.

Her technique will allow Aang to bring his chi, which is scattered throughout the world, back into himself, allowing him to live out his allotted time without problems, as his life should "flow" properly, repairing the cracks in his being. 

By the way, to gain a few more years, but the most important thing is to prevent his premature death by completely reassembling his vital essence," Wan's words made Shisui sink into his thoughts. 

Help the Avatar live longer? That would change so many things, outright, Korra would not be the Avatar, but in a way, it would allow the next Avatar to better adapt to his role in the future. 

Korra was born in a time of transition and rapid change, with Aang's untimely death and the lack of a foundation of status for Avatars in a time of rapid change causing a lot of problems for the young girl. 

Then again, wasn't Aang supposed to be his "enemy"? At least someone who doesn't know Shisui would think so. To him, the Avatar would not be an enemy, but a potential ally, someone who could do more than just be the guardian of some unruly children on a playground.

Who better to lead humanity to the stars than a fusion reactor with legs? One who could grow up and consult with his past lives to avoid manipulation by vested interests, a being who could properly lead humanity into a prosperous future. 

Many focus only on balance, or rather the status quo. The balance will never be the same in any era, it will never be letting the world fall behind to maintain the status quo, that would not be balanced, that would be backwardness. 

No, for Shisui, the Avatar was the being who should not only serve as a bridge between the earthly and spiritual worlds but should also proactively work for human prosperity.

Tough when needed, fair when needed. So Shisui looked at Aang, who noticed his gaze and raised his hand in a silent salute. 

"Apart from my so-called new technique, I will teach you above all the new common sense of this age. I don't want an Avatar who is blinded by the first nonsense he hears, but an Avatar with a critical mind. 

You can expect absolute fairness from me in this regard, I don't want a naive or pusillanimous guy out in the world ruining everything because it's not the balance I had in mind," Shisui said, making some Avatars nod, though others seemed to be angry with him. 

"You're just a stuck-up brat, who are you to 'educate' the Avatar, just teach him how to survive!" an Avatar in obvious Earth Kingdom clothing stepped forward to speak, but Shisui just shook his shoulders.

"Aren't you the Avatar who wanted everyone to have their 'half pear' or something? Don't give me that nonsense. I just don't want the most powerful being in all of humanity to be ignorant, I don't want to change his ideals, I want him to be able to see the world as it is," Shisui pointed out, ignoring the ugly look the Avatar gave him. 

"On top of all that, give him a good lesson in what balance and equilibrium is. I don't want a megalomaniac Avatar or one with a Saint Mary complex running around thinking what he does is right just because he is the Avatar, I don't want a martyr, I don't want a tyrant" Shisui's words angered some Avatars, those who were recorded as the most innocent and kind-hearted, or in Shisui's words, idiots. 

Even those who were particularly cruel and strict, because many Avatars had a very serious problem within themselves: they thought that what they believed to be balance was the right thing to do.

Not only did they neglect many aspects, such as the problem with Kuruk and Yangchen, but some Avatars even acted contrary to the actions of their previous lives, undoing changes or progress simply because it did not fit their strange sense of balance. 

He wanted Aang to think for himself so that if someone told him that the Fire Nation was evil, he would not just believe it, but go out and find out if it was true. 

When he saw things like guns, he wouldn't just jump to banning them just because they 'took lives', the problem was never the guns, it was always the person using them and the way these objects were handled in everyday life. 

Because a pencil could be as dangerous as a knife, and a rock could be as deadly as a bullet, especially with the influence of Benders in this world. Although absolute justice and absolute balance were impossible, I wanted him to have a broader view, but also to be able to focus on one point.

I didn't want him to be a pacifist, that would be to eliminate the poor boy's identity, no, what I wanted was for him to have more determination, and critical thinking, to be an exemplary Avatar, a true leader to guide the world.

"Calm down, we are not here to argue with the sage. I agree that Aang should learn not only how to save his life, but other things as well. Remember, it's his turn to live, we can't just force our way of thinking on him," Roku said, coming to Shisui's defense as he watched the other Avatars murmur over the boy's words. 

"Thank you, Avatar Roku," Shisui bowed respectfully to the old man, who was technically his 'grandfather', at least in the cultural sense of things. 

"Exactly, I have seen the dangers that recklessness and preconceived ideas can cause, of all people know that, I of all people know that," Wan said, causing the Avatars to calm down and remain silent. 

