Terra Aeterna: The Rise of Humanity's War Machine

The sea-born warriors of the Metkayina Na'vi charged through the waves with fierce determination, riding massive ocean beasts that shot through the water like living torpedoes. Their ancient war cries echoed across the vast expanse of the ocean.

"ULUULUULUULUUU!!"

"AAAHHHHHHHHHHHH!!"

Those primal screams pierced the heavens, as if tearing the veil between the spiritual realm and the world of flesh. Though armed with nothing more than spears and bows, not a single Na'vi showed fear. With unwavering resolve, they surged toward the RDA navy and the forces of the Celestial Imperium.

But…

They were not met by the silence of spirits—only the deadly blaze of incoming missiles. The roar of RDA choppers tore through the sky as salvos of rockets exploded from automated launchers. The once-blue heavens transformed into a hellscape of fire, metal, and smoke.

From the command bridge, Colonel Miles Quaritch narrowed his eyes at the oncoming charge.

"Those damn savages are at it again…"

With an unflinching voice, he gave the order.

Colonel Quaritch

"All stations, full alert. Open fire!"

Captain Mick Scoresby

"Attention all personnel! Fire at will! I repeat—fire at will! Do not let them near the ship! I repeat—DO NOT let the enemy get close!!"

RDA troops and Caelestis mechanized infantry scrambled into defensive positions. Steel doors slammed open, auto-rifles were loaded, and the ship's defensive systems activated within seconds. In the skies above, armed drones and mech walkers began to mobilize.

Then, the sea itself began to rumble.

TULKUN.

From the depths of the ocean, they emerged.

Massive, majestic leviathans—some over 80 meters long—rose between the waves like living warships. Their colossal bodies split the sea, each beat of their mighty fins conjuring tempests in their wake. On their heads, two hard, crown-like fins caught the sunlight, gleaming like the regal crests of ocean kings.

They were intelligent.

They were enraged.

One slammed its full weight into the side of a smaller RDA vessel. The reinforced steel folded like paper. An explosion tore through the air. Flames clawed at the sky.

Colonel Quaritch clenched his jaw.

"Goddamn sea fanatics… at this rate, our ships—"

But then, the world shifted.

The sky dimmed, as if the sun itself recoiled. Clouds blackened in an instant. The waves twisted into a massive vortex. And atop the main deck of the Sea Dragon, he appeared.

Kenthelion.

His body radiated blinding golden light—like a miniature sun descended upon the mortal world. Winds howled around him, coiling through his cloak. In his grip: a colossal sword, not aflame with ordinary fire, but burning with cosmic flame, drawn from the heart of Aetherion itself—a force capable of forging or erasing entire dimensions.

He gazed out over the sea—not with the eyes of a man, but with the gaze of a war god.

The ocean answered.

Waves raged.

Winds howled.

The sky boiled.

Then he spoke—his voice deep, resonant, echoing like a doomsday bell tolling from the void of the cosmos.

Kenthelion

"Colonel Miles Quaritch. Order your crew below deck. This is not a battle you are meant to witness—let alone interfere with."

His tone was calm, but the weight behind it bent the air itself. His golden eyes glowed brighter, and that same light began to spread across his entire being. In a flash, he was clad in the sacred armor of the Emperor of Mankind—not mere gold that reflected light, but divinity made manifest, radiating majesty and might.

His sword transformed, too—its cosmic blaze roaring like a newborn sun, ready to burn away the very concept of existence.

Now standing five meters tall, Kenthelion was no longer just a man.

He was the embodiment of humanity's supreme will.

Colonel Quaritch could only stare, eyes wide with disbelief. A veteran of countless battles, he knew without a doubt—the figure standing before him wasn't an ally, nor a soldier. It was an entity.

Without another word, he snapped into command mode.

Colonel Quaritch

"All personnel! Get inside the cabins and lock yourselves in! No one stays outside! That's a direct order!"

The crew moved instantly. Boots thundered across the deck, the sound of steel doors slamming shut echoing in rapid succession.

At the edge of the Sea Dragon's deck stood Kenthelion, gazing out at the now-frenzied ocean. The wind howled around him, lashing wildly. His hair—like strands of pure gold—whipped in the storm, and his eyes glowed like miniature suns, piercing the creeping darkness at the horizon.

