10 FALL OF THE MOON
━━━━━━
He gritted his teeth and pushed forward.
Every instinct told him to move faster, to reach the ship and his Uncle before the Fire Nation or anyone else could discover their position.
But the wind was relentless, folding over itself, obscuring the horizon.
Each step was a struggle against nature itself.
After what felt like hours of walking, the world became a blur of white.
Zuko's vision narrowed, his body trembling from exhaustion.
Ahead, a darkened depression in the ice hinted at shelter—a small cave, likely carved by centuries of frost and wind.
Relief hit him like a wave. He ducked inside, snow blowing after him, and staggered to the floor, leaning against the stone as his chest heaved.
The cave was narrow, but the walls were thick and offered some protection from the storm's teeth. Zuko let out a long breath and eased Aang down carefully. The Avatar didn't move, didn't stir, but the small weight of him sliding against the ice reminded Zuko how heavy responsibility could be.
Zuko sat, and began rubbing his hands together before pressing them against his cheeks and neck to fight the cold.
His cloak was damp from snow, his gloves stiff, and even the heat simmering beneath his skin seemed to falter against the Arctic bite.
He tugged his hood over his face and hunched his shoulders, trying to gather warmth from what little fire he could summon inside.
For a while, he simply remained on the icy floor, praying for the blizzard to subside before he could continue on.
The storm outside screamed, but within the cave, he was shielded enough to think, to breathe, to consider.
Every thought twisted back to the Avatar—small, impossible, powerful even in unconsciousness.
Every move, every breath, every decision he had made to this point had led him here.
And yet, the weight of his previous failures pressed heavily against him.
His exile. The relentless expectations of his father.
The shame that had branded him as unworthy of his people and the throne.
He had taken the Avatar, yes—but taking him was only the first step.
He had to protect him, transport him, and survive a blizzard that seemed determined to test every ounce of his resolve.
He drew his knees in and rested his forehead against them, breath fogging the space between. Pain throbbed through every muscle, a dull, constant ache he had long since learned not to fight.
Pain was familiar.
Pain could be endured.
The fire in his chest still burned.
That was what mattered.
Time stretched. The wind raged on, but inside the cave it dulled to a distant roar, as though the world beyond the ice had been muted. Zuko hunched closer to the stone, coaxing heat from deep within himself, rationing it the way he rationed everything else—strength, breath, resolve.
Waiting was its own kind of trial.
His thoughts drifted, unbidden, to the waterbender.
He didn't know the man's name.
That in itself was irritating.
He remembered the way he'd stood—too composed for a common guard, too deliberate in his movements.
The cut of his stance had been trained, disciplined, nothing like the desperate flailing of villagers defending their homes.
And his presence—quiet, commanding—had shifted the fight before it had even begun.
Zuko frowned.
Water Tribe, clearly. But not a soldier.
A noble, perhaps. A chieftain's son. Some kind of prize.
That would explain the confidence. The way he hadn't flinched beneath fire or fury. The way he had looked at Zuko as if weighing him, rather than fearing him.
It grated.
The man's face lingered in his thoughts—windburned, sharp-eyed, framed by ice and motion. Not smug. Not cruel. Simply... certain. As though Zuko's rank, his ship, his purpose meant nothing beyond another force to be met head-on.
They had clashed, and for a heartbeat—just one—Zuko had felt it: the unsettling certainty that he was being measured.
Judged.
He forced the thought away and reached instead for the familiar. The ship. The creak of its hull beneath his feet. The order of its deck. The single presence aboard who had never turned away from him, even when the world had.
If he could reach it—if he could deliver the Avatar to his Father—then this would all mean something. The pain. The cold. The waiting.
And yet the memory of the waterbender lingered, stubborn as frost.
A reminder that no matter how far north Zuko ran, there were still those who would stand their ground and look him in the eye.
"I will not fail." He murmured, the words barely more than breath. Not a promise to his father. Not a plea for forgiveness.
A vow—to himself.
The fire beneath his skin answered, faint but steady.
Outside, the blizzard surged again. Ice rattled against the cave mouth, snow skittering across the floor. Zuko instinctively shifted towards the Avatar.