"Old man, you have to tell me about your life one day," Shisui suddenly said, causing Wan to burst out laughing at his words. 

"One of these days! Now let me answer your other questions. Although you should already have a clear answer to them. It has to be you because you are the one who knows such abilities, we are Avatars and look down on the earthly world from here, but it's not as if we can know or know everything.

We also know your attitude towards teaching, you have no problem with sharing your knowledge with others and it is obvious that you love it. Besides, you owe us a favor. 

The day we all appeared in the spiritual reflection you created, we protected you from the attention of certain annoying and dangerous spirits. Sure, we appeared on our own and it even caused Aang's current situation, but if we hadn't, you would have attracted certain annoying entities to you, although it seems some have been noticing you lately," Wan said, causing Shisui to nod. 

Not only was there the problem that some normal spirits had approached him in the last few years but since Musu had attacked him that day, he had not been attacked again.

That corruption just belonged to a being that he decided not to think too much about, especially in the spiritual world, who knows? Maybe he would be drawn to it, and the spirit world worked in a strange way to keep him out of trouble. 

"I like to teach, and as you already know, I'm more than willing to teach Aang, I could even teach you if you want," Shisui didn't forget to look at a certain annoyed Avatar with a smug smile on his face. 

"Listening to the teachings of a sage is always welcome," Kyoshi said, and the other Avatars agreed with Shisui. 

"As for enlightenment... boy, there are many, many ways to attain it, yours, though somewhat special, is not rare by any stretch of the imagination. A farmer can attain enlightenment while plowing the field, a mother while cooking for her children, and a blacksmith while working with metal.

Contrary to what people may think, enlightenment is nothing more than being aware of yourself and your place in the cosmos. Enlightenment manifests in many ways, and yours is connected to spirituality because you are a sage.

What better wisdom for a sage than to know everything about himself, including all his past lives? If you don't know yourself, you can't be a true sage," Wan patted Shisui's shoulder, making the young man pout. 

Wan was very strong for his age, but his words cleared Shisui's doubts. Yes, his enlightenment was different from Aang's in the original series, Korra's or Zaheer's.

All four were enlightened but in different ways. Aang's allowed him to maintain his emotions and Avatar state, and even better understand energy control.

Korra's made her more human and aware of her limitations, but still allowed her to achieve perfect union with Raava. Zaheer was the most drastic, shedding all his doubts, and all his attachments, and rising above everything he once was, allowing him to fly and manipulate the air as if it were an extension of himself. 

Shisui's enlightenment had to do with knowledge, a very deep recognition of himself, his past lives, and his present self. If he were to return to the real world, he would realize that he could now make life flow much more easily than before and that he seemed to be in a perpetual state under the influence of the full moon. 

No, even now, his gift, something that had followed him from his last past life, had undergone a fundamental transformation. It was simply a different way of seeing the world that no longer caused as much fatigue as it did when one's eyes were naturally tired. 

It even allowed him to see more detail than before, because if it had been an hour ago, he wouldn't have been able to see the strangeness in Aang or the similarity between the Avatars. Shisui took a deep breath before sitting down on the ground and looking at all the Avatars in front of him. 

"What are you waiting for? Sit down, I have to be back by tomorrow," Shisui said with a smile on his face, and for some strange reason, the Avatars felt something strange. 

They felt like naughty children being caught by a tutor. 

"Oh yes, about that... you will stay here for a while, but don't worry, so many Avatars here change the time flow of this place, when we are done, it will only have dawned on the earthly world," Wan said suddenly, as if he had forgotten a small detail. 

"Won't my spirit age because of that?" Shisui asked annoyed, but Kuruk was the one who answered. 

"No, the only one who will age is Aang, he is the one who needs to mature properly for his current body. Since the day we manifested in the earthly world, his body has been growing slowly, partly because of the loss of his vital essence. 

This appearance was dangerous for him, it strained his mind to a level we did not expect, perhaps because of the time he was trapped in the ice, and we partly regret that, that is why we make all this effort for the boy, he does not deserve it. 

Come to think of it, if everything fits, Aang will be about 18 or so when he wakes up" Kuruk's words made Shisui frown, something about it didn't sit well with him.

"Is Aang destined to wake up or something?" the idea of destiny and things like that made Shisui very uncomfortable, that's why his tone sounded a bit angry. 