Kenthelion

"I'll hold the front line. Protect this ship. Not an inch must fall."

He raised his colossal sword high. In an instant, the blade exploded with blinding light. One swing—and the sky and sea seemed to split. Waves that had never known fear recoiled as if the ocean itself bowed to a force beyond comprehension. Even the seafloor lay exposed, torn open like a raw wound in the planet's flesh.

Dozens of raging Tulkun never even had time to react. They were lifted, swept away, and vaporized into motes of light.

But the attack didn't stop the other sea beasts. If anything, it made them roar louder—charging without fear. Their eyes glowed a brilliant green—not from courage...

But because Eywa had spoken through them.

The atmosphere began to tremble. The skies over Pandora darkened—not with nightfall, but with the rising of a terrible force. Black clouds rolled in, and lightning danced on the far horizon like spectral serpents.

Kenthelion

"Entity that dares call itself a god... Show yourself. Or I will drag you from the depths with my own hands."

The sea beasts roared again.

Pandoran Sea Creatures

"Roar! Roar! Roar!"

Yet none of them stopped. They charged, one after another, without hesitation. Whether driven by courage or the will of the planet itself, their minds were no longer their own.

Kenthelion took a deep breath. The air around him pulsed, as if the world itself had paused to watch.

Kenthelion

"Even the will of the planet dares defy me? How... troublesome."

He lowered his sword—only to ready it once more, this time with lethal purpose. The aura around him swelled, shaking the entire deck beneath his feet.

Kenthelion

"Creatures born of Pandora's will—or what you call Eywa—

You dare to challenge the true will of humanity."

"Then I deliver upon you holy judgment—not because you are powerful,

But because your sins have surpassed the threshold of Absolute Truth."

"Feel a force not made for this world... but meant to end it."

"Let every strike be a warning...

And every blow the end of your mortality."

As his blade surged forward, the very atmosphere trembled. Every swing unleashed an unfathomable wave of Aetherion—pure energy born from the evolved will of mankind, transcending the boundaries of reality itself. The air howled with each strike, transforming into waves of destruction that tore through dozens of Tulkun at once, ripping them into airborne fragments of flesh, blood, and bone that scattered across the sea.

Yet even amid the celestial chaos...

Kenthelion

"Phew... enough already."

His lazy voice sounded almost like a sigh. The golden aura around him dimmed slightly as he exhaled, and that was the moment it had been waiting for.

A massive Tulkun—far larger than the rest—burst from the depths, its colossal body crashing forward with full force. It slammed into Kenthelion, pinning him against the deck under its immense weight.

The Sea Dragon's hull shuddered, but there was no time to panic.

Kenthelion didn't call upon holy power or cosmic incantations. He simply closed his eyes—and moved. Like a true swordsman. No flair, no theatrics. Just pure technique, passed down through embedded memory as the Emperor of Mankind.

One motion. One clean strike.

The Tulkun's body split cleanly from head to tail. Its reeking innards burst outward in a wet explosion, drenching the ship's deck and splattering across Kenthelion's golden armor.

Kenthelion

"Damn it... Time for a bath."

He raised his hand and sniffed the foul stench clinging to his armor with an irritated grimace.

Kenthelion

"Eywa... If this is the best you've got, I'm honestly disappointed."

The skies over Pandora roared in reply. But Kenthelion stood tall—not just as the emperor of mankind, but as a message to the entire universe:

Even the will of a planet... could be challenged.

And defeated.

Beneath the Ocean — Inside the Aquatic Terrain Armored Transport Convoy

Monk (Marine Force Commander):

"Attention, all units. We have one minute until strike point. Prepare yourselves."

Inside the pressurized underwater transport, dozens of Scuba Stormtroopers sat in tense silence, clad in white, waterproof armor. Each held a specially modified weapon—DC-17m Explosive Rifles and DC-12U Underwater Blasters—custom-built for brutal combat in deep-sea environments.

Monk:

"Status on AQ-Series Battle Droid units?"

Scuba Trooper 05:

"In position, sir. Standing by for combat deployment."

