It had taken a lot of convincing, even by Asgardian standards.
For days, Harry had found himself caught between the will of gods and the weight of his own determination — every conversation another battle, every argument another test of endurance. And the goal? A single expedition… to a moon of Jotunheim, the seventh one, known only to Loki.
The great hall of Asgard was alive with murmuring voices. The royal family gathered—Odin on his throne, Frigga at his side, Thor and Loki standing like day and night at either end of the chamber.
Harry stood before them, shoulders straight, face calm but heart racing.
"I have to go," he said firmly. "If I'm going to work with Uru-Prime, I need to understand it at its source."
Thor folded his arms, looking almost proud.
"I told you, Father. He's not a child anymore."
Odin's gaze was sharp as lightning.
"You speak like one who does not understand danger. The moons of Jotunheim are not the forges of Nidavellir. They are ungoverned, frozen, wild."
Harry met his gaze without flinching.
"I know that. But if I'm to be your smith — Asgard's smith — then I must know my materials. You taught me that knowledge is the first weapon."
Frigga sighed, her voice soft but edged with worry.
"And yet, your knowledge often leads to danger, my dear child."
Harry's expression softened. "I'll be with Father and Uncle Loki. And the miners. And the guards. I'll be safe, Grandmother."
"Safe?" Loki drawled, smirking. "You do realize you're traveling to a moon made of deathly cold where I may have… provoked a few of the locals."
Thor shot him a look.
"A few? You nearly started a war."
"Yes, well," Loki said airily, "art requires a little chaos."
Odin's staff struck the ground with a thunderous crack, silencing them all.
"This is not a jest. If Harry goes, he does so under protection. Thor, you will lead the expedition. Loki, you will guide them."
Loki bowed with a dramatic flourish. "As the All-Father commands."
The next challenge was harder — explaining his departure to the people who cared most about him back on Midgard.
"You're leaving?!" Hermoine gasped. "For Jotunheim? That's insane, Harry!"
Draco looked less surprised, though his brows furrowed.
"Let me guess—some new Asgardian project involving danger, frost, and certain death?"
Harry grinned sheepishly.
"Just mining. That's all. We found a new type of Uru. I have to go study it."
Hermione crossed her arms. "For how long?"
"A month. Maybe two."
She threw up her hands. "You vanish for months at a time and call it studying!"
Draco, trying to mask concern with sarcasm, muttered,
"If you die, can I have your enchanted tools?"
Harry smirked. "If I die, you'll never find them."
Hermione's glare softened. "Promise you'll write."
"I can't exactly send owls through the Bifrost," Harry said with a grin.
"But I'll find a way."
He looked at them both.
"You two keep the theater project going. Hogwarts is finally learning what imagination means. Don't stop now."
They nodded reluctantly. Hermione hugged him tightly, and even Draco clapped his shoulder before looking away.
The night before departure, Harry stood on the royal balcony once more, looking up at the glittering stars. Odin joined him, his golden armor faintly reflecting the light.
"Do you truly understand what you seek?" Odin asked.
Harry nodded.
"I want to understand what makes Uru-Prime different. Why it hums like it's alive. Maybe there's a way to forge weapons that can protect without killing."
Odin's expression softened with pride and something older — the weight of eons.
"You remind me of someone," he said quietly. "A young fool who once thought wisdom could end war."
"Did it?"
"No," Odin said, looking at the stars. "But it forged peace for a time."
They stood in silence. Then Odin rested his hand on Harry's shoulder.
"Go, then. With my blessing. And may the light of the Bifrost guard your path."
At dawn, the sound of horns filled Asgard's skies.
The Bifrost opened in a torrent of rainbow fire.
Thor stood ready, hammer in hand. Loki adjusted his cloak with theatrical precision.
And Harry, now wearing his half-finished Thunderbird armor, stepped onto the platform.
He turned once, looking back — toward Frigga and Odin standing in the distance, their faces proud and fearful all at once.
Then the light took him.
The air howled. Space folded.