"No! You don't understand the time flow of this place, let me explain better," Kuruk said, noticing Shisui's misunderstanding. 

"Except for certain fundamental places, the spiritual world is not synchronized with the real world, when you come out, you will find that only one night has passed, but Aang will wake up 2 years later, but for him, it will be shortly after your awakening. 

So for two years, you will know nothing about Aang, but for him, it will only be a few moments. All this has certain consequences, like, in a strange way, some spiritually active people will be attracted to the place where Aang lies, especially because his chi is floating around," after this explanation, Shisui understood better. 

The spiritual world was something like the Disformity, but without the bullshit of this place, and except for a shudder on Shisui's part when he made this association, there was nothing more important. 

Thus began Shisui's teaching of Aang, forcing him to study science, especially mathematics. If Aang were to become the most powerful being in the world, he would not be an uneducated boy, and Shisui would be ashamed to be his teacher. 

He taught him without prejudice about everything that had happened since Aang disappeared. The actions of the Fire Nation, the extermination of almost all the Air Nomads, the war. Sure, Aang was angry, sad, and resentful, especially when he learned that Shisui was part of the Fire Nation.

But Shisui taught him history, about what had happened in the future, about how the war had wreaked such havoc on the world, but that he was essentially part of humanity, for better or worse. 

It taught him about the changes that had taken place in the last century. About science, and philosophy, and even Shisui learned about the Air Nomad way of life and some of the things Aang wanted to teach him.

Of course, this didn't change Aang's final resolution to end the war, but the way he wanted to do it was no longer just to target Ozai directly. He wanted to work more deeply with all nations, to make war not the first option, but the last. 

Aside from Aang telling him strange stories about how he could hear the voice of a young girl who was always talking to him, telling him stories about life at the South Pole, Shisui taught Aang his philosophy about chi and the elements. 

Aside from the discussion they had about how strange, cruel, but beneficial blood bending could be for humans, Aang was able to grasp some of the basics that Shisui wanted to teach him about how to take his element further, to the essence of it. 

He taught him that they were not only a means to affect physical phenomena, but also to touch spiritual or mystical aspects. Especially the element of air, which was the freest and most spiritual of the four elements. 

When water flows, the wind is unbound. According to this concept, Aang was "freeing" himself from the gradual loss of vital elements, which was damaging both his body and his mind. 

A strange approach, but it allowed Shisui to see what he already knew, that all the elements came to the same point from different paths. Each element was independent but dependent on the others, they were unique but contained traces of the others. 

The last confirmation he needed was from an Airbender, and with that, Shisui felt that perhaps he could try to better control the humidity of the air by applying some of the philosophy of that element.

Aang even told him that he could try to use his control of air to heal wounds and even purify spirits like water does when it comes out of the ice it is trapped in. That's another thing, the two became friends, with their differences, but friends. 

They told each other about their lives, Shisui about growing up in the Fire Nation and fighting in the war, and Aang about his childhood and his doubts about being the Avatar.

The strange voice became more and more frequent in Aang's ears, and it even seemed that the boy who had taken a liking to the person talking to him while he was frozen had an idea of who it might be. 

If there was anyone who could be spiritual enough to be drawn to the place where Aang rested, it was Katara. The girl was a true waterbending genius, so Shisui, driven by a whimsical idea, taught Aang the basics of the element.

Sure, he couldn't bend water in the Spiritual Mute, but the basics were not only an introduction for the young Avatar, but a kind of icebreaker with Katara when he woke up. 

Time was strange for Shisui, it was as if he was always on the night of his enlightenment, while for Aang it was all so much longer. The young Avatar was slowly maturing, but Shisui knew that the young man's true maturity would come when he was truly free to explore this world. 

Shisui's relationship with the Avatars was slowly changing. So many stories from the past, so much lost knowledge and so much to learn from them, made Shisui endure the most annoying group of them in pursuit of continuous learning. 

He learned about the spirit world, the Harmonic Convergence, Vaatu, the spirits, and how this strange place worked. This last piece of information was important because there was one place Shisui had to go before leaving the spirit world. 

Shisui had to face the Mirror of Souls because he wanted to take a serious look at his soul and learn more about his essence. At some point, he felt that he had the knowledge he needed to go to that place with Aang. 

"Are you sure you want to come with me?" Shisui asked an excited Aang, who was frolicking around him. 

