The fluorescent light above register three flickered again.

Ethan Cole watched it with the detached interest of someone who'd been staring at the same ceiling for six months. Flicker. Pause. Flicker-flicker. Pause. If the light had a pattern, he'd have figured it out by now. Six months of night shifts at QuickStop Convenience gave you that kind of time.

11:47 PM. Thirteen minutes to midnight. One customer in the last two hours — a college kid buying energy drinks and ramen, the universal currency of desperation. Ethan had been that kid once. Three semesters of computer science before the money ran out and his mother's medical bills ate everything else.

Now he was here. Twenty-two, no degree, no plan, scanning barcodes at a store that smelled permanently of hot dogs and floor cleaner.

He leaned against the counter, scrolling through his phone. Reddit. Twitter. The usual doomscroll. Climate collapse. Economic crisis. Some billionaire launching another rocket while schools closed.

The fluorescent light flickered one last time — and went out.

Then every light on the block went out.

---

Ethan's first thought was practical: *Power outage. Check the breaker.*

His second thought came when he looked outside — and saw the sky.

It was cracking.

Not metaphorically. The sky itself — the actual dark expanse above the city — had a fissure running through it. A jagged line of white light, like someone had taken a cosmic chisel and split the firmament from horizon to horizon. The crack pulsed, widened, and from within it poured a light that wasn't light. It was information. He could feel it — data streaming through the air like invisible rain, settling on his skin, seeping into his bones.

Every car alarm on the street screamed to life simultaneously.

Every phone in the store — his, the display models, even the ancient calculator by the register — lit up with the same message:

``` SYSTEM INTEGRATION: EARTH-7741 STATUS: INITIALIZING POPULATION SCAN: COMPLETE CLASS ASSIGNMENT: IN PROGRESS ```

Ethan stared at his phone screen. The text wasn't in any app. It was burned directly into the display, overriding everything else.

"What the—"

The screen changed:

``` ETHAN COLE AGE: 22 CLASS: ███ERROR███ LEVEL: 1 HP: 100/100 MP: 50/50

SKILLS: [CORRUPTED] STATUS: ANOMALY DETECTED ```

He blinked. Read it again. Tapped the screen — nothing responded. The message was baked into reality.

Outside, people were screaming.

---

Ethan stepped out of the QuickStop into a world that had stopped making sense.

The crack in the sky had widened into a wound — a gash of white fire stretching from one end of the city to the other. From within it, things were falling. Not debris. Not rain. *Things*. He could see them descending like dark seeds, hitting the ground blocks away with impacts that shook the pavement under his feet.

A woman ran past him, clutching a toddler. "They're everywhere! They're—" She didn't finish. Just ran.

Ethan looked down the street and saw his first monster.

It was the size of a large dog, but it wasn't a dog. Four legs, yes, but the body was wrong — elongated, covered in something between fur and scales, the color of wet asphalt. Its head was too flat, mouth too wide, filled with teeth that caught the light from the sky-crack like tiny mirrors. It was standing on top of a flipped sedan, sniffing the air.

And Ethan could see something no one else could.

Floating above the creature, visible only to him, was a translucent panel:

``` [RIFT HOUND — Lvl 3] HP: 45/45 WEAKNESS: Underbelly (Critical Zone) Slow turning radius (>2s) SYSTEM NOTE: Pack hunter. Alone = vulnerable. Exploit: turn delay after lunge ```

The information hung in the air like subtitles in a foreign film. Clear. Precise. Useful.

The Rift Hound's head snapped toward him. Yellow eyes locked on. It growled — a sound like grinding metal.

*Okay. Okay okay okay.*

Ethan's hands were shaking. He was not a fighter. He was a convenience store clerk who couldn't even keep up with a computer science degree. But the panel was telling him exactly what to do.

*Slow turning radius. Exploit the turn delay after lunge.*

The creature lunged.

Ethan dove sideways — not gracefully, not heroically. He tripped over the curb, hit the pavement with his shoulder, and rolled. The Rift Hound sailed past him, claws scraping asphalt where he'd been standing. It landed, skidded, and began to turn.

Slow. Just like the panel said.

Two seconds. That was the window.

Ethan grabbed the closest thing — a fire extinguisher mounted on the QuickStop's exterior wall. He ripped it free, swung it with both hands, and slammed it into the creature's exposed underbelly as it was still turning.

The impact jarred through his arms like hitting a car with a baseball bat. The Rift Hound shrieked — a sound that would live in his nightmares — and crumpled sideways. He hit it again. And again. And again, until the shrieking stopped and the creature dissolved into particles of dark light that faded into nothing.

A new panel appeared:

``` [RIFT HOUND DEFEATED] XP: +15 LEVEL UP! → Level 2 NEW SKILL DETECTED: [EXPLOIT WINDOW] → Identify system lag in entity actions → 0.3s freeze on target (increases with level) STATUS: SKILL CORRUPTED — FUNCTIONALITY UNKNOWN ```

Ethan stood there, breathing hard, fire extinguisher dripping with something dark. His hands wouldn't stop shaking.

