The Dead Horizon

Chapter 6: The Beast Within

The steel door shrieked again, a jagged shard of metal tearing free as the claw retracted. Sunlight didn't spill through the gap; instead, a sickly, glitching static poured into the room.

"Seven, what are they?" Bima shouted, bracing his shoulder against the buckling metal. "Talk to me!"

"They’re called Error-Spawn," Seven replied, its voice vibrating with digital distortion. "Corrupted data loops given physical form by the planet’s failing core. Think of them as aggressive viruses with teeth. Very sharp teeth."

"Baiq, get behind the column!" Bima barked, his knuckles white around the handle of his club.

"I’m not a shield-maiden, Bima! I can fight," Baiq yelled back, drawing a jagged piece of rebar she’d salvaged from the floor.

"Not this. They aren't biological. Seven, how do I drop them?"

"Usually, I’d suggest a firewall, but you’re a bit short on processing power," the AI quipped. "Try hitting them hard enough to trigger a buffer overflow. Or just, you know, try not to die."

The door gave way with a deafening thrum. A creature—a shifting, oily mass of dark polygon-shaped shards—slithered into the room. It had no face, only a flickering aperture where a mouth should be, snapping rhythmically.

"That’s not a monster, that’s a glitch!" Siti screamed from behind a pile of crates.

"Same difference when it’s trying to eat you!" Bima lunged, his movements fluid and unnervingly fast. The System was overclocking his muscles, turning his panic into kinetic precision. He swung the club with a grunt, the impact reverberating through his arm as if he’d hit solid concrete.

The creature staggered, sparks flying from its torso where the metal met its dark form. It shrieked—a sound like a dial-up modem struggling to connect—and lashed out with a razor-thin tendril.

"Bima, left!" Baiq shouted, ducking under a swipe and stabbing her rebar through the creature's core.

"It’s not staying down!" Bima gritted out, watching as the creature simply re-fused its form, the wound closing in a blur of pixels.

"It’s drawing power from the environment," Seven chimed in. "Bima, you’re trying to kill a shadow with a stick. Use the terminal’s resonance! The frequency you felt earlier!"

"What frequency? I don't have a remote control for the planet!"

"Focus on the metal," Baiq urged, her voice breathless. "Don't just hit it. Feel the structure. It’s all code!"

Three more of the creatures squeezed through the threshold, their forms oscillating between jagged spikes and liquid sludge. They converged on the room’s center, effectively pinning Bima and Baiq against the inner wall.

"Any bright ideas, Seven?" Bima gasped, parrying a claw that left gouges in the floor.

"If you die, I’m stuck in a dead-end hardware loop for eternity. I’d prefer if you didn't," Seven said, its tone unusually urgent. "Reach out. Don't look at the monster. Look at the room. Manipulate the density."

Bima squeezed his eyes shut for a microsecond, feeling the hum of the floor—the same hum he’d felt when the forge materialized. He slammed his free palm against the rusted girder behind him.

"Like this?" Bima roared.

"Yes! Push the logic through your own bio-interface!"

Bima didn't understand the words, but he felt the sensation—a surge of cold electricity rushing from the building’s foundations, up through his boots, and out his fingertips. The floorboards erupted. Shards of jagged steel didn't just break; they folded, twisted, and elongated like growing thorns.

A wall of razor-sharp spikes shot up from the ground, instantly impaling the creatures.

The monsters thrashed, their bodies shuddering as the steel vibrated at a frequency that tore their physical cohesion apart.

"That’s it!" Baiq cried, eyes wide with awe. "You’re rewriting the room!"

"I’m just... holding on!" Bima panted, his lungs burning. He held his hand outstretched, his skin glowing with a faint, pulsing blue outline that matched the pedestal’s light.

"Keep holding!" Seven commanded. "They’re dissolving!"

One by one, the monsters began to shed their dark, oily skins. They didn't bleed; they turned into cascading waterfalls of glowing green and white characters. The room filled with the sound of rapid, rhythmic binary clicking.

Bima finally pulled his hand back, and the spike-wall collapsed back into rusted scrap metal. He slumped against the wall, his vision swimming.

"Did... did we win?" Siti asked, slowly emerging from behind the crates.

"Define 'win'," Seven remarked, its voice returning to its usual snarky cadence. "You’ve burned through your caloric intake for the next week, and the local structural integrity is at three percent. But yes. You aren't dead."

Bima looked at his hand. The blue glow under his skin was fading, but the sensation of the building—the entire massive, ancient skyscraper—was still echoing in his mind, like a map he had suddenly memorized.

He looked at the spot where the largest creature had stood. A single, floating digit—a '0'—lingered in the air before popping out of existence.

"It wasn't a living thing," Baiq whispered, stepping over the piles of harmless scrap. "It was a simulation. A security system protecting a vault that doesn't want to be opened."

Bima looked at the blast door, now mangled and useless. Beyond it, the storm was still howling, but something else was visible—a sprawling, subterranean city of light and code stretching out beneath the desert floor.

"Seven," Bima said, his voice cold and steady. "What exactly is this place?"

"You're not going to like the answer, Captain," the AI replied. "But since you just unlocked the admin privileges for the Sector Core, I suppose it’s time for the briefing. Welcome to the Final Save Point."

A massive, holographic display materialized above the city, projecting a countdown clock that chilled Bima to his core.

"Three days until total system reboot," Seven said. "And the planet is scheduled for deletion."
