Maximum Warhammer Effect Ch. 1.

Well, this is a first for me.

Mass Effect x WH40K FIC(ONE SHOT-for now). Let's goooo.

An Astartes finds himself thrust into the universe of Mass Effect. Are they ready for one of the Emperor's greatest warriors? Hahahahaha...I think not.

Chapter 1: Through the Maelstrom

Brother-Sergeant Maximus Thorne had known turbulence before. Drop pods were coffins of steel hurled through fire and fury, and he had ridden them into warzones since his ascension to the ranks of the Adeptus Astartes.

He knew the groaning of ceramite under stress, the bone-shaking judder of atmospheric entry, the animal pull of gravity that crushed even a transhuman frame. These were familiar things. Predictable. Conquerable.

This was not.

The pod screamed as though daemons clawed at its skin. The descent vector fractured; warning runes flared scarlet across his retinal display, and the grav-stabilisers failed with a shriek of tortured metal. Then came the light—sickly, shifting, colors that hurt to perceive. His enhanced vision parsed forms where none should be: leering visages pressed against the void, too close, too vast. Their mouths moved but the words burrowed directly into his skull, a cacophony of temptation and blasphemy.

—Why fight, little son of man? Lay down the burden. The galaxy burns regardless—

Thorne’s auto-senses cut to silence as his Litanies of Hate rolled across his memory implants. His voice joined them, iron and absolute, roaring through the claustrophobic pod.

“The Emperor Protects! I am His wrath made manifest! I am His will against the storm!”

The voices receded, but the pressure did not. Warp fire licked the edges of his vision, burning across the pod’s slats, yet leaving no mark. Time stretched—seconds drawn to hours—as he plummeted through unreality.

Then, as violently as it began, it ended.

The pod slammed into earth with a thunderclap, tearing a crater into alien soil. Restraints snapped free, the retro-burners coughing sparks before dying. The pod’s ramp blew outward in a roar of pneumatics, and Thorne strode into a world not his own.

The air was wrong. Clean, but not Imperium clean—no tang of recycled atmosphere, no cloying incense of Mechanicus scrubbers. Fresh. Verdant. Almost… soft.

Above him, a sky stretched unmarred by the choking haze of industry or the thunder of battlefleets. Fields of unfamiliar crops swayed in the wind, and hills rolled toward a horizon dotted with scattered farmsteads.

No vox-chatter greeted him. No orbital telemetry scrolled across his helm. The tactical uplink to his battle-brothers returned only static.

Isolation struck colder than the drop itself.

He thumbed a rune on his vambrace. His bolt rifle mag-locked into his hands, chambering with a thud of blessed engineering. The weapon was comfort, anchor, reminder: he was Astartes. Alone perhaps, but never lost.

A rustle broke the silence. Low shapes darted between the crops. Thorne turned, weapon raised.

The creatures that burst forth were quadrupeds, wolfish but alien, eyes glimmering with animal hunger. They encircled him, growling, teeth like shards of glass. He allowed himself one measured breath.

Then the first leapt.

The bolt rifle roared. A single round blew the beast into ruin, detonating mid-body in a thunderous blossom of gore. The others balked, then lunged in a frenzy. Thorne moved like a fortress given motion: a sweep of armored arm broke a spine, a stomp pulped another. His power sword flashed to life, edge crackling as it cut one beast cleanly in half. In less than thirty heartbeats, the pack was shattered, broken bodies strewn across the field.

Silence returned, broken only by the hiss of his blade powering down.

And then—voices. Human, this time.

They emerged cautiously from the farmstead: men, women, unarmored, clutching primitive-looking weapons of metal and plastic. Their eyes widened as they beheld him—eight feet of ceramite-clad war-god standing amid carnage.

“Holy… stars above…” one whispered. Another dropped his rifle, crossing himself with a sign Thorne did not recognize.

The Astartes remained motionless, rifle lowered but ready. His helmet vox filtered his words into a rumbling thunder.

“Identify yourselves. What world is this? What banner do you serve?”

They flinched at the sound. One, braver than the rest, stepped forward. “Eden Prime,” he said, voice wavering. “Colony of the Systems Alliance. We—we’re human, same as you.”