The sky screamed above him. More dark seeds fell. More car alarms wailed.

And his ERROR interface flickered with a new message at the bottom of the screen, small, almost hidden:

``` ⚠ SYSTEM INTEGRITY ALERT: LVL 1 ANOMALY ACTIVITY LOGGED CORRECTION PROBABILITY: 0.3% ```

He didn't know what that meant yet. He would.

---

The next three hours were the longest of Ethan's life.

The city descended into chaos with a speed that felt almost rehearsed. Monsters — the System called them Rift Beasts — poured through tears in reality. Power was gone. Cell towers were down. Emergency services were overwhelmed within the first thirty minutes.

Ethan moved through the streets in a daze, guided by the impossible panels only he could see. Every Rift Beast had one — floating stats, weaknesses highlighted in red, behavioral patterns annotated like code comments. He wasn't strong. He wasn't fast. But he could read the cheat sheet.

He killed three more Rift Hounds using makeshift weapons — a crowbar from a hardware store, a kitchen knife from a restaurant. Each kill granted XP. Each level-up boosted his stats marginally and increased the Exploit Window duration by fractions of a second.

By 4 AM, he was Level 4. His body ached. His shoulder was bruised from the earlier fall. He had a cut on his forearm where a Rift Hound's claw had grazed him.

But he was alive. And he was starting to understand what ERROR meant.

Everyone else who'd received a Class had a clean interface — he'd caught glimpses over survivors' shoulders. Clean panels, organized skills, clear progression paths. Warrior. Mage. Scout. Healer. Normal Classes for a system that treated the apocalypse like a game.

His interface was broken. Glitched. Half the text was corrupted, skills were listed as `[UNKNOWN]`, and his stat page had fields that didn't exist for anyone else — things like `SYSTEM_ACCESS_LVL: 0.4` and `INTEGRITY_OVERRIDE: PARTIAL`.

But in exchange for the mess, he got something no one else had: he could see behind the curtain. The System was a program, and his Class was a debugger. A glitchy, half-broken debugger — but a debugger nonetheless.

The sky was still cracked open when he found the pharmacy.

---

The Wellness Plus Pharmacy on Fifth Street was barricaded from the inside. Overturned shelves against the glass doors, duct tape holding the cracks together. Through the gaps, Ethan could see movement — people. Survivors.

And he could hear screaming.

Not from the people. From below. The pharmacy had a basement storage area, and something was down there.

He pushed against the barricade. "Hey! Anyone in there?"

A woman's face appeared at the gap — mid-twenties, dark hair pulled back in a messy ponytail, blood on her scrub top. Hospital scrubs. A medical worker.

"Stay back!" she shouted. "There are things in the basement — rats, but not rats. They're huge. We can't—"

A crash from below cut her off. The floor shook.

Ethan looked at the basement entrance — or where it used to be. The door had been ripped apart. And climbing through the wreckage was a rat the size of a golden retriever, fur matted with something dark, teeth bared.

His panel appeared instantly:

``` [BLIGHT RAT — Lvl 2] HP: 30/30 WEAKNESS: Eyes (blind for 3s if hit) Sensitive to UV light PACK SIZE: 6-8 SYSTEM NOTE: Low individual threat, dangerous in groups ```

Behind the first rat, more eyes glinted in the darkness.

"How many people are in here?" Ethan asked, already scanning the store for anything useful.

"Seven. Three kids." The woman's voice was steady despite the terror. *Professional calm*, Ethan recognized. She was used to crisis. "I'm a healer. I got the Healer Class." She said it like she was still testing the words. "I can fix wounds but I can't fight those things."

"I can," Ethan said, pulling the crowbar from his belt. He didn't feel confident. He felt like throwing up. But the panels were clear, and clear information was the only advantage he had.

He stepped through the barricade.

"What's your name?" he asked, not looking back.

"Maya. Maya Chen."

"Ethan. Stay behind me. When I say 'light,' point every flashlight you have at their eyes."

He raised the crowbar.

The first Blight Rat charged.

And the ERROR interface lit up with data — weaknesses, timings, exploit windows — like a battle HUD designed by someone who'd never finished the code.

*Good enough*, Ethan thought.

He swung.
