The Fire Nation ruled over the Water, Earth, and Air, for many years. Its rule was met with little to no resistance from the Tribes. Thanks in large part to the Royal Fire Nation Family that ruled over the Capital.

Fire Lord Azulon ruled the Capital for many years. Along with him was his son, Prince Ozai, his daughter in law, Princess Ursa, and his grandchildren.

Grandson Zuko

Granddaughter Azula

And his third grandchild.

Zairon or as he affectionately called "Daikon" by his mother, Ursa as it seems she preferred to call him "Daikon" than his real name. Zuko and Azula would later refer to him as his nickname, both silently agreeing it fits him better than Zairon. But soldiers and their subjects refer to him as "Zairon".

Little did Daikon know that his nickname has a meaning that will be his fate in his family, the Nation, and the world.

"The Flame Beneath the Stone"

While Zuko is the more shy and clumsy, also yearning for their father's approval, Azula is cold and calculating, earning most of her father's praise and is favored by him, Daikon's more... quiet. Calm. As if he's neutral to everything around him but his silence brings comfort and understanding.

The Fire Nation would make rumors about his stare... a stare that can pierce through any fire in front of him.

"That's Prince Zairon... the quiet one. He never says much, but when he looks at you, it's like your soul forgets how to lie."
– Market woman outside the palace walls

"The younger prince never plays, never laughs. He just watches. I think he sees more than any of us were ever meant to."
– Temple groundskeeper sweeping the courtyard

"You don't salute Zairon because of his title. You salute because his silence leaves no room for disrespect."
– Veteran palace guard during a changing of the watch

"I've never heard him yell. Not once. But I'd rather be scolded by Fire Lord Ozai than get that stare from young Zairon."
– Royal guard after witnessing a disciplinary stare

"Most kids spark too early or burn too bright. Zairon burns... inward. That's the kind of fire you can't control."
– Military trainer observing royal children's bending practice

"Zairon listens more than he speaks. And when he speaks, it's as if he already weighed a hundred versions of silence."
– Court philosopher during a lesson debrief

"He doesn't ask questions. Not because he doesn't care—because he's already asked himself, and the answers frighten even me."
– History tutor after a lesson on Fire Nation war campaigns

"He never interrupts. Never jokes. Never wanders. That kind of focus in a child isn't natural—it's terrifying."
– Fire Sage instructor to a colleague

"Zairon says nothing, and still they listen. That kind of power doesn't come from blood... it comes from something deeper."
– Azulon, quietly to Iroh after a war council

"He is fire that does not flicker. That's what unnerves them. He doesn't crave attention—he commands it by doing nothing at all."
– Azulon, watching Zairon sit silently during a royal banquet

"Ozai thinks strength is in the voice. But Zairon... he carries strength in silence. And that, my dear Iroh, is the kind that shapes empires."
– Azulon to Iroh in private

"If he ever decides to speak—not scream or shout, but speak—the whole world will hear it."
– Azulon's final comment after watching young Zairon leave the throne room

Of course it's misinterpreted, but it also holds truth. Whenever Azula or Zuko make a lie, Daikon with give them a stare that makes them tell the truth.

Daikon mostly draws the moments around him. Even to the point of accuracy as his siblings and mother wondered how got every detail. However, he was not known for training or fire bending.

It got to the point many believe he doesn't know how to fire-bend. Though it gets drowned by Azula always telling people off to defend her brother. Which is very uncharacteristic of her as she always mocked Zuko, yet she acts playful to Daikon but never mocks him.

One day, Daikon is seen drawing something from his head while Azula and Zuko argued as usual. Daikon, or Zairon, simply draws with no care in the world.

Kid Azula: You're such a baby, Zuko! You cried when Mai's doll lost its head!

Kid Zuko: It was your fault the doll broke! You tied it to a firecracker!

Kid Azula: Oh please, I was testing trajectory. It's called science—maybe try learning something.

Kid Zuko: You're so full of yourself! You act like you're smarter than everyone else—

Kid Zairon: If two Komodo rhinos argue in the garden... all the flowers would die.

This stopped Azula and Zuko arguing as they turned to their little brother, surprised to hear him speak while also confused.

Kid Azula: What does that mean?

