With the surface buzzing with frantic preparation, the threat from below festered like a splinter in my mind.
The creature my Temporal Echo had warned me about—the one in the deep cavern—was still down there. I could feel it through the soles of my boots, a low-frequency throb that made the roots of my teeth ache. It wasn't just a monster; it was an infection in the earth.
I took a team down before dawn: Alex, Ben, and Sarah. We moved through the reinforced mine shafts in silence, the beam of our flashlights cutting through the stale, heavy air. The further we descended, the hotter it got. The natural cool of the earth gave way to a humid, feverish heat that coated our skin in slick sweat.
"Geothermal vent?" Ben whispered, his voice echoing strangely.
"No," I said, gripping the rough stone wall. "Biology."
We reached the breach point—a section of the tunnel where the mining drills had punched into a natural cavern decades ago. But the cavern had changed.
It was a womb.
A massive, fleshy membrane covered the walls, pulsing with a sickly bioluminescence. It was translucent, and inside, we could see shapes. Human shapes. Or what used to be human. They were suspended in the sac, twitching, their limbs elongating, their jaws distending.
"Mist incubator," Alex breathed, horror plain in his voice. "They aren't just turning... they're being grown."
In the center of the chamber, a fungal bloom the size of a car throbbed, pumping green spore-clouds into the air. It was the heart of the nest.
"We need to burn it," Sarah hissed, raising her flamethrower—a jury-rigged propane contraption.
"Wait!" I grabbed her arm. "The spores. If you ignite them, we'll incinerate ourselves. The whole tunnel will collapse."
I looked at the growth, reaching out with my Plant Affinity. It wasn't a plant—not really. It was something alien, a chimera of fungus and meat. But it was organic. And it drank from the roots of the valley above.
I closed my eyes and focused, not on the nest, but on the ironwood trees high above us. I pushed my intent through the soil, commanding the roots to dig. I urged them to secrete their natural pesticides—the concentrated arsenic and heavy metals they filtered from the earth.
The roots responded.
With a sound like tearing canvas, thick white roots burst through the ceiling of the cavern, writhing like snakes. They punched into the fungal bloom, injecting their toxin.
The nest screamed.
It wasn't a sound in the air; it was a psychic shriek that dropped us to our knees. The fleshy walls turned black instantly, rotting before our eyes. The suspended zombies liquefied, draining into the floor.
"Run!" I gasped, blood pouring from my nose. "It's dying! The spores are releasing!"
We scrambled back up the tunnel as the cavern behind us collapsed in a wet, rotten slough. We sealed the entrance with concrete, leaving the horror buried.
But as I wiped the blood from my face, I knew we had only bought time. The earth itself was mutating.
