For untold ages, the Nine Realms had known order. That order bore the name Asgard.
Under the rule of the All-Father, Odin Borson, the realms were watched, weighed, and when necessary corrected. Empires had risen in defiance and fallen to ruin. Monsters born of ancient hatred had crawled from forgotten dark places, only to be broken beneath Asgardian steel. Even betrayals from within
kin turned against kin had been met with judgment swift and absolute.
Thor, heir to thunder.
Loki, once prince, once shadow.
The Warriors Three.
The Valkyrie.
For thousands of years, they had been the spine of peace. Even Loki's treachery wounding the heart of Asgard itself had not shattered that spine. The realms bent, but they did not break and order endured.
Until Vanaheim began to burn.

VANAHEIM – THE GREEN REALM
The sky was wrong. That was the first thing Fandral noticed as he spun his blade clean of blackened blood.
"This sky," he said sharply, eyes narrowing, "has never known fire. I've fought here before Vanaheim breathes mist and sunlight, not flame." Above them, the heavens were torn open.
A vast rift was there and it was bleeding, it split the clouds like a wound that refused to close. Shadow poured from it in rolling waves. Fields of harvest lay trampled beneath armored feet.
Hogun stood unmoving, sword resting on his shoulder, his eyes fixed on the rift.
"This is no simple breach," he rumbled. "The Vanir were right to call for aid."
Volstagg, panting heavily as he wiped ichor from his beard, let out a humorless laugh.
"Call for aid? They should have called for the end of feasts and the beginning of funerals! I have cleaved that one—" he pointed behind him at a twitching corpse "—twice! And yet it still crawled toward me like it wished to taste my boots!"
The corpse behind him shuddered… and then stood.
Its armor was ancient and older than Asgardian forging, etched with sigils that glowed a dull, hateful red. One arm hung uselessly, cleaved nearly in half, yet it raised its weapon all the same.
Fandral cursed.
"Oh, that is deeply unpleasant." Hogun moved without hesitation. One brutal strike removed the creature's head entirely. The body collapsed finally still.
For now.
"They do not retreat," Hogun said grimly. "They do not fear death."
Volstagg scowled.
"I have faced Frost Giants, even dragons drunk on their own arrogance. All bled. All screamed. These things however?" He shook his head. "They ignore pain."
Fandral sheathed one blade, gesturing toward the sky.
"And more arrive every moment."
From the rift, ships descended. The looked like jagged vessels of dark metal, their hulls humming with alien power. As they touched ground, ramps lowered, releasing more of the rabid soldiers.
The Vanir lines were breaking.
Vanir warriors, the masters of nature and magic were being pushed back, cut down, overwhelmed by sheer numbers.
"This began as a skirmish," Fandral said tightly. "A border disturbance. Nothing more."
Hogun's voice was iron.
"Now it is war." A group of Vanir sorcerers stood in a widening circle, staffs raised, runes burning in the air between them. They chanted, voices strained, sweat pouring from their brows as they attempted to seal the rift.
The air screamed in protest and the rift resisted.
One of the sorcerers cried out as energy lashed back, throwing him across the field. Another fell to his knees, blood running from his nose.
Volstagg swore loudly.
"By the mead halls of Odin, they're killing themselves trying to close it!"
Fandral clenched his jaw.
"The energy required is immense. Far more than a natural tear should demand."
Hogun stepped closer with sharp eyes.
"Because it is not natural."
The rift pulsed and another ship descended.
Volstagg slammed his fist into his shield.
"They are reinforcing through it! Whatever opened that thing planned this!"
Fandral laughed once, sharp and bitter.
"Planned? My dear Volstagg, this has been prepared. Look at their armor. Their formations. This is no raid."
He turned, meeting Hogun's gaze.
"It's an incursion."
Hogun nodded slowly in agreement.
"One that is growing stronger."
Another wave hit them as the blades rang. Lightning cracked in the distance where Thor battled elsewhere in the realm, but even thunder did not thin the tide fast enough.
Volstagg roared as one of the creatures slammed into him, sending him skidding through mud and broken roots.
"I crushed your chest!" he bellowed as he rose. "You should be dead!"
The creature lunged again.
Fandral intercepted it, blades flashing.
"They adapt," he said breathlessly as steel met steel. "Each wave lasts longer and can take more punishment."
Hogun struck down two foes in rapid succession, but even as they fell, others climbed over their bodies.
"They are learning," he said. "Or being adjusted."
Volstagg growled.
"Well then whoever is adjusting them needs a good hammer to the skull!"
Another ship descended.
Then another as the rift widened again.
Fandral looked up, dread creeping into his voice despite his usual flair.
"There is no end to them… is there?" Hogun did not answer immediately as he also watched the terrifying sight.
When he did, his voice was low.
"No."
A horn sounded amongst the Asgardian soldiers and it caught his attention.
Reinforcements had arrived, but even they looked small beneath the torn sky.
Volstagg leaned on his shield, breathing hard.
"We have fought many battles," he said quietly. "But this…" He gestured to the burning fields, the unending enemy. "This feels different."
Fandral nodded.
Hogun turned his gaze toward the rushing wave, eyes hard as forged steel.
"Then Asgard must respond in kind."