It grounded him.
Reminded him why he was here.
Every scar he carried whispered the same truth: he had endured before.
The cold.
The waiting.
The silence.
All of it was just another test.
Then—
Without warning, it happened.
A light, immense, blinding, impossible—erupted from the body of the Avatar.
Not pale moonlight, not glints of ice, but a single, focused beam, cutting through the white haze like a blade of silver and gold.
It seared across the horizon, illuminating the ice fields, painting shadows and snowdrifts in stark, brilliant clarity.
Zuko froze, pulse hammering in his chest. The light was unmistakable. Alive. Commanding attention.
His heart leapt—not in relief, but in the raw surge of urgency.
Every instinct screamed at him to move, to protect, to reach the boy.
The ship could wait, the storm could wait—this was the signal, the marker, the proof that Aang's presence had not been hidden.
The light carved a path through the storm, unwavering, undeniable.
Zuko slung Aang's small form onto his back once more. "We move." He muttered, more to himself than anyone else. "We survive. We reach him."
He straightened, fire coiling just beneath his skin, and pressed forward toward the mouth of the cave. Snow and wind lashed at him, but the path was clear. The beam of light awaited, guiding, demanding, impossible to ignore.
And Zuko ran.
━━━━━━
The wind was brutal at that altitude.
It shrieked past Hai's ears, tore at his cloak and lashes alike. The North stretched endlessly beneath them — white on white on white — broken only by jagged ice ridges and the dark veins of frozen water cutting through the land like old scars.
Hai leaned forward, one hand gripping Appa's fur, eyes narrowed against the glare.
"There." He said sharply, following the beam of light that was the Avatar.
Katara followed his gaze.
At first it was just movement — a dark shape fighting its way across the ice, staggering, slowing, pushing forward anyway. Then the shape resolved into something unmistakable.
A boy.
No.
The firebender and the Avatar.
Katara's breath caught. "That's—"
"Zuko," Sokka said, already halfway out of his seat. "That's definitely Zuko."
Yue stiffened beside them, fingers curling into Appa's saddle. "He's barely standing."
Hai felt something cold and sharp settle in his chest.
The firebender moved like someone who had already passed his limits and refused to acknowledge it. Each step was uneven. His shoulders shook. The storm tore at him mercilessly, snow swallowing his boots almost as fast as he pulled them free.
And still, he didn't stop.
"He's not going to make it," Katara said. "Not like that."
"Good," Sokka snapped. "Let him drop."
Hai didn't answer.
He was watching the way the firebender adjusted his grip — careful, almost gentle — the way he angled his body against the wind to shield the smaller one on his back.
That detail lodged itself somewhere unpleasant.
"Appa," Katara said urgently. "Down. Now."
Appa roared, banking hard as he descended. Wind screamed louder, snow exploding upward as his massive paws hit the ice in a thunderous impact that sent white spraying in every direction.
The firebender skidded back, barely keeping his footing.
He looked up.
For a split second, their eyes met.
Recognition flashed across his face — sharp, furious, exhausted.
And then he turned and ran.
"Oh no you don't," Sokka said. "You do not get to run again."
Hai was already moving.
He hit the ground running, boots biting into ice, breath ripping painfully from his lungs. The firebender was fast — faster than he had any right to be in this storm — but exhaustion betrayed him. His stride faltered. His balance wavered.
Hai closed the distance in seconds.
"Put him down." Hai commanded over the wind.
Zuko didn't answer.
Didn't slow.
Didn't even look back.
Fine.
Hai struck.
The water answered him instinctively, surging up from beneath the ice in a sharp, controlled burst. It slammed into the firebender's legs, sweeping them out from under him.
He hit the ground hard.
Aang slid free, rolling across the ice before Katara caught him, skidding to her knees and pulling him close.
"Aang," She said urgently. "Aang, can you hear me?"
The firebender pushed himself up with a snarl, fire flashing briefly in his hands — weak, sputtering, furious.
Hai didn't give him the chance.
They collided like opposing tides.
Hai drove forward, relentless, every movement precise and merciless. Water lashed, struck, wrapped. The firebender fought back on instinct alone, fire snapping and flaring but never quite finding its mark.