Alliance? No Imperial titles. No echoes of the Emperor. No recognition of his chapter.

The realization carved ice into Thorne’s gut.

Still, he suppressed the rising tide of suspicion. These were human. Flesh of Terra’s line, however far flung. That alone demanded protection.

He deactivated his helm’s seals with a hiss and lifted it free. His scarred face and piercing eyes met theirs. Gasps rippled through the crowd at the sight of a man beneath the armor.

“Then you are kin,” he said. His voice, without the helm, was iron softened by conviction. “Fear not. No harm will come while I stand.”

Relief mingled with awe across their faces. Some bowed their heads; others only stared, as though beholding an angel or a monster.

Thorne felt the weight of their gazes, and the isolation deepened. These were his people, yet they were not. Humanity had spread to the stars without the Imperium. Without the Emperor.

He clenched his jaw. Questions clawed at him—When am I? Where has the Imperium gone?—but answers would come later.

For now, a sound cut across the wind: distant explosions, rolling thunder from beyond the hills. Smoke curled upward on the horizon.

The civilians turned, faces blanching. “What was that?”

Thorne replaced his helm, voice once more a resonant growl.

“War.”

And with a warrior’s certainty, he strode toward the rising fire.

The colonists shouted after him, voices breaking with fear. Some begged him to stay, to protect their families; others urged him not to go near the attack. Thorne did not slow. His stride carried the weight of destiny, servos whirring within his Gravis armor as he marched toward the smoke.

They did not understand. He could no more ignore war than a star could refuse to burn.

He moved with unnatural speed across the fields, his bulk devouring distance. Every sense strained outward—autosenses swept infrared, auspex arrays pinged for signals, his genetically-enhanced hearing parsed the echoes of distant battle. Explosions cracked like thunder, punctuated by the shriek of weapons fire.

Yet the patterns were wrong.

These were not las-bolts, not the chatter of autoguns or the solid thud of heavy stubbers. The cadence was alien: pulses of energy, sharp staccato bursts, mechanical precision. And woven through it all, a sound that chilled him—synthetic modulation, inhuman voices barking in perfect unison.

Not daemons. Not Orks. Not Eldar. Something else entirely.

Cresting a ridge, he saw them.

Machines.

They moved with the unity of a drilled regiment, yet with none of the vitality of living soldiers. Angular bodies of metal and light, faceless visors glowing with cold intelligence. They advanced through the colony outskirts, cutting down defenders with disciplined bursts of fire. Civilians fled screaming, their weapons useless against the invaders’ armor.

Thorne’s instincts categorized them at once: xenos abominations.

And yet—his mind, trained to war since youth, noted the precision of their coordination. No rage. No hesitation. A machine warband, wielding alien weapons, against which the colonists stood no chance.

He raised his bolt rifle.

The first round left the barrel with the thunderclap of a miniature cannon. It tore into the nearest construct, detonating its torso in a blossom of fire and shrapnel. Metal shrieked; fragments scythed through the air.

The second shot smashed another’s head-unit to ruin.

Panic rippled the machine phalanx. They shifted with mechanical efficiency, adjusting fire toward him, but he was already moving. Armor servos howled as he advanced downhill, each stride a seismic thud. Their return fire lanced against his shields, brilliant flashes across his visor. Alarms flared, but the Gravis plate held.

A grenade arced from his gauntlet, landed amidst the enemy. The detonation hurled three machines skyward, limbs twisting in fire.

The colonists behind him stared, dumbstruck, as the war-god waded into the storm.

One of the machines broke through the smoke at close range, weapon raised. Thorne met it head-on. His power sword ignited in a snarl of energy, shearing the construct in half with a single downward stroke. Sparks cascaded across the ground, the severed halves twitching before collapsing inert.

He stood amidst wreckage, chest heaving with the rhythm of combat.

More were coming. He could hear their marching, feel the tremor of their advance. The battle was not over—it was only beginning.

Thorne reloaded his rifle with a fresh mag, the sacred mechanism clunking into place. His voice rumbled through the vox, low but certain:

“So be it. If war has come to this world, then it will find me ready.”

And with that, he strode into the fire.
