The raw bone needle glided smoothly through the seal-pelt leather, binding the hilt-wrap with practiced precision.
Kaelen sat on a sun-bleached driftwood log near the village watchtower, his steady hands paring down the edge of a custom whalebone knuckle-guard. The Arctic wind whistled off the frozen tundra of the Southern Sea, biting and merciless, but he barely felt the chill.
Fragmented, shadowy memories stirred deep within his mind—flickers of glowing blue blueprints, the precise biomechanics of joint locks, and odd, broken snippets of a story. He knew vague, outline-level details of a narrative: an Airbender frozen in ice, a scarred prince hunting him, a long journey north, and a war spanning a hundred years. But the details were blurry, like trying to recall a dream long after waking up. Names, exact dates, and tactical particulars escaped him. He didn't have a cheat sheet; he just had a faint sense of where the tide of history was turning.
He tightened the grip on his double-edged trench blade and gave the steel a crisp click back into its leather sheath.
"Kaelen!"
A soft voice broke his focus. Kaelen looked up, his pale, off-white eyes catching the pale sunlight.
Two village girls, Sura and Naya, were walking past carrying baskets of dried kelp. They slowed down, their eyes wandering over his bare arms—completely unbothered by the sub-zero wind—and the easy, confident air he carried.
Kaelen didn't need to say a word. He simply raised an eyebrow, gave them a smooth, lazy smirk, and offered a subtle nod.
Sura flushed deep crimson, giggling into her sleeve as she bumped into Naya, both of them practically stumbling on the ice before hurrying along with excited hushed whispers.
Kaelen chuckled quietly under his breath, sliding the dagger into his belt.
"I don't get why you spend so much time making handles pretty," a sharp voice grunted from the snow path.
Sokka marched over, dragging a wooden paddle and struggling to adjust a clumsily fitted shoulder guard. At fifteen, Sokka was all frantic energy, loud ambitions, and sharp elbows, desperate to be taken seriously as a warrior.
"A knife is only as good as the grip, Sokka," Kaelen said smoothly, his quiet, grounded voice cutting through Sokka's nervous rustle. "If your hand slips half an inch when you parry, your fancy strike fails instantly."
Kaelen reached into his parka and tossed a polished bone cylinder to his younger brother.
Sokka caught it clumsily. "What's this?"
"I re-balanced the centerpiece on your boomerang," Kaelen replied, standing up and adjusting his own fur tunic. "And I packed you a smoked sea-prune wrap with roasted garlic roots for lunch. Don't let Katara knock it into the ocean."
Sokka opened the container, caught the rich, savory aroma—light-years ahead of the bland boiled blubber the rest of the village survived on—and his eyes went wide.
"Kaelen... you are a legendary genius," Sokka breathed, instantly popping a piece into his mouth. "Dad left the wrong guy in charge of food."
"Dad left me in charge of keeping you two alive," Kaelen said gently, stepping close to adjust Sokka's loose shoulder strap with one quick, expert pull. "Which starts with nutrition and gear that doesn't fall off."
"Hey! Are you two coming or what?"
Katara stood near their small fishing canoe at the edge of the ice shelf, her arms crossed over her parka. At fourteen, she carried the weight of the household on her shoulders, ever since their mother Kya died in the raid seven years ago.
Kaelen's gaze softened when he looked at her. He was ten when Kya was killed. Unlike Sokka, who remembered warm, faint comfort, Kaelen remembered the exact smell of ash, the sound of iron boots, and the bitter truth that he hadn't been strong enough to stop it.
Never again.
He knew from his vague plot fragments that Katara was destined for greatness as a waterbender, but right now, she was defenseless in a dangerous world. Kaelen kept his own waterbending completely hidden, even from her. To the tribe, he was just a master hunter, a brilliant craftsman, and a lethal hand-to-hand fighter. But in absolute secret, he spent his nights refining his chi flow, internal body control, and precision strikes.
"We're coming, Katara," Kaelen called back, his tone warm and reassuring.
An hour later, their small canoe glided through a silent graveyard of towering blue glaciers.
Sokka stood at the bow, spear poised dramatically to catch fish. Kaelen sat in the middle, guiding the boat with minimal, efficient paddle strokes, his eyes scanning the ice walls.
A quiet nagged at the back of Kaelen's mind. An iceberg. A boy. An accident on the water. The fuzzy memories told him this routine fishing trip wasn't going to end with fish.
"Steady, Sokka," Katara whispered from the stern. "You're going to scare them."
"I know what I'm doing!" Sokka hissed. "It's all about calculated precision..."
A sudden, aggressive current surged beneath the hull, slamming a heavy ice floe straight into their port side.
"Look out!" Katara shouted.
Sokka panicked, swinging his paddle wildly against the ice. "I've got it! I've got it!"
"Sokka, stop—" Kaelen warned, but Sokka's wild strokes jammed the canoe right between two massive ice sheets. Hydraulic pressure groaned through the timber, snapping the side ribbing with an ugly CRACK.
"Left side, jump!" Kaelen commanded, his calm demeanor instantly shifting into absolute authority.
Sokka and Katara leapt onto the flat ice shelf just as the canoe crumpled and sank into the dark depths.
"Great! Fine! Way to go, Sokka!" Katara exploded, throwing her hands in the air. "You sank our only boat!"
"Me?! You were the one backseat-driving my fishing!" Sokka yelled back.
While the two started their usual back-and-forth shouting match, Kaelen walked quietly to the edge of the ice floe. He didn't waste breath arguing. Instead, he slowed his breathing and focused.
Underneath his eyelids, the subtle veins around his temples twitched.
Byakugan.
His vision inverted instantly. Color washed away, replaced by vibrant lines of structural stress, thermal heat, and flowing energy. Through the ice and sixty feet of freezing water, Kaelen looked down.
Deep beneath the surface, a massive, hyper-dense sphere of compressed elemental energy was rising fast. The raw chi radiating from it was staggering—luminous, ancient, and overwhelming.
So the plot memories were real, Kaelen realized, a faint, sharp thrill running through him. The Airbender is right down there.
"Quiet, both of you," Kaelen said smoothly, placing a firm, grounding hand on Sokka's shoulder.
Sokka and Katara went silent at once, sensing the shift in Kaelen's posture.
"Kaelen? What's wrong?" Katara asked, eyeing his pale, intense gaze.
Before he could answer, the ocean boiled. A massive surge of pressurized air burst from the sea, shattering the ice around them as a colossal, glowing sphere of solid blue ice broke the surface, rising high into the sky like a newly born moon.
Inside the glowing ice, Kaelen's visual sight locked onto two distinct life signatures: an enormous, six-legged beast, and at its center, a small boy with arrow markings, radiating an impossible concentration of raw power.
Katara gasped, stepping forward in awe. "There's... someone in there!"
Kaelen deactivated his vision, letting his eyes return to normal as he reached down, unlatching his trench dagger with a calm, expectant smirk.
"Sokka, stay behind me," Kaelen murmured softly. "Our ride out of the South Pole just arrived."
