Through the Mirror’s Path

Summary:

Stories rarely end the way we wish they would.
Sometimes the finale is predictable, sometimes it’s shocking — but there are also those that feel inevitable, as if written long before they began.

Fate is never merciful.
At times, it merely offers the illusion of choice, letting you believe the fall can be avoided.

But what if everything was decided long ago?

**Warning:**
Volume One is a fully rewritten canon with minor alterations.
The beginning of Volume Two includes a brief summary of the first, after which the main story unfolds.

This work is based on the prompt:
*After the Snap, Thor goes back in time.*

Chapter 1: 1.1. The Voice of Destiny

Chapter Text

 


“It should have been the head,” Thanos said, his voice low and devoid of emotion.

Thor froze. Stormbreaker grew heavy in his hand; his fingers clenched around the hilt until it hurt. His breath came raggedly. Before his eyes, the scene blurred—the Titan slowly raising the gauntleted hand, the gleam of the stones, his fingers about to snap.

“No!” Thor roared, lunging forward—but it was too late.

SNAP

A dull, short sound, yet it rolled through the air like thunder. The world went still. Even the wind seemed to stop. Thor stood amid that terrible silence, not understanding what had happened. Thanos was gone, but something in the air had shifted—an unseen tremor that made his heart lurch.

He turned, instinctively sensing disaster. Out of the corner of his eye, he saw movement—Wanda, staggering to her feet after the blast. Their eyes met for a fleeting second. Then horror dawned in hers.

Her fingers reached out toward him—before her body began to crumble into dust.

“Wanda…” he whispered hoarsely.

In an instant, she was gone. Only a trace of ash drifted away on the dying wind.

“No… no, no…” Thor breathed, looking around in panic.

Another warrior vanished. Then another. They were all turning to dust—faces frozen in fear, in pain, hands reaching for help that would never come. Thor stood helpless, paralyzed, trapped in a waking nightmare. Stormbreaker slipped from his grasp and struck the ground with a dull thud.

“I… did this?”

The thirst for vengeance that had fueled him drained away. In its place—emptiness. A crushing, hollow pain. All he’d wanted was to avenge Asgard. To avenge Loki. But instead—he’d doomed half the universe.

The image of his brother’s final moments flashed again before his eyes. Loki, sacrificing himself for him—for one last chance to win.

Thor clenched his jaw and fell to his knees. His fist struck the ground with a muffled crack, but there was no release. The world around him dimmed. Sound faded into a distant hum, as though reality itself was dissolving. Somewhere deep inside him, something vast and ancient stirred.

He felt his mind falling—into a void.


There was nothing. No light, no sound—only a suffocating emptiness. Thor rose slowly; even that simple motion felt wrong, like moving underwater. The air was thick, heavy. Each breath burned.

“Where… am I?”

No answer. Only silence.

He felt despair rising in his chest. Everything had gone wrong. Everything.

He’d sworn revenge—for Loki, for everyone he’d lost. He’d forged Stormbreaker for that single purpose. He’d faced Thanos—and failed.

The snap had been so brief, so simple. Yet it had ended worlds. Faces, dust, silence.

If only I’d aimed…
If only I’d thought, instead of charging in like a fool…

He closed his eyes—but the visions didn’t fade. Loki’s body on the floor of the ship. Frigga. Odin. All of them gone. And now half the universe with them. He’d failed again.

But then—something flickered ahead. Tiny points of light, glimmering faintly through the mist. Like stars in fog.

He began to walk. Slowly, painfully. Each step dragged through resistance, but the air grew thinner, easier. The fog thinned. The stars brightened. And soon he felt snow crunching beneath his boots. The world returned—pale and cold.

On a distant hilltop, he saw it: a small wooden cabin, golden light spilling softly from its windows.

Thor hesitated, listening. Only the whisper of wind replied. He didn’t know why he was drawn to it—only that he was.

He climbed the hill. Frost clung to the door like ancient lace. He raised his hand and knocked. The sound echoed strangely, swallowed by the stillness. For a moment—nothing. Then the door creaked open by itself.

Warmth met him. The glow of a hearth. But the air inside was unnaturally still, heavy with a presence older than time.

Three women sat by the fire.

One was young, her golden hair loose and shining, her eyes bright with curiosity.
The second, a woman in her prime, calm and strong, her gaze both steady and knowing.
The third—old, her face marked by the deep lines of centuries, her eyes sharp as blades, as though they saw through the fabric of the world.

Thor stopped. A shiver ran through him—not from cold, but recognition. He knew, instinctively, these were no mortals.

The eldest rose. Her movements were slow but commanding.

“Welcome, Thor Odinson,” she said, her voice echoing like it came from the bones of the earth itself. “We have been expecting you.”