He was strong.
He was skilled.
He was done.
Hai swept his legs again, slammed him back-first into the ice, then brought his a torrent of water down hard against the side of the boy's head.
The firebender went still.
Silence rushed in, broken only by the storm and Appa's low, uneasy rumble.
Katara looked up, eyes wide. "Hai—"
"I know," He said, already kneeling. "I know."
Aang stirred in her arms.
His eyes fluttered open.
"Katara?" he murmured. "Why is everything... spinning?"
Katara laughed weakly, pressing her forehead to his. "Because you scared us half to death."
Aang blinked, then frowned. "Where's—"
He spotted Zuko unconscious
"Oh," He said. "Him."
Hai stood slowly, staring down at the boy on the ice.
Up close, he looked younger than Hai had expected. Sharp features softened by exhaustion. Burned. Bruised. Teeth clenched even in unconsciousness, like his body hadn't learned how to rest.
Sokka crossed his arms. "Okay. So. We leave him. Right?"
Katara nodded immediately. "We can't take him with us. He kidnapped Aang."
"He would die out here." Hai said quietly.
"Good." Sokka shot back. "That's not our problem."
Hai didn't look at them.
Sokka groaned. "Why is this even a conversation?"
Hai knelt and hauled the firebender upright, slinging larger man over his shoulder.
"Because," he said calmly, "I'm not letting the North take another life tonight."
Katara stared at him. "You're serious."
"Yes."
"You're unbelievable."
Aang shifted, leaning weakly against Katara. "He... didn't hurt me," he said quietly. "He just... ran."
That settled it.
Sokka threw his hands up. "Fine. Great. Bring the enemy. I'll just add it to the list of terrible ideas."
Appa rumbled as they loaded both boys onto his broad back — Aang carefully supported, Zuko unconscious, frost already clinging to his lashes.
As Appa lifted into the air, the storm swallowed the ground beneath them.
Clouds folded in on themselves, thick and bruised, the wind biting harder as Appa pushed forward. Snow streamed past in frantic sheets, swallowing the land beneath them until the North became an endless blur of white and shadow.
They didn't speak at first.
Aang leaned heavily against Katara, eyes half-lidded, exhaustion dragging him back toward sleep now that the danger had loosened its grip.
Yue sat close, one steady hand resting against Appa's saddle, her gaze flicking constantly to the horizon as though she could already sense something shifting there.
Hai focused on Zuko, slung across the back of the saddle.
He was still unconscious, breath shallow but steady, dark lashes crusted with frost. His hands were bound loosely with rope for now, wrists red and raw from the cold.
Not enough.
He placed his hands around the Zuko's wrists, water drawing instinctively from the air, condensing into a thin sheath of ice. The motion was practiced, precise—cold curling in smooth bands around skin and rope alike.
The ice sealed with a soft crack, locking his hands together like crude cuffs.
Katara watched, jaw tight. "Thank you—"
Before she could answer, Yue inhaled sharply.
They all felt it then.
A pressure, sudden and wrong, like the air itself had tightened around their lungs.
Hai's head snapped up.
The moon—full and bright only moments before—had begun to change.
Red bled across its surface, slow and unmistakable, as though something unseen had reached up and stained it from within.
Katara's breath hitched. "That's not—"
Yue was already standing, eyes wide, luminous skin paling. "The balance." She whispered. "Something is wrong."
Katara's face drained of color. "I can't feel it."
Sokka blinked. "Can't feel what?"
"My bending," Katara said. Her voice shook now. "It's gone."
Yue pressed a hand to her chest, breath shallow. "The moon," she said. "The moon spirit—something has happened to it."
As if in answer, the moon deepened to a sickly crimson, casting the world below in warped, blood-tinted light.
Aang stirred, sitting up straighter. "Katara?" He looked around, confusion sharpening into alarm. "Why does it feel... quiet?"
Hai swallowed.
The ocean inside him—vast, constant, familiar—had fallen silent.
Not pulled back.
Gone.
"We need to go back to the Oasis," Yue said, urgency cutting clean through the wind. "If the moon spirit is in danger—"
"Then the whole Water Tribe is too." Hai finished.