Kid Zuko: What rhinos?

Kid Zairon: Both of you.

He resumes drawing. The sound of charcoal scratching against parchment fills the quiet. Azula and Zuko exchange a glance. Neither has a retort. A breeze moves through the trees. In the distance, a palace servant stifles a laugh.

*much later*

Ursa calms for them as they receive word from their Uncle, Iroh. He was at the walls of Ba Sing Sei, preparing to lay siege. He has sent gifts to his Nephews and Niece. A Pearl Dagger for Zuko, a Doll for Azula, and a Dragon Pendant for Daikon.

Daikon held it with pride but remained calm and neutral.

*later*

They siblings would learn the tragic news of their cousin, Lu Ten, passing in battle. Zuko sits stunned, Azula folds her arms with a strange, unreadable expression. Zairon simply lowers his head, eyes closed in quiet mourning.

*later*

Later, as Zuko practices clumsily with his dagger, Azula mocks him for his lack of skill and dedication.

Kid Azula: You're wasting time playing with knives. It's not like you're any good with them.

Kid Zuko: Leave me alone, Azula!

Kid Azula: By the way, Uncle's coming home.

Kid Zuko: Does that mean ... we won the War?

Kid Azula: No, it means Uncle's a quitter and a loser.

Kid Zuko: What are you talking about? Uncle's not a quitter!

Kid Azula: Oh yes he is! He found out his son died and he just fell apart! A real general would stay and burn Ba Sing Se to the ground, not lose the battle and come home crying.

Kid Daikon looks at Azula with a stare.

Daikon: Enough.

Azula freezes. His rare interjection and steady gaze silence her immediately.

Soon, Ursa arrives and spoke to them.

Ursa: Your father has requested an audience with Fire Lord Azulon. Best clothes, hurry up!

Zuko runs off as Azula walks slowly. But before she spoke, Zairon grabs her wrist and pulls her away with Ursa watching.

Ursa: Seems he knew what she's going to say.

The scene changes to the Fire Lord's chamber, a large room with many columns and a wall of fire in front of the Fire Lord's throne. Ozai, Ursa, Zuko, Zairon and Azula are all sitting on the floor some distance back from Fire Lord Azulon, though Ozai's face remains obscured save for his mouth.

Ozai: And how was it Great-Grandfather Sozin managed to win the Battle of Han Tui?

Kid Zuko: Great-Grandfather won ... because ...

Kid Azula: Because even though his army was outnumbered, he cleverly calculated his advantages. The enemy was downwind and there was a drought. Their defenses burned to a crisp in minutes.

Ozai: Correct my dear. Zairon?

Zairon nods as he remains silent.

Ozai: Now, would you show Grandfather the new moves you demonstrated to me?

Azula stands up and moves forward. She begins with some circular motions, warms herself up, and firebends. Ozai smiles. Azula does many fairly complicated moves with ease, and Zuko watches her in amazement. She finishes off her routine with a jump and a powerful fire blast toward the throne, before landing on her feet gracefully.

Ozai: She's a true prodigy! Just like her grandfather for whom she's named.

Azula sits back down and looks at Zuko.

Kid Azula: *whispers* You'll never catch up...

Kid Zuko: *stands up angrily* I'd like to demonstrate what I've been learning.

Ozai frowns at this news. Zuko starts off well, doing the same circular motions as Azula earlier. He manages to produce a small fire blast, which does not impress Fire Lord Azulon. When he tries to create another one, he falls. He gets back up, panting heavily, and tries again, only to fall harder. Ursa gets up worriedly and approaches Zuko to comfort him.

Kid Zuko: I failed.

Ursa: No. I loved watching you. That's who you are, Zuko. Someone who keeps fighting even though it's hard.

Zuko sat down as Azulon spoke to his third Grandson.

Azulon: Prince Zairon. Do you have something to demonstrate me?

Ozai: *hesitant* Pardon, my Fire Lord, but Prince Zairon has never committed to training like Zuko and Azula. For that, I-

Zairon soon stood up and walks to the front of the hallway. Everyone looks on in confusion.

Zuko: *whispers to Ursa* What is he doing, mother?

Ursa: I don't know, Zuko.

