When The Sun Died

Chapter 16

Serena’s POV

The road bent north, thinning into cracked concrete bordered by dead fields and rusted signposts. We’d been walking for hours, too tired to talk, too tense to relax.

The nests were behind us, but the weight of them walked right beside us.

Asher limped a little. Elara watched every shadow. Kane kept glancing over his shoulder like he expected something to follow.

Nia held onto Elara’s sleeve, quiet as ever.

I kept my rifle ready.

The eclipse-light didn’t fade. It never did. But the deeper we went, the darker it felt as if the sky itself was warning us to turn around.

We didn’t.

We couldn’t.

About an hour later, Kane slowed.

“Wait, look there,” he said, pointing through the broken fence line.

Behind a cluster of collapsed trees and vines, a shape stuck out large, rectangular, metallic. Not a vehicle… a structure.

A building.

Concrete walls. Reinforced windows. A faded blue sign tilted sideways.

Elara squinted. “What is that?”

We stepped closer until the letters came into view through the grime:

‘WESTRIDGE BIOTECH FIELD RESEARCH DIVISION’

My throat tightened.

A lab.

Or what used to be one.

Kane’s eyes widened. “This wasn’t on the map. Serena this could be huge. If they studied anything related to mutation, disease, genetics”

“Slow down.” I raised a hand. “We’re not walking into anything blind.”

The front gate hung crooked on its hinges. No bodies. No blood. Just silence too much of it.

Asher dragged a hand across his forehead. “Do we have to go inside? We’re burning daylight.”

“There is no daylight,” Kane murmured.

“Shut up, Kane,” Asher muttered.

I scanned the perimeter. “If there’s a building still standing, it might have supplies. Medkits. Maps. Data. Anything that helps us understand what we saw back there.”

Asher hesitated… then nodded once. “Five minutes. In and out.”

We approached slowly, stepping around shattered glass and fallen branches.

The front doors were cracked open like someone left in a hurry.

I pushed lightly with the barrel of my rifle.

The hinges groaned as the door slid open.

Inside was a lobby dusty, trashed, but intact. Papers scattered across the floor. A toppled desk, A vending machine cracked open.

But no nests.

No blood.

No bodies.

Elara exhaled shakily. “It’s… empty.”

“Good.” I motioned forward. “Stay tight. We sweep the first floor only.”

Kane was already scanning everything with frantic interest. “Serena, look at these posters. They were studying rapid mutation forms. Cellular instability. Something about environmental triggers. Maybe the eclipse ”

“We don’t know that,” I cut him off.

“But it’s possible.”

Asher ignored the posters. He moved toward a hallway, peeking through each doorway. Offices. Storage rooms. Empty, empty, empty.

Kane was already rifling through a toppled metal cabinet, muttering under his breath. “Lab equipment… centrifuge… microscopes… damn, we might actually be able to run a proper test here.” His hands trembled slightly, eyes darting to Asher.

I didn’t like the look in his eyes. The way he studied Asher wasn’t just curiosity, it was obsession.

“Asher,” Kane said softly, almost reverently, “I need a sample. Just a drop of blood. I want to see… why you didn’t fully… change.”

Asher stiffened. “I said I’m fine. Don’t”

“Just a few drops,” Kane interrupted, ignoring him. “I’ll run it, and we might finally know what the hell is happening inside you.”

I stepped closer, rifle still raised. “If you do this, do it quickly. We don’t know what else is out there.”

Asher sighed, holding out his arm reluctantly. Kane produced a small lancet from a pocket, pricking the inside of Asher’s forearm. A thin line of blood welled up, shining unnaturally dark under the red eclipse light.

Kane carefully collected it, eyes wide with anticipation. “Yes… perfect.”

He set up a makeshift station on one of the overturned desks, centrifuge, microscope, a few vials that still had labels, old reagents.

I stayed by the door, scanning the shadows, while Elara and Nia huddled quietly.

Minutes passed, tense and silent except for the whirring of the centrifuge. Kane’s hands moved with precision, placing slides under the microscope.

“Oh… wow,” he breathed. “Serena… look at this.”

I leaned over the shoulder, forcing myself to see. The slide was alive with movement, cells, almost writhing like tiny organisms. Most of Asher’s cells were normal human blood cells. But mixed in… others. Jagged, dark, irregular cells that pulsed like they had a mind of their own.

“These aren’t just infected,” Kane whispered. “They’re… fighting each other. Look, see the boundaries? The human cells… they’re actively attacking the mutated ones. Your DNA… it’s resisting the Eclipse mutation.”

Asher’s face was drained of color. “So… I’m… stuck between?”

“Half-human, half… something else,” Kane said, mesmerized. “It’s unstable, but it’s adaptive. Your body didn’t just survive the bite, it’s negotiating with it. Every heartbeat is a battle between two different cellular programs. This… this is unprecedented.”

I swallowed hard. The red light from the eclipse above glinted off the broken glass around us, casting the lab in an eerie, pulsing glow.

Kane scribbled frantically in his notebook. “If we can understand this… we might have a weapon. Or a cure. Or… I don’t know yet. But the potential”

“Focus on keeping him alive first,” I snapped, jerking his attention back to the room.

“We’re not turning this into some lab project while the world outside is crawling with monsters.”

He looked up, eyes fierce, but nodded. “Right. Right. But Serena… this is huge. You don’t understand.”

I didn’t argue. I just watched Asher, who looked pale, but the way his veins pulsed there was power there now. Something the Eclipseborn didn’t have. Something that might save us, or doom us if it lost control.

Then Kane frowned. “Wait… there’s more.”

He adjusted the microscope, zooming in. I squinted. The mutated cells weren’t just irregular they seemed to… mutate against themselves. Tiny spikes retracted, clusters dissolved, as if the human cells were rewriting the mutated ones in real time.

“It’s… evolving,” Kane whispered. “Your blood isn’t just resisting it’s… rewriting it. It’s literally unmaking the mutation as it spreads.”

Asher swallowed hard. “So… if I fight… I could… kill the monster part of me?”

Kane didn’t answer immediately. “Possibly. But it’s unstable. If the balance tips the other way…” His voice trailed off.

I stepped closer, resting a hand lightly on Asher’s shoulder. “Whatever happens, we’ll figure it out.

Asher swallowed hard, staring at his arm as if seeing it for the first time. “So… every time I feel strong, it’s my human side winning?”

“Exactly,” Kane said. “But it’s delicate. I want to understand what triggers one side to dominate the other. That’s why we need to run more tests. Controlled conditions.”

I lowered my rifle slightly, finally letting my guard down enough to approach him. “Then we stay. Lock every door, barricade the windows. No one goes out. And no one in, if we can help it.”

Kane nodded, his hands already moving to set up another slide. “Yes. I can work here. We’ll run all the tests we can. Maybe even figure out how to replicate this. Or stop the mutation in others.”

I glanced toward the shattered windows, the red eclipse sky casting the lab in bloodlight. Outside, the nests waited. Intelligent, organized, hunting.

Inside, for the first time that day, we had a semblance of control. A safe place. And perhaps… a way to fight back.