Thor stood before the three women, feeling a strange tension coil inside his chest. He studied each of them carefully. Their faces were different, yet something bound them together—an unearthly stillness, ancient and absolute. Their presence stirred something in his memory: the old tales of those who weave the threads of fate.

The Norn Sisters.

He straightened quickly and bowed his head in respect.

“Ladies of Fate,” he said solemnly. “It is an honor to stand before you. Yet I do not understand why you have called me. I have failed everyone—my friends, my people, my family. I am guilty as a brother, as a son, as a king, and as the protector of the Nine Realms. I fulfilled none of my duties.”

He lifted his gaze again.
“You must know this. So why me?”

The three Norns exchanged silent glances. Urðr watched him with a gaze so piercing it made him want to look away. Skuld, the youngest, smiled faintly.

“We have chosen you, Thor Odinson,” Verdandi finally said, her voice calm and deep, flowing like a river. “You have been summoned for a great task—one that will change the fate of Asgard and the Nine Realms. If you succeed, you will save your family, your people, and earn the chance for redemption.”

Skuld stepped forward, her tone sharper.
“But if you fail, all will perish. Not just Asgard—everything. The entire universe will fall beneath the weight of the fate you yourself helped shatter with your arrogance and blindness.”

The words struck Thor like lightning. His fists clenched, but he held back from answering.

“Each being has more than one path,” Verdandi continued. “What your destiny becomes—for you, and for those bound to you—depends on the choices you make. You still have a choice.”

Hope flickered in his chest.
“So… you mean,” he hesitated, his voice uncertain, “things could have been different—if I had been wiser?”

Skuld nodded softly, her eyes full of quiet understanding.
“Yes. It could.”

“Different,” Verdandi added, “does not always mean better. Or worse. It depends on you.”

Thor’s jaw tightened, and his eyes burned with resolve.
“I will do whatever it takes to make things right. I swear it.”

The Norns shared a long, knowing look. Then Urðr stepped forward.

“We can grant you that chance,” she said, her voice deep as distant thunder. “But the road will be hard, and the price—great. You will become a voice within your younger self: the voice of reason, the voice of conscience. You will see all that is to come, but your words—your power—will be limited. You may not speak of the future. You may not touch or speak to anyone but yourself.”

Her gaze hardened, merciless.
“The time you remain there will depend on Loki. He is the knot that binds Asgard’s fate. His life is the key to all things. His pain, his choices—every thread connects to the Nine Realms. You will draw strength from his life.”

Thor’s breath caught. His fate—again tied to Loki’s.
Images flashed before his eyes: not of the enemy Loki became, but of the boy who had once walked beside him, laughed with him, dreamed with him. He had never seen the loneliness beneath the mischief. How many times had he let the others mock him? How many times had he dismissed his brother’s hurt as nothing?

He remembered their mother—her warmth, her voice urging them to stay united. She had believed in both of them. And he—he had failed her too. If Loki had been free that day, perhaps they could have saved her. Heimdall. Odin. All the lives lost. All because he’d turned away—because he hadn’t seen how deep his brother’s pain ran.

Anger and grief burned in his chest.
He would not let Loki suffer again. Never.

Verdandi stepped closer.
“If your brother becomes aware of your presence—if he feels you near—he will die that instant. Fate will not suffer interference. A single mistake, a single wrong step, and his death will seal yours. Without Loki, your soul will scatter to the wind. You will vanish from all time and space.”

Skuld’s voice softened, though her words were no less dire.
“You will be forced to watch as he walks the path he chose. You will see his pain, you will feel it—but you will not be able to help. You may only change yourself. Break that law, and all will be lost—your life, and his.”

The echo of their words filled the silence like a tolling bell.
Thor’s throat went dry. He thought of Loki—his fall into the void, his alliance with the Chitauri, the endless quarrels, the pain. It had all begun there… If only he had seen him then, truly seen him, everything might have been different.

There would have been no invasion of Midgard. No deaths. No Ragnarok.

There is no other way, he told himself. I can’t keep running from my mistakes. Everyone who trusted me is gone because I was blind and proud. It cannot happen again. If I can change even one thing—I must try. For Loki. For Mother. For all of them. I let fate break me once. Never again.

“I accept your terms,” he said quietly, but his voice cut through the silence like a blade. “Even if it costs me my life. Better death than watching them suffer once more.”

The Norns exchanged one last glance, as if reading more in his words than he knew.
Urðr raised her hand. The fire roared, spilling silver light across the walls.

A portal opened in the center of the room—shimmering, radiant. Asgard gleamed beyond, untouched by grief or ruin.

“You have chosen your path, Thor Odinson,” Urðr said. “Now go. And remember: fate lies in your hands.”

Thor clenched his fists, braced himself—
and stepped into the light.