Soon, Daikon took a deep breath and breathes out through his nose, as smoke comes out of the holes. He then opens his mouth as it glows and... he breathes fire... but not any kind of fire.

Everyone was shocked. Prince Zairon has breathed fire, but not just any fire, purple fire. Something that no one has seen or reached. Only Azula reached Blue Fire, but this fire was controlled, beautiful, and unnaturally intense.

Azulon: What in the spirits?

Ursa: He... he breathes fire...

Azula: But purple?

Zuko: How? He never trained with us...

Ozai: This power... it could rival battalions. He could destroy entire legions on his own.

Zairon simply returns to his seat, folding his hands in his lap as if nothing occurred. He does not acknowledge their stares, does not speak.

The silence that follows is heavier than before, the weight of his potential pressing down on everyone in the room.

Soon, Azulon dismissed them except Ozai. Zuko and Azula stayed behind while Ursa and Daikon walked together.

Ursa: You didn't tell anyone you could do that.

Zairon doesn't respond at first. He looks ahead, eyes steady, not cold—but withdrawn.

Ursa: Not Zuko. Not Azula. Not even your father. Why?

Zairon: ... Because it didn't feel like something I needed to show... until now.

Ursa stops walking. Daikon takes one more step before pausing beside her.

Ursa: You taught yourself?

Zairon: In secret. Before sunrise. After curfew. Whenever no one was watching.

Ursa looks at him carefully. There's no pride in his voice—only quiet honesty.

Ursa: Why hide the color of the flames?

Zairon: *looks at her* Because it's different. And different is... dangerous.

Ursa's eyes soften. She steps closer and knees down, putting her hand on his cheek.

Ursa: Your fire isn't dangerous because it's purple, Daikon.
It's dangerous because of how much control you have over it. Because you chose not to use it. That... is what makes it powerful.

Daikon's expression doesn't change—but his shoulders ease slightly.

Ursa: Purple flame isn't a curse. It's a mark of your spirit.
Rare... beautiful... and born from balance. Not rage. *places a hand on his chest* Whatever this power is, it's yours. But it doesn't define you. You do.

Zairon slowly nods. The lantern light flickers in his eyes.

Zairon: ... Thank you mother.

*later*

Daikon is seen drawing before going to sleep. Soon, Azula enters her room. He looks at her but noticed a face he never thought to see... panic and determined.

Azula: Come on. You'll be staying in my room for tonight.

Daikon tilts his head in confusion but Azula grabs his arm and pulls him off his bed.

Azula: Come on. They won't find you there.

She pulls him away as they entered her room. The reason why Azula is acting this way is because she heard that her grandfather and father arguing about Ozai taking his brother's place as the next fire lord after Lu Ten's death. Azulon was enraged and orders Ozai to sacrifice one of his own sons so he could feel what Iroh felt.

Azula doesn't know if Ozai would choose either Zuko or Daikon, but she's not taking chances with Daikon being the choice. So she brought him to her room to sleep there to hide him.

But then, the next day, Azulon was found dead. No one knows why, but tragically... Ursa was gone. Ozai took control as the New Fire Lord but Zuko, Azula, and Daikon were heavily affected by their mother's departure.

*2 years later*

Time has passed since Ozai took over and Ursa was gone. Around this time, Zuko attended a meeting with generals, Ozai, and Iroh about a trap for a siege in Ba Sing Se.

When one of the generals present suggested sacrificing a division of novice soldiers to lure Earth Kingdom soldiers into a trap, Zuko protested, prompting Ozai to challenge him to an Agni Kai as a means to settle the matter. Zuko wrongly assumed he would face the general whom he had spoken out against, when in reality he was facing his father because although he had spoken against the general, he had dishonored his father in doing so. 

Daikon is seen in front row during the Agni Kai. His grew a bit taller and his hair has grown longer. But he looks on with worry for Zuko. Behind him was Admiral Zhao, Azula and Iroh looking on as well.

Zuko begs for mercy as he tries to ease his father's wrath but Ozai doesn't listen and demands him to fight.

Zuko: I won't fight you.

Ozai: You will learn respect...

Zuko pushes himself up on his knees and hands.

Ozai: and suffering will be your teacher.

Zuko looks up at Ozai, tears streaming down his face.

