Dust choked his throat, thick and tasting of pulverized concrete. Coughing racked his chest, a violent spasm that sent white-hot spikes through his ribs. Heavy timber pinned his legs, pressing him down into the cold floor. Pressure built behind his eyes, a throbbing warning of a concussion. His hands fumbled in the dark, fingers scraping against jagged metal and rough stone. Every breath felt like inhaling glass, tight and shallow in the suffocating blackness. Darkness pressed against his eyelids, heavy and suffocating. Memories flashed behind his closed eyes, bright and unwanted. Six years had passed, but the sound of tearing metal and his sister's terrified scream still echoed in his skull. Images of that rainy night flashed through his mind, vivid and agonizing. That bridge had collapsed just like this ceiling, a sudden roar of destruction that took everything he loved. He had reached for her, his fingers brushing hers, only to watch her slip into the dark water below. Gritting his teeth, he forced the memory down, locking it away in the dark corners of his mind. Metal scraped against stone as he dragged his left arm upward, searching for leverage. Sharp edges sliced into his palm, but he barely registered the sting over the throb in his legs. Slowly, his fingers wrapped around a thick, rusted piece of rebar protruding from a fallen pillar. Inch by inch, he pulled his body forward, ignoring the screaming protest of his bruised thigh. Blood, warm and sticky, began to seep through the denim of his jeans, wetting the cold dust. With a guttural roar, he heaved his body upward, channeling every ounce of his strength. Finally, the heavy timber shifted, rolling off his legs with a hollow thud that vibrated through the floor. Dragging his useless lower limbs, he crawled out of the tight crevice until he cleared the overhang. Cold air hit him first, shocking his system and making him shudder violently. Smoke, thick and smelling of burning plastic and copper, replaced the stale dust in his lungs. Bleary eyes blinked open, squinting against a harsh, unnatural orange glare that stained the horizon. Ruin surrounded him, a chaotic graveyard of splintered wood, shattered glass, and cracked concrete. Shards of his front door lay scattered yards away, the heavy locks he had meticulously installed completely useless now. Years of preparation, of isolating himself in this reinforced sanctuary, had ended in a single night. Now, there was nothing left but the skeleton of his home and the rising heat of a world on fire. Climbing to his feet, he leaned heavily against a half-broken brick wall, his knees trembling. Far below his hillside retreat, the city was a sprawling furnace of destruction. Black plumes of smoke billowed into the sky, blotting out the stars and turning the clouds a bruised purple. Searing heat licked at his face even from this distance, carrying the distinct, sickening odor of rotting meat. Screams rose from the valley, high-pitched and desperate, echoing off the concrete canyons before cutting off abruptly. Down there, in the grid of burning streets, things were moving. Monsters, mutated and grotesque, ran in packs through the shadows of abandoned vehicles. Their limbs were too long, their bodies twisted into jagged angles that defied human anatomy. Nausea rose in his throat as he watched a massive, pale shape tear the door off a sedan. Why had he survived when they all died, both then and now? This familiar powerlessness clawed at his chest, a heavy, suffocating weight that made it hard to breathe. He had built his walls to keep the world out, to ensure he would never have to watch someone die again. Rage, hot and bitter, washed over him, drowning out the lingering pain in his legs. Tears of frustration mixed with the soot on his cheeks as he slammed his fist into the broken masonry. Suddenly, the chaotic noise of the burning city began to recede, replaced by an eerie, pressurized silence. Sound seemed to warp, the crackle of distant flames dulling into a low, metallic hum. Particles of light, pale blue and electrical, began to gather in the air directly in front of his face. A shimmering, translucent panel materializes before him, bearing the single, chilling word: 'SYSTEM'.
