It's Space Tomb-Raiding!

After reading the planet's logs from a thousand years ago, Hogg understood what had happened to the unfortunate Coral.

The plague mentioned in the logs was actually the Pariah Nexus activated by the Necrons. To the soulless Necrons, the Pariah Nexus had been a weapon of war during the War in Heaven. It could perfectly suppress the soul-signatures and Warp connections of the Old Ones' creations—like a single use of Severed Rations.

The Pariah Nexus, created using the properties of Blackstone, had enveloped Coral a thousand years ago. The humans there weren't Weirdboyz from the War in Heaven. Their souls soon began to weaken, and they slowly became the walking dead in the truest sense of the word. Before they perished, though, they managed to seal the Necrons away.

It had to be said: the humans of a thousand years ago, who still had some remnants of advanced technology, were truly fierce. Even stranded on a planet without the ability to travel through space, they had managed to seal a Necron tomb by taking their enemies down with them.

After explaining the truth of what had happened here and giving everyone a rundown of the Necrons' basic units, the exploration team continued toward the location marked in the data. The fleet stationed in orbit also sent down a large number of engineers and landing craft to begin excavations.

The assembled teams reached the location recorded in the logs: a vast basin, where several rifts split through the rock. Wrecked vehicles and weapons were scattered everywhere, and the ground was covered in shattered glass, melted by the intense heat of energy weapons. Human bones and Necron wreckage lay buried in the soil, while a massive alloy plate sealed the Necron tomb below the depths of the fissure.

As the saying went, the bigger the waves, the more valuable the fish. There might be a dormant tomb of a Necron Dynasty beneath Coral. As the pinnacle of physical technology in the Warhammer universe, a Necron tomb was a vast treasure trove to humanity.

Ginny, the Fourth Company Captain, had arrived with reinforcements aboard a landing craft. After sharing the exploration team's data, she asked:

"Father, why is this species called the Necrons?"

Seeing that his little girl was here, Hogg patiently explained:

"Just like I told you before about how the Old Ones created the Eldar, the Necrons were once a short-lived species called the Necrontyr. They grew jealous of the Old Ones' long lives and great power, so they went to war. Of course, the Old Ones beat them so badly they didn't know which way was up, and drove them back to their homeworld. That was when things took a turn.

The soldiers nearby listened to their old man's story with eager curiosity, and couldn't help stopping their work. Hogg angrily kicked Ross, who was strutting around in front of him with his mohawk.

"Father, why did you hit me?" Ross asked, bewildered. Had his father stopped loving him?

"Less talk! You can brag all you want, but keep working," Hogg continued.

"Later, the C'tan—the gods of the physical universe—sent the Deceiver to the Necrontyr. It tricked them, claiming that Biotransference would make them stronger.

"But the truth was that Biotransference turned the Necrontyr into skeletal robots made of Living Metal, and the Deceiver swallowed their souls like little snacks.

"The Necrontyr perished. All that remained were the Necrons, an AI race unwilling to accept the truth. Later, the War in Heaven broke out. The Necrons, now greatly advanced thanks to C'tan technology, became the C'tan's servant army and fought a brutal war against the Old Ones' faction.

"Back then, the Warp was still a calm river. That war churned it into chaos, and now the Warp is basically a cesspool."

The encampment was quickly established. After the alloy door had been blasted by Melta for a long time, a gap was cut into it. A vast underground space opened up before Blackwatch.

The floor was strewn with human bones and disintegrated remains. The underground space had originally consisted of only a small passageway, but human weapons at the time had blasted it open into its present form.

A structure glowing with an eerie green light came into view. Some of the Tech-priests let out excited binary shrieks and danced bizarrely on the spot in praise of the Father of Black Light.

Ignoring the embarrassing spectacle, everyone checked their equipment and began to enter. Hogg, tough as nails, took point as the team's shield. His Terminator-armored guard followed, while the Tech-priests and the physically fragile Eldar were protected in the middle as ranged support.

Hogg, a loyal Imperium player in his previous life, didn't know much about Necron military lore. Luckily, his good friend had explained enough for him to tell how large this Necron tomb was. A candle was planted above their heads and lit, and they were told it was an essential part of archaeological work on ancient Terra.

The passageway, built entirely of black metal, was seamless. Damaged Necron soldier remains and Gauss Rifles lay on the floor. These would soon be packed up and taken to the surface for study.

The cluttered floor and damaged structures showed that this Tomb World had been almost completely crippled. The Canoptek Scarabs, which served as basic engineers, were nowhere to be seen, probably because they had been dormant for too long. Hogg was relieved; the Necrons' weapons dealt real damage, and one careless mistake could cost them lives.

As they pushed on, they discovered room after room, some still containing sealed Necron soldiers. Hogg left them undisturbed and simply sealed the rooms back up.

The finished weapons in the armory were in good condition and were packed up and carried away. Then, as they ventured deeper into the core area, something unexpected happened.

As Hogg entered the core area, a squad of Necron soldiers appeared directly in front of him. Their silver-gray Living Metal skeletons and terrifying skulls glowed green, making them look just like Terminator T-800s. The moment they spotted the intruders, the Gauss Blasters in their hands fired green disintegration beams.

Bolters roared. At the same time, shields wreathed in emerald-green energy sprang up in front of the squad. The Ork heads mounted on them began to laugh wildly and unleash a mighty Waaaagh battle cry, perfectly holding back the destructive beams.

The shield-bearing guards charged forward with Hogg and rushed the Necrons. Their smaller frames gave them greater agility and made them harder to hit.

The Bolters fired at point-blank range. Thirty-round magazines tore the enemy Necrons to pieces. Then they switched to melee weapons and charged the ever-growing horde.

Two mechanical tentacles unfurled and lashed at the enemy. The Power Klaws, shimmering with Disruption Fields, could tear apart the Necrons' Living Metal bodies with a single blow. The powerful Gauss disintegration beams were canceled out by dark-red Psionic Energy. Hogg's Primarch-level destructive power was on full display as he cleaved through the Necron ranks like a blade. Piercing alarms blared. More Necron soldiers appeared, but Hogg cut them down one after another.

The team rushed forward, their magnetic boots clanging against the floor. Unable to use psychic screams to disrupt the enemy, the Banshees wielded a star-marked pistol in one hand and a monomolecular bone blade in the other, splitting the battlefield under the Space Marines' protection.

Soon, the Necron soldiers couldn't keep up with Blackwatch's rate of slaughter. Just then, Hogg sensed an abnormal spatial fluctuation. The weapons platform locked onto the presence and opened fire around the corner in anticipation. Plasma sparks struck a target that had just appeared: a Deathmark sniper.

"Idiot! Using a sniper rifle indoors? In such a hurry to visit your own grave on Tomb-Sweeping Day?"

"Men, charge with me! Damn it, they've got Deathmark snipers. This tomb's bound to have good loot. Kill them, and it's ours! Waaaagh!" Hearing that there was good loot, everyone's eyes lit up green, and they charged forward with all their might.

"Waaaagh!!!! Charge!! Kill those damn Xenos!"

I read pretty much all the comments. The author plays tabletop games and usually likes to fight, fight, fight. If you spot anything vague or inaccurate in the lore, feel free to point it out. Hehe.