Monk:

"Good. Begin movement."

The marine units from each squadron sprang into action with military precision. Checking gear one last time, they exited the transport one by one, diving into the dark, high-pressure waters of Pandora's ocean.

Elsewhere — Shallow Waters Near the Metkayina Shore

Slicing through the water like torpedoes, the AQ-Series Battle Droids—ghostly machines shaped like shadows—charged forward. Engineered for warfare in extreme environments, their sleek bodies housed retractable laser cannons capable of eliminating targets both above and below sea level.

---

On Land — The Metkayina Clan Territory

Colonel Charlie, over the comms:

"Commence the assault. Landfall teams, wipe out all hostiles."

With perfect coordination, the AQ-Series droids and Scuba Stormtroopers broke through the surface simultaneously. No warning. No mercy. Blaster fire rained down on the unsuspecting Metkayina camp.

The ambush shattered the peaceful coastline of Pandora in a storm of explosions and searing lasers. But the Metkayina were quick to adapt. The ocean was their home—and they moved through it as naturally as breathing. Using the terrain to their advantage, they began organizing a defense.

Still, wave after wave of human and robotic forces surged onto the beach.

From the rear, a full line of AQ-Series droids emerged from the surf. Their laser cannons rotated and locked onto targets before unleashing systematic volleys of searing plasma—sweeping through enemy lines with ruthless efficiency.

Metkayina Clan – Sacred Grounds

Tribal Member:

"We're surrounded! Call the High Priest!"

The High Priest emerged, clutching a ceremonial staff crafted from sea bones and sacred fibers. Standing amidst the crumbling ruins and roaring flames, his presence radiated determination—a final beacon of hope for his people in the face of foreign invasion.

But faith could not shield him.

Just as he raised his staff and began chanting the sacred invocation, an explosive round pierced through the spiritual barrier. It struck his head. There was no scream. No warning. Only a flash of heat—and then, nothing. His skull evaporated, and his body collapsed into the sacred sands.

---

Scuba Troopers:

"Wipe them out. No exceptions."

The AQ-Series Battle Droids continued their advance—slow, methodical, unstoppable. Like a wall of moving steel, they tore through any who dared resist, their laser cannons firing with ruthless, calculated precision. Every step they took brought death closer—cold, mechanical, and inevitable.

Meanwhile, over the internal comms—

Scuba Trooper 06:

"Colonel Charlie, the Imperial Zoo just placed an order for three Na'vi. They're offering a hefty sum… throne coins."

Scuba Trooper 07:

"Also, Colonel… the Emperor wants a few Na'vi preserved. As trophies. Symbols of conquest."

Scuba Trooper 08:

"And we've got a request from the Ministry of Livestock—one thousand Na'vi. Their skin's the latest fashion trend among Caelestis girls."

Colonel Charlie overheard the tasteless chatter. Veins pulsed on his forehead, his gaze sharp with fury.

Colonel Charlie:

"Shut up. All of you. We're still in an active combat zone!"

His breath came heavy and fast. But orders were orders.

Colonel Charlie:

"Alright. Listen up. Capture two male Na'vi and four females. The rest—eliminate them. Leave nothing behind."

Pandora's Shore – The Rise of Resistance

On the other side of the battlefield, Tonowari, the tribal leader, stood amidst rubble and smoke. His eyes were sharp, focused on the crimson-stained sea that was once their sacred home.

Tonowari:

"We cannot retreat! This is the land of our ancestors. This is our home!"

His voice echoed across the coast. All along the shoreline, the Na'vi stood—scarred, weary, but unbroken. Armed with whatever they could find, they lined up side by side. There was no fear in their eyes, only the fierce resolve to protect what was theirs.

Metkayina Tribe Members (shouting in unison):

"Defend our home! Defend our home!"

But then—

"Pew! Pew! Pew! Pew! Pew!"

Blasts from high-energy weapons tore through the Na'vi ranks without hesitation. One by one, blue bodies fell—lifeless against the sand.

No mercy. No negotiation.

To the Imperium Caelestis, they were nothing more than wild xenos.

And xenos must be exterminated.

Such was the iron law carved into the conquest doctrine of the Celestial Empire.
