My Final Enemy is Me

The last thing Frathan remembered was the screech of tearing metal and the blinding white heat of an exploding kinetic thruster. Then came the void—a hollow, suffocating silence—before his lungs suddenly burned with the sensation of inhaling molten glass.

He collapsed onto a cold, uneven floor, his eyes snapping open. He wasn't in the training hangar anymore. He was in a damp, torch-lit cavern reeking of rot and sulfur.

"What the hell?" Frathan wheezed, clutching his chest.

A low, guttural chittering echoed from the shadows. Three hunched, green-skinned figures stepped into the flickering light, their jagged, rusted blades glistening with dark ichor. D-Rank Goblins.

"Oh, you’ve got to be kidding me," Frathan muttered, scrambling backward. "Is this a joke? Who’s running this simulation?"

"Grak! Kill!" one of the creatures hissed, lunging forward with erratic, twitchy movements.

Frathan ducked, the blade slicing a lock of his hair. His heart hammered against his ribs like a trapped bird. This feels too real. My legs... they don’t feel like my own.

"Listen, fellas, I don’t know if we got off on the wrong foot, but I’m really not in the mood for a brawl," Frathan said, sliding behind a pile of jagged rocks.

"Meat! Soft meat!" the leader shrieked, pointing a crooked finger at Frathan’s throat.

"Yeah, yeah, we’re all meat, we get it," Frathan snapped, grabbing a heavy, loose stone from the ground. "Do you guys have a manager, or is this just a free-for-all murder club?"

The goblins didn't answer; they sprinted, their claws gouging the stone floor. Frathan’s mind raced, his tactical training struggling to override the sheer sensory overload of his new, unfamiliar body. He felt sluggish, his movements lagging a millisecond behind his thoughts.

"Slow. You’re all so damn slow," Frathan grunted, timing his dodge to the leader’s wide, clumsy swing.

He sidestepped, feeling the wind of the blade pass inches from his ear. He didn't think; he reacted. He slammed the stone into the lead goblin’s knee, hearing a sickening crunch.

"Gotcha, you ugly little pest," Frathan hissed.

The goblin crumpled, screeching in agony. "Help! Crush the soft thing!"

"Not today, chief," Frathan said, vaulting over the fallen creature. He snatched the goblin’s discarded blade from the floor, his grip feeling awkward but strangely intuitive.

"You’re adapting fast, human," a mechanical, synthetic voice chimed in his head.

Frathan froze, parrying a desperate strike from another goblin. "Who said that? Where are you?"

"Testing grounds: Sector 01. Difficulty: D-Rank. Survival probability: Negligible," the voice replied, indifferent.

"Negligible? Thanks for the vote of confidence, buddy," Frathan shouted, swinging the blade in a wide, desperate arc that sent the second goblin tumbling backward.

"The timeline you inhabit is a localized simulation," the voice continued. "A precursor to the actual integration. A sandbox for the upcoming harvest."

"Harvest? Integration? What are you talking about?" Frathan yelled, his voice cracking as he slammed his shoulder into the final goblin, knocking it off balance.

"The main event approaches. This is merely the trial run," the system droned.

Frathan didn't have time for existential dread. The leader had recovered, limping forward with blood dripping from its jagged nose. Its eyes burned with a primal, focused malice.

"You think you’re special?" the leader growled, raising its blade. "You die like the rest."

"I died once today already, pal. I’m starting to think it’s not all it’s cracked up to be," Frathan retorted.

He lunged, not at the leader’s chest, but at the shadow where the leader’s limp made it sluggish. He pivoted on his heel, driving the rusted blade into the creature's exposed neck.

The goblin went rigid, its eyes widening as the life drained from them. It slumped to the floor with a wet thud.

Frathan stood over the corpse, gasping for air, his hands shaking violently. The silence of the cavern returned, heavy and suffocating.

"Is it over?" Frathan breathed, wiping sweat from his forehead.

"Assessment complete," the system chirped. "Target eliminated. Rewards processing."

Frathan looked down at the pile of loot where the leader had fallen. Amidst a scattering of worthless copper coins and rusted scrap, something caught his eye. A small, circular token, made of a material that looked like shifting, liquid mercury.

He reached down, his fingers hovering inches away. It pulsed. A low, rhythmic thrumming vibrated through his bones, suggesting a power that defied the laws of physics he’d known his entire life.

"Wait, what is this thing?" Frathan asked, his voice barely a whisper.

"Warning," the system stated, the tone shifting to a sharp, jarring alert. "Unauthorized object detected in staging area. Reality integrity failing."

The cavern walls began to ripple like water. The torches flickered, turning a bruised, unnatural violet.

"Wait—what do you mean failing?" Frathan shouted, reaching for the token. "I’m not done here!"

"Timeline collapse in ten seconds," the voice replied, cold and devoid of empathy. "Good luck in the real world, subject."

Frathan grabbed the token. A shockwave of impossible energy surged up his arm, turning his world into a kaleidoscope of white noise and shattered memories.

"Hey! Are you listening to me?" Frathan screamed into the void, but the cavern was already dissolving into nothingness.

He blinked, and for a fleeting second, he saw the sky. It wasn't the blue he remembered. It was a swirling, crimson expanse, scarred by mass

ive, floating fortresses that defied gravity.

Then, the floor vanished entirely.