And when it unfolded again—
They stood on the ice of another world.
The descent to the seventh moon of Jotunheim was a plunge into stillness itself.
Even for an Asgardian, the cold was something alive — a creeping, biting presence that gnawed at armor and breath alike.
For Harry, who had camped on mountains and wandered through Alaskan storms, this was beyond comprehension.
He stepped out of the Bifrost's fading light and gasped.
Frost stretched to infinity — a silver desert lit by the pale glow of nearby suns.
The ice shimmered like glass, fractured and beautiful, and beneath it pulsed faint veins of faintly glowing blue.
Uru-Prime.
By the time the miners arrived, the place was a flurry of life and steel.
Dozens of tents were raised, runes carved into the ground to keep warmth in and frost out.
Massive furnaces, fed by coals, burned low against the wind.
But Harry, having come prepared, drew his own tent from his pack — the one Sirius had gifted him when he heard of the expedition.
He tapped the folded fabric with his wand and it unfolded itself,
stretching, expanding, reshaping until it became a sprawling, two-story pavilion of deep green canvas.
Warm air spilled out. The scent of cinnamon and polished oak drifted into the ice.
Inside were carpeted floors, a roaring fireplace, enchanted lanterns, and, to the astonishment of every Asgardian on the moon —
a hot-water shower.
Thor poked his head in first and whistled.
"By the Nine… is this a house or a tent?"
Harry grinned. "It's magic from Midgard. Sirius said it used to belong to his cousin who preferred luxury over logic."
Loki pushed past his brother, eyes wide. "Luxury over logic? I think I'm in love."
Before Harry could object, both gods had claimed the two big rooms, leaving him with the smaller one near the hearth.
When the other Asgardians saw the strange contraption of comfort, word spread faster than a lightning bolt.
Within the hour, miners and guards lined up to see the miraculous "Midgardian palace."
Harry stepped outside, hands on hips. "It's a tent, not a tourist attraction."
A dwarf with a braided beard huffed. "Then stop building miracles where people can see 'em."
Loki led the way to the ridge overlooking a frozen plain.
There, where the moonlight struck the ice at a sharp angle,
a lattice of shimmering blue veins glittered like rivers of starlight trapped beneath glass.
He knelt, brushing the frost away with one gloved hand.
"Here," he said softly, voice uncharacteristically serious.
"This is where I found it."
Harry crouched beside him, eyes narrowing.
The metal was beautiful — purer than any Uru he'd ever seen, humming faintly when his fingers brushed it.
It thrummed in harmony with his lightning-forged armor, as though it recognized kin.
"Uru-Prime," Harry whispered.
Loki smiled faintly. "Exactly what I thought. A metal that remembers. A gift from the first storms of creation."
Thor approached, hefting his hammer.
"And we shall forge from it weapons and armor worthy of legends!"
"First," Harry said, standing, "we mine it safely. If this metal carries life, we must not destroy what makes it so."
Thor raised a brow. "You talk like a dwarf."
Harry smiled. "That's a compliment where I come from."
By the third day, the miners had constructed a forge — an impressive structure of black stone and golden runes, its fire fueled by captured lightning.
Harry worked beside two dwarves, Master Hroldir and his apprentice, Nundra, who muttered constantly about "younglings with too much talent."
Hroldir inspected the first sample of smelted Uru-Prime and grunted.
"This… this be no ordinary metal. It bends runes that should not bend."
Harry took the hammer from him. "Then we'll learn how to make them sing instead."
They worked until the ice outside gleamed silver-white under twin moons, the sound of hammering echoing across the frozen plains like a heartbeat.
On the fourth day, Thor and Loki prepared to leave for Jotunheim proper, to meet King Laufey and formalize Odin's new mining treaty.
Thor adjusted his fur-lined armor. "Stay here, keep the forge safe. If anything happens—"
Harry waved him off. "I'll be fine."
Loki smirked. "You say that now."
They mounted their steeds — sleek Asgardian beasts that glided effortlessly through thin air — and rode toward the horizon, leaving trails of light behind.