"Yes! Because this will be our first adventure together," Aang replied with a smile on his face, causing Shisui to shake his head. 

"But you know I'll be leaving after this, especially since you're almost healed, you've almost gathered all your scattered chi, right?" Shisui could see that Aang could have healed himself like that long ago, but he seemed to be holding it back for some reason. 

"I... look, you might be my only friend. The others are... well, you know, old, you're the only companion I have," Aang looked a little down at this point, but Shisui drew a smile that would make his friends cringe because it was obvious that he was going to annoy the Avatar.

"Don't you have a friend who always visits you and tells you about her life? Maybe she picnics next to the block of ice where you are, that's already a date, you know? She's really pretty, wouldn't it be great if they got married and you could bring back the Airbenders?" Shisui's words made the relatively innocent Aang blush with embarrassment.

"Hey, at least I'm not a guy who ignored a girl who was crazy about him!" Aang hit low, making Shisui grimace. 

"Well, I'm not stuck on ice," Shisui replied. 

"And I don't have such ugly taste in clothes! All your clothes are black? You don't have good taste," Aang replied. 

"I'm not bald," Shisui used his secret soul, but Aang just grinned. 

"It's a style I chose because, oh surprise, I have the accomplishments that my people can only get from those decrepit old men," Aang touched his tattoos with a mocking look on his face. 

His spiritual body had no hair on his head because his body was trapped in ice and not conducive to regaining his scalp, but Aang thought about it, he would let his hair down just to annoy Shisui. 

"The Avatars named me Sage," not knowing what else to say, Shisui flaunted his title. 

"I am the Avatar" Aang's argument was undoubtedly better, so Shisui remained silent. 

"And I am an enlightened one" Shisui's answer this time left Aang without a response, but then he nodded. 

"Yes, they say that fools become enlightened faster than others, only a fool who ignored the love of his life for as many years as you did was worthy of enlightenment" Aang's teasing was elaborate and made them both fall silent before bursting into laughter, even hanging on each other's shoulders as they did so. 

"I'm going to miss you after this," Shisui said somewhat reluctantly before looking off into the distance. 

There was a clear boundary between the zone created by the Avatars and the rest of the spirit world, and if they crossed it, they would only have a few hours to find the Mirror of Souls and then return to the real world. 

"Not me, I'll be busy meeting a pretty girl, though I can't believe her brother became a pirate to get her scrolls from the waterbenders, just because the ones at the North Pole refused to teach her more than just healing, I'll have to get even with those guys," Aang said viciously, causing Shisui to raise an eyebrow. 

Sokka is a pirate, that's an interesting development," Shisui thought before responding verbally. 

"I wish you luck, and if you can get me water from the spirit pond at the North Pole, it will come in handy," Shisui asked and Aang touched his chest before nodding. 

"You got it," Aang looked back to where all the Avatars were silently watching them, Shisui did the same. 

"So... let's start our little adventure," Shisui said before he and Aang set off. 

"Do you think it's a good idea?" Kuruk asked Roku, who just stroked his long white beard. 

"I don't know, but what I do know is that no one will bother those youngsters while we're here," Avatar Roku said before his eyes sparkled, as did those of the others. 

At that moment, the other inhabitants of the Spirit World, especially those who were powerful, received a clear message: don't get smart and just watch Shisui and Aang's adventure.

As Shisui passed through the barrier, he partially synchronized with his physical body, and many spiritually sensitive people looked up at the night sky and realized one thing, something that registered as the previous times this event had occurred in the past.

An Enlightened Being had been born!

--------------

AN: 1M views! OMG! And 8k collections! Lol, thank you for reading!

For those doesn't get it. When the 'plot' starts, the characters will be this ages:

Shisui: 20 years old. Zuko: 20 years old. Petra: 20 years old. Yue: 20 years old. Sokka: 19 years old. Mai: 19 years old. Suki: 19 years old. Aang: 18 years old. Azula: 18 years old. Katara: 18 years old. Ty Lee: 18 years old. Toph: 16 years old.

About the Spirit Realm: The time in it is strange and could be similar to the real world or could be faster or slower, only punctual places of this place have similar time to the real world.

Avatars can create a time-distorted zone, every great spirit can do it. Shisui senses that it needs only a few hours to find the Mirror of Souls because of the knowledge he learned from Avatars. Yes, he can go back to the real world, but he wants to find that object or place.
