Life inside the QZ was a slow, grinding adjustment. For the first few months, Ethan and Grandpa Jason settled into a weary routine. Their assigned quarters were small, cramped, smelling faintly of stale sweat and old concrete, a far cry from the fresh, boundless air of the woods. Yet, it was warm, and the food, though bland and rationed, was consistent. Grandpa Jason, true to his word, quickly found work in "procurement," a euphemism for sanctioned scavenging runs into the desolate ruins outside the walls. His quiet efficiency and uncanny ability to return with more than expected, often in better condition, quickly earned him a grudging respect from the FEDRA officers. Ethan would spend his days in the communal children's area, a noisy, chaotic space that grated on his heightened senses. He mostly observed, drawing caricatures in the dust with a stick, listening to the cacophony of voices, learning the intricate social hierarchies of the desperate.
He didn't make friends. Other kids sensed something different about him – his quiet intensity, the way his eyes seemed to see too much, his unflappable composure even when a fight broke out over a dropped toy. They called him "Ghost" sometimes, a name he didn't mind. It suited him. He watched the soldiers, their patrol routes, their changing shifts, their tired faces. He noted the subtle tension in the QZ, the way people averted their eyes, the hushed whispers about "incidents" outside the walls, and the unsettling silence that sometimes fell over the loudspeakers. He knew, with an instinct refined by years in the wild, that this fragile peace was just an illusion.
Grandpa Jason would return from his runs, his face tired, but his eyes always finding Ethan first. In the quiet of their small room, under the dim, flickering electric bulb, he would share the realities of the outside.
"Saw a new kind of growth today," he'd mutter, cleaning his knife. "Near the old highway. Like a dark moss. Moves fast."
Ethan would listen, processing the information, mentally updating his internal map of the growing danger.
"Did you get close?" Ethan asked once, his voice small.
"Too close for comfort," Grandpa Jason admitted, a rare tremor in his voice. "Almost stepped on it. It's smarter than the others, Ethan. More patient." He didn't elaborate, but Ethan understood. The threat was evolving.
The air in the QZ grew heavy, thick with an unspoken dread. More and more soldiers were deployed outside, and fewer returned. The medical wing filled up, its lights burning late into the night. Whispers turned into terrified rumors: a breach, not outside, but inside the walls. A new strain. Panic, a frantic, primal beast, began to claw at the edges of the QZ's carefully constructed order.
Then, one morning, the dam broke.
It started with a distant, piercing scream, followed by the rapid staccato of automatic gunfire. Then another scream, closer this time, and another, until the QZ erupted into a symphony of terror. Alarms blared, a raw, grating sound that tore through the air. Gunfire became continuous, a terrifying percussion.
"Ethan! Get up! Now!" Grandpa Jason's voice was sharp, urgent, pulling Ethan from a deep sleep.
Ethan was on his feet instantly, his instincts kicking in before conscious thought. The air filled with the familiar, horrifying, sickly-sweet scent of fungal decay, thick and cloying, far stronger than he'd ever smelled it in the wild. It meant only one thing: the infected were here. Inside.
They burst out of their small room into the chaotic corridor. People screamed, tripping over each other, a desperate, frantic scramble. Soldiers, once symbols of order, were now just as terrified, firing wildly, their faces contorted with horror. And then, the infected.
They were everywhere. Runners, fast and relentless, their distorted faces contorted into hungry snarls, their bodies slamming into terrified civilians and soldiers alike. Clickers, their heads grotesque, mushroom-like growths, emitting their terrifying echolocation clicks, each sound a chilling promise of a brutal end. The corridor was a slaughterhouse.
Grandpa Jason moved with a terrifying grace, a blur of motion. He had a battered military rifle, acquired from one of his "procurement" runs, and he used it with deadly precision, taking down infected with swift, clean shots to the head. He was a force of nature, a whirlwind of protective action, his focus solely on Ethan. He moved them through the surging crowds, pushing, pulling, shielding Ethan from the worst of the horror.
"Stay close, Ethan! Don't look back! Keep moving!" His voice was a low roar amidst the screams.