Harry watched them vanish into the shimmering mist of the frozen horizon.
For a long time, he stood there, the icy wind whipping through his hair,
feeling both small and limitless beneath the stars.
The moon was silent, patient, watching.
And far below its frozen crust, something ancient stirred —
a whisper of magic, cold and old as the void itself.
For three days the moon had been nothing but a hammered bell of work and laughter.
When the sun of a distant world sank and the twin moons rose, the miners and smiths drew their cloaks close, lit their runes and braziers, and drank. The Asgardian liquor went down hot and wild; it loosened throats and shoulders and made the cold seem less like an enemy and more like a story to tell.
Dwarves traded bawdy songs for rocking laughs. A line of guards—stiff and competent by day—stomped their heavy-footed dances with surprising grace. Harry watched it all from the flap of Sirius's tent and felt, for the first time since leaving Midgard, the quiet swell of belonging.
He slept in a bedroll with a blanket he'd grown fond of; the tent smelled faintly of soot, the scent of the forge. When he woke, the sky glowed a hard, pallid blue. Outside, men and gods moved briskly—another day of mining.
It was the kind of peace that sings the loudest right before a blade falls.
The first sign was not a shout or a horn. It was the abrupt, unnatural quiet—an absence of laughter, a pause in the hammering. A line of Asgardian guards hurried across the plain, faces gone flint.
Harry stepped out of his tent just as the circle of shields and spears tightened around his little encampment. Men in furs, teeth bared and breath smoking in the frigid air, pushed forward and took positions at the perimeter. Swords flashed like new moons.
One of the captains—Broad-shouldered, beard braided with blue cords—was in Harry's face before Harry even knew he'd seen him.
"Prince," the captain said, voice low and hard as ice, "we are under attack. Frost Giants have come. They break the outer line. Men fall. You must be taken to safety."
Harry's eyes followed the captain's stare to the far horizon. A shifting wall of movement had risen where the glint of distant rock met the moonlight—shapes vast as houses, painted in frost: the Frost Giants.
"No," Harry said.
Harry half-turned, lifted his chin. The tent crackled. He felt the hum in his blood, the echo of hammers and lightning and the forge. He had spent nights and days shaping metal angry as storms, and for all the jokes and luxuries and warm water, the armor he'd conceived was meant for a night like this.
"I'm not going to hide like a coward while our men are being butchered."
He felt the ground under him like the palm of a hand and the word in his throat came steady. "I will lead the charge."
Around him something shifted—an intake of breath, the clink of metal as men reached for their weapons. The captain's eyes narrowed; then, with an expression that might have been pride or resignation, he said, "Then we follow you, Prince."
Harry lifted his hand and thought of the Bifrost—thought of the way Odin's armor had leapt to him in a flash of rainbow—and simply willed it. The air thickened. A high, electric whine threaded through the tent canvas, like a bow drawn across a harp string.
Light burst. In the blink of an eye the light gave shape—plates and filigree, wings of thunder snapping into being across his shoulders, two great tail-strands uncoiling behind him like living ropes of lightning. The armor fit like a second skin; runes sighed awake along the breastplate and the crow-etched chest flared. Heat stung the air, and for a moment the frozen moons seemed to hold their breath.
The guards drew close at his flanks; their faces, lit by the ghost-light of the armor, were set. Young miners, dwarves with soot still in their hair, and hardened Asgardian veterans took their places.
Harry turned slowly, looking at each of them. The wind tore a clean, cold line across his cheek and the armor answered with a soft electric crackle, wings flexing once.
"Listen," he said, voice rising to carry across the line of men. "They think we are cattle on their ice. They think this ground is free for the taking. Tonight we show them different."
A dwarf near his boot—Nundra, the apprentice—gave a short, barking laugh and pounded his fist on his chest. The captain drew breath and let out a shout, a sound that gathered the scattered courage of the camp and bunched it into a single, hot knot.
"Follow me!" Harry cried, and the word was a spear.
