The Post-Apocalyptic Courier

Chapter 1: The Last Signature

Deyvorn Karshel adjusted the straps of his worn courier vest, his eyes flicking down to the GPS strapped to his wrist. It flickered—a stuttering blue line against a backdrop of gray, pixelated static—but it held.

"Still got a signal? Seriously?" he muttered to the empty street, his voice raspy from disuse. "How are you doing that, little buddy? The cell towers are literally burning."

He tapped the screen. It chirped back a helpful, cheery tone that felt like a slap in the face.

"Yeah, yeah, I know," he said, checking the address again. "The 'Gold Star Service' guarantee. Deliver the package or lose the quarterly bonus. I’m not losing that bonus. Do you have any idea how much canned peaches go for these days?"

The lobby of the Obsidian Heights high-rise loomed ahead, a cavern of shattered glass and rotting debris. He adjusted his grip on the customized delivery cart—a heavy-duty steel frame he’d reinforced with layers of scrap metal and plywood. It looked more like a portable barricade than a shipping vehicle.

"Alright, Deyvorn. Just a quick drop-off. In and out. No need to make friends with the local residents," he whispered, pushing the cart forward.

The lobby was a mess. A dozen or so figures in tattered business casual attire stood slumped against the concierge desk, their heads lolling at unnatural angles. As he rolled the cart onto the cracked marble floor, the sound of the squeaky wheel echoed like a siren.

"Hey, guys. Look, I’m just passing through. Delivery for 14B," Deyvorn said, his tone casual, almost conversational, as if he were asking for directions to the elevator. "You mind? I've got a deadline. Big corporate payout on the line."

One of the figures, a man in a shredded Brooks Brothers suit, turned. His jaw hung slack, revealing teeth that hadn't seen a toothbrush in months.

"Don't look at me like that," Deyvorn sighed, tightening his grip on the handle of his cart. "I don’t have any brains for you. Just bubble wrap and printer ink. Boring stuff."

The man lurched forward. Deyvorn didn't hesitate. He slammed the side of his cart into the creature’s chest, pinning him against the wall.

"Listen, man, I get it. The commute is a killer," Deyvorn joked, though his knuckles were white where he gripped the steel. "But you’re blocking the lobby. You want me to file a complaint with management? Oh, wait. I think they’re the ones currently eating the janitor."

Another three zombies peeled away from the shadows, their groans sounding like dry leaves skittering on pavement.

"Okay, changing of plans," Deyvorn muttered.

He spotted a fire extinguisher mounted on the wall near the stairwell door. He lunged for it, unhooking it with a sharp yank.

"Sorry, building maintenance! I’ll bring this back later!"

He pulled the pin and blasted a thick, white cloud of chemical powder directly into the faces of the approaching group. They stumbled, coughing—or whatever the undead did instead of coughing—and clawed blindly at the air.

"Right. See ya later, fellas. Try to get some sleep," he chirped, shoving his cart through the stairwell door and slamming it shut behind him.

He leaned against the metal frame, breathing hard. The silence of the stairwell was heavy, smelling of mildew and stagnant air.

"Stairs. Why does it always have to be stairs?" he groaned. "Fourteen floors. The elevator’s dead, obviously. If I die on the way up, I’m writing a very stern letter to HR."

The climb was grueling. Every time he passed a floor, he pressed his ear to the concrete door. Silence, then a scratch. He pushed on. His heart hammered against his ribs, a frantic rhythm that matched the ticking of his watch.

"Almost there, Deyvorn. Think of the bonus. You could buy, like, ten cans of soup. Maybe even a decent bottle of water. Think of the hydration."

He reached the fourteenth floor, his lungs burning. He dragged the cart to 14B, a sleek, modern apartment door that looked suspiciously untouched.

"Delivery!" he shouted, knocking on the heavy wood. "Package for the tenant of 14B! You home?"

Silence.

"Come on, pal. I trekked through the lobby of the damned for this. Don't leave me hanging. I’m supposed to get a signature."

He knocked again, louder this time. He tried the handle. It turned smoothly, the lock long since compromised or simply left open by a desperate occupant who had fled in the night. The door creaked inward.

The apartment was empty. A coffee cup sat on the counter, a thick layer of dust coating its surface. A laptop lay on the floor, its screen smashed.

"Great," Deyvorn muttered, dropping his cart. "Nobody home. Just my luck. A wasted trip. You know, you’re supposed to cancel these things, buddy. I don't work for free."

He walked toward the center of the living room, feeling the weight of the silence. He was stranded. He couldn't go back down the way he came—not without another extinguisher, and he’d used his only one.

"Fantastic. Just fantastic. I’m trapped on the fourteenth floor of a tomb because a customer decided to skip town without updating their delivery preferences."

He kicked a small side table in frustration. The sound was too loud in the quiet room. He sighed, rubbing his face with his hands.

"What am I supposed to do now? Write 'Return to Sender'? There’s no sender left, man. The whole world is 'Return to Sender'."

His gaze drifted to the smart-locker by the entrance—a small, high-tech compartment built into the wall for deliveries. It was pulsing with a faint, steady green light.

"That’s weird," he whispered. "Power’s out in the rest of the building. Why is that thing still lit?"

He stepped toward it, his curiosity overriding his exhaustion. He pressed a button on the console. A hidden compartment clicked open, revealing not a receipt, but a compact, military-grade radio handset.

He picked it up, feeling the cold, heavy weight of it. A static-filled voice cut through the air, sharp and clear.

"...if anyone is receiving this, stay away from the city center. The containment zone has been breached. I repeat, the containment zone is breached. We have survivors at the north extraction point, but you need a clearance code to get through the perimeter."

Deyvorn stared at the radio, his jaw dropping.

"Clearance code?" he asked the device, his voice barely a whisper. "I’m just a delivery guy. What the hell did I just walk into?"

He looked down at the package he was holding—the package he had risked his life to bring to a ghost. It wasn't just printer ink and bubble wrap anymore. It was something else. Something heavy.

"I have a feeling," he said to the empty apartment, "that this isn't about the quarterly bonus anymore."