Ethan, despite the overwhelming chaos, remained eerily calm. His mind, honed by years of silent observation and guided by those subconscious memories, was already calculating escape routes, spotting the weakest points in the surging tide of bodies. He saw a broken window, a ventilation shaft, a collapsing wall. His body moved with an effortless fluidity, twisting, ducking, sliding through gaps, a perfect complement to Grandpa Jason's brutal efficiency. He was a small, silent ghost amidst the carnage.
They fought their way through what felt like an eternity, through corridors slick with blood and fungal spores, past the gruesome sight of people turning, their bodies contorting into grotesque new forms. The air was thick, suffocating. They reached a series of maintenance tunnels, a narrow, dark passage that promised a path out, a chance for escape.
Just as they ducked into the dank, cramped tunnel, a Bloater, a hulking mass of fungal flesh, burst through a wall nearby, its guttural roar shaking the very foundations of the building. It was massive, terrifying, covered in thick, plate-like growths. It launched a volley of fungal bombs, greenish-yellow sacs that exploded into noxious clouds of spores.
Grandpa Jason shoved Ethan forward, deeper into the tunnel.
"Go! Run! Don't stop!" he yelled, his voice raw. He turned, facing the monstrosity, his rifle raised.
He fired, but the shots barely registered against the Bloater's thick armor. The creature advanced, relentless, its heavy footsteps shaking the ground. Grandpa Jason continued to fire, trying to buy Ethan time, drawing the Bloater's attention.
Then, from the side, a Runner, its movements a blur, lunged from the shadows, hitting Grandpa Jason before he could react. He stumbled, his rifle clattering to the ground. He lashed out with his knife, burying it deep into the Runner's head, but not before its jaws clamped down hard on his arm, tearing flesh.
A gasp tore from Ethan's throat.
"Grandpa!" he screamed, trying to turn back, to help.
"No! Ethan! Go! That's an order!" Grandpa Jason roared, his voice laced with agony but also an iron will. His eyes, meeting Ethan's, were filled with a profound sorrow, a fierce love, and a desperate plea. He knew. His time was short. He would buy Ethan seconds, minutes, whatever he could. He pushed Ethan with a final, desperate shove, propelling him further into the narrow tunnel.
As Ethan stumbled forward, propelled by his grandpa's last desperate push, something else happened. From the dark, unyielding wall of the tunnel, something lashed out. A distorted, infected limb, unseen in the chaos, its movements hidden by the shadows and the din, connected with Ethan's leg. He felt a searing, sharp pain, a tearing sensation. A bite. A deep, agonizing bite on his calf. He cried out, not in fear, but in pure, white-hot agony. He stumbled, falling hard, but the momentum carried him forward, away from Grandpa Jason, away from the roaring Bloater, away from the screaming.
He scrambled blindly through the dark, twisting tunnel, the pain in his leg a burning fire, Grandpa Jason's final, desperate roar echoing in his ears. He crawled, he stumbled, he pushed himself onward until he burst out into what seemed like a collapsed, abandoned section of the QZ, still within the outer walls but far from the immediate carnage. He found a hiding spot, a dark, rubble-strewn corner beneath a half-collapsed staircase, and collapsed, gasping, clutching his throbbing leg.
The QZ continued to scream around him, but the sounds were muffled, distant. He was alone. Truly alone now. Grandpa Jason was gone. His parents, still a mystery. And the bite.
Days bled into a blur of pain, fear, and a terrifying wait. He expected the fever, the transformation, the horrific unraveling of his body. He knew what happened to those who were bitten. He remembered his grandpa's lessons about the symptoms, about the rapid spread of the fungus. He saw the wound, angry and red, festering slightly. But the fever never came. The hallucinations, the pain, the tell-tale changes – nothing. The wound, slowly, agonizingly, began to heal.
A week later, the scar was still angry, but the skin was knitting. Two weeks, and it was a raised, jagged line, a stark reminder. He was immune. He didn't understand how or why. He was just… different. The revelation settled over him like a cold, heavy shroud. It brought no joy, only a profound, isolating certainty. His grandpa was dead, killed by the very thing that couldn't kill him. His parents were gone, victims or participants in a world that bred such horrors. His immunity was a secret, a burden that separated him from everyone else. It was his curse and, he realized with a chilling clarity, his ultimate purpose. He would understand. He would find out why. He would find out everything.