Daikon looks on with horror as he tries to yell for Zuko to move away.

Soon the sound of a fire blast is heard, Zuko screams "no", which echoes the room. Iroh looks away as Zhao looks on with a smirk on his face, while Azula smiles and raises her left fist in front of her chest in anticipation.

But then, Daikon climbs up as he runs to Zuko who lays on the floor, holding his scared eye.

Daikon: Zuko! I'm here! *holds him tight* Breathe, brother! Breathe!

Ozai looks on before walking over to his sons with a growl of annoyance.

Ozai: Leave him, Zairon. *grabs Daikon's shoulder* He's not-

Suddenly, Daikon grabs Ozai's wrist, stopping him. Everyone looks on in shock as Daikon sat there, frozen. But the people looking at his face began to shake in fear as his neutral, worried, face, twists into a calm glare as he turns his head at Ozai.

Daikon then twists Ozai's wrist, as his father grunts, his eyes wide, teeth clenched. His wrist is bent at an unnatural angle.

Everyone froze as Daikon rises. Slow. Controlled. Eyes locked on Ozai.

Then—

A single punch.

Into Ozai's gut.

The floor buckles, splitting beneath them.

Flames around the ring vanish instantly—snuffed out by the sheer shockwave of impact.

Ozai drops to his knees, coughing blood.

Zhao stares, pale. Azula's mouth hangs open. Iroh is still, but his hand lowers from his mouth—he's seen a ghost rise.

And then—

Purple fire erupts. The once warm, controlled, and strong flames replaced with the Violet, intense, and wrathful fire of Prince Zairon.

Everyone feels it—not heat, but fear.

Ozai tries to rise, one eye wide with rage—but before he can speak, Daikon grabs him again—this time, by the neck.

Daikon presses his palm to Ozai's neck—purple fire flares, searing the flesh.

Ozai screams, louder than Zuko had. Everyone couldn't believe what they're seeing. The Fire Lord is being scarred by his own son. Daikon shoves him away, the Fire Lord rolling across the broken stone floor.

Daikon soon turns to Zuko and helps him up.

Daikon: I'm here, Zuko.

He walks. Past the shattered flames. Past the silence. Past the fear.

Not a single voice tries to stop him.

The arena doors close behind him with a thundering echo.

Ozai rises slowly, shaking, blood staining his robes, a fresh burn sizzling on his throat.

He limps out of the arena—silently, humiliated.

The room is dead quiet.

Until the murmurs begin. Whispers. Of what just happened. Of the silent prince who burned the Fire Lord.

*years later*

Two years has passed. Zuko accepted his banishment despite Daikon's protest. He sets out to find the Avatar with Iroh following suit though it's a clear case of failed task. Azula and Daikon remained at the Capital, but Daikon has been busy.

Now, at the age of 15, Daikon was well known, not just for his gaze, but his compassion yet quiet aid. He also helps around the city, despite guards, people, and advisors telling him not as he's the Prince.

His clothing is also distinctive as instead of the red uniform, it's purple and his hair is longer with a ponytail, making him unique and stand out from his siblings.

One day, while Azula left to find Zuko and Iroh while also searching as news of the Avatar being alive spread. Daikon stays silent in this, though does something no one would know until later.

Daikon is seen at the Fire Nation Capital Prison as he meets the warden.

Warden: Prince Zairon. *bows* What could we do for you?

Daikon: I need you to bring me some prisoners from the Earth and Water Tribe that can bend water and earth.

Warden: Very well, my prince... but what for?

Daikon: It's none of your concern, Warden. It is something I have planned.

Warden: I see. Though I must warn you, these prisoners would be dangerous without Guards.

Daikon: ... *nods* There's a forest far south of the Capital. I'll be there while you tell the Soldiers escorting the prisoners where to go.

Warden: Very well. How many do you want?

Daikon: Five prisoners. The ones with experience in Earth and Water Bending. *turns and walks away* That will be all.

Warden: Understood. I'll get them ready.

Daikon: And Warden... warn the guards of harming the prisoners. If a new burn or bruise I see, and I will know... they wouldn't be walking or breathing again.

Warden felt a shiver down his spine as Zairon walks away. Soon, he goes to the guards and does as the Prince commands.