He lifted his blade.
"We hold the line. We buy time. And we warn the All-Father."
Volstagg grinned grimly.
"Good. Because if this is truly an incursion—"
Above them, the rift thundered wider cutting him off and Vanaheim burned.
The Vanir fought with everything they had for days upon days. But Vanaheim was a realm of life, not endless war.
Its magic flowed toward growth and renewal toward rivers that healed, forests that remembered, winds that carried seed and song. Against an enemy that did not tire, did not fear, did not die easily… that magic began to fail.
Most of their villages fell, their sacred groves which was older than Asgard's first wars were trampled beneath iron boots and alien flame. The rivers ran dark with ash and blood, and the sky itself seemed to recoil from the violence inflicted upon a realm that had never been meant to endure such ruin.
Then, The heavens cracke as the Bifrost tore open the sky in a pillar of blinding color.
"The Prince! The Prince has come!" Lightning slammed into the earth.
Mjolnir struck the ground and the ground obeyed sending out shockwaves that rippled outward, hurling invaders from their feet as the sky shattered with roaring thunder. Storm clouds coiled like living things above the battlefield, electricity ripping through them in wild, glorious arcs.
Thor Odinson stood at the center of it all, his red cloak snapping behind him, eyes burning with power.
His voice rolled across the field like a war horn.
"STAND FAST, PEOPLE OF VANAHEIM!"
"ASGARD STANDS WITH YOU!"
A roar answered him from the Vanir and Asgardian alike.
More Bifrost beams slammed down as reinforcements arrived. There were shieldmaidens, Einherjar, hardened warriors laughing in the face of doom as they charged headlong into the fray.
Volstagg was already knee-deep in the enemy when Thor arrived, cleaving through one of the creatures with a shout of savage joy.
"Hah! You picked a fine time to join the feast, Prince of Thunder!" Volstagg bellowed, hacking another foe in half. "I was beginning to think you'd miss all the fun!"
Thor laughed, smashing two creatures aside with a single swing of Mjolnir as he landed near them.
"From the look of it, Volstagg," he replied, lightning dancing along his arms, "you've saved me the largest portion!"
Fandral appeared in a blur of steel and motion, blades flashing as he danced between enemies, every movement elegant and infuriatingly effortless.
"Oh, do try not to break all of them before I'm finished warming up," he called lightly, parrying and riposting. "Some of us enjoy a challenge."
Thor grinned, eyes scanning the battlefield as he crushed another attacker beneath Mjolnir.
"Report," he commanded. "What does it look like?"
Fandral's smile thinned.
"Endless," he said. "They come in waves. Stronger each time. Mindless beasts, perhaps but someone is guiding them."
Volstagg spat blood and laughed.
"Aye! Mindless or not, they hit hard enough! I've killed the same-looking brute three times already!"
Thor turned to Hogun.
"Hogun?"
Hogun said nothing and Instead, he raised his blade and pointed.
Thor followed the gesture and his expression darkened.
The rift above Vanaheim was no longer merely open. It was now pulsing and vibrating.
Another wave poured out creatures spilling from the tear in numbers that made even seasoned Asgardians hesitate.
One soldier whispered with a hollow voice.
"There's… there's no end to them."
Fandral exhaled slowly.
"This is no longer an invasion," he said. "It's a flood."
Thor's grip tightened around Mjolnir.
"Then we answer it like a storm."
He twirled the hammer once, lightning spiraling around him as his boots lifted from the ground.
"Mindless beasts?" Thor said with a grin, eyes beginning to glow white. "Then let them learn what true power feels like."
Thunder exploded outward as Thor launched himself skyward, storm energy surging, clouds tearing apart to make way for him.
But before he could strike, another sound rang out.
A thunderclap so violent it blinded the world and the sky flashed red.
A second rift tore open intersecting the first and from it spilled a massive wave of purplish-yellow energy, screaming like a living thing as it tore through the air.
Thor's eyes widened.
"That is not—!"
He veered instantly, barely escaping as the energy wave crashed downward.
It engulfed the newly emerged horde.
And then it detonated heavily and swallowed the battlefield in light.
When it faded however, the creatures were gone.
Erased from existence.
The tear in the sky shuddered… and began to heal, reality knitting itself closed as though desperate to forget what had touched it.
A stunned, breathless silence was left behind afterwards.
Then all of a sudden a bolt of red lightning struck the earth. The impact was so loud and powerful that it felt as if it shook the realm.
Smoke and dust billowed outward, heat rolling across the battlefield in waves.
Volstagg squinted into the haze.
"By the All-Father…" he murmured.
Thor descended, landing beside the Warriors Three as soldiers cautiously approached the smoking crater.
"Stand back," Thor ordered.
As the smoke thinned, something became clear and it wasn't debris or a weapon.
It was a person.
A naked human from the looks of it, unconscious, body battered and bloodied. Cuts and bruises marked his skin, but even in that state, the fact that he had survived that was staggering.
Thor stepped forward slowly.
His breath caught in his throat in surprise at who it looked to be.
'That White hair'
Unmistakable.
"…No," he muttered.
The smoke cleared completely.
Thor's voice dropped to a whisper of disbelief and recognition colliding in his chest.
"Gojo?"
