Valve Cage

The heat rising from the lower pit hit my face like an open furnace. The filtered air from my respirator felt hot and sticky against my lips, making every breath a struggle. I gripped the iron rungs of the ladder, the metal so hot it felt like it was burning straight through my leather gloves. Below us, the lake of raw pathogen bubbled, spitting pops of crimson mist that floated upward like sparks from a campfire.

"Keep your footing, Valerie," Garrison shouted from below me. He was moving fast, his boots clattering against the iron frame. He didn’t look down at the boiling red liquid. His eyes were fixed on the central distribution node—a massive, cylindrical steel cage suspended by four thick hydraulic chains directly over the center of the pit.

"The air indicators are dropping into the red," I called out, my voice muffled by the rubber mask. "The atmospheric moisture is forty percent pathogen base now. If these seals fail, we won’t last three minutes."

"They won’t fail," he said. He reached the bottom of the ladder, stepping onto a narrow, grated platform that vibrated violently with the pulsing rhythm of the core. He reached up, his large hands catching my waist to assist me down the final three rungs. The moment my boots hit the grate, the sheer heat of the floor made me jump. It felt like standing on a hot stove.

The mechanical voice boomed through the chamber again, louder and more distorted by the heat. Atmospheric release sequence initialized. Ten minutes to primary valve activation. Evacuate all personnel immediately.

"The control panel is inside the center cage," Garrison said, pointing down the narrow metal walkway that stretched out over the bubbling lake toward the suspended cylinder. The walkway was less than two feet wide, with no handrails, slicked with a thin, oily film of condensed red vapor. "The backup manual wheels are locked beneath the primary electronic servos. We have to tear the casing off to reach the hydraulic pins."

"I have the pry bar from the skiff," I said, unbuckling the side strap of my backpack. I pulled out the steel tool, the metal cold against my palms for only a second before the ambient heat of the room warmed it. "But Garrison, if we pop those pins while the system is under pressure, the blowback will vent straight into this chamber."

Garrison took the pry bar from my hands, his fingers brushing against mine. His grip was tight, his eyes locking onto mine with a fierce, dark intensity that ignored the sirens and the heat. "The blowback will vent into the primary core line first. It takes ninety seconds for the pressure to reverse and breach the lower seals. That is your window to get back up the ladder."

"I told you I am not leaving you here to die in a hole," I said, my teeth grinding together behind my mask. "We override it together, or we both drop into that pit. Stop trying to play the sacrificial hero."

A hard, grim smile touched his lips, his thumb pressing briefly against the back of my hand. "I am not a hero, Valerie. I am a tactical officer with a dead squad and a ruined sector. The only thing I have left to protect is right in front of me. Now, move."

We sprinted down the narrow walkway, our boots making sharp, echoing slaps against the iron mesh. Below us, the red lake seemed to rise, the thick bubbles bursting with a low, wet sound that made my skin crawl. The sweet scent of wild berries and burnt sugar was so concentrated now that it tasted heavy on my tongue, bypassing the chemical filters of the mask.

We reached the central cage. The structure was a massive web of iron pipes and high-voltage cables, all feeding into a central silver housing marked Manual Pressure Override. The digital interface on the front of the box was flashing a steady, angry violet light, showing a countdown timer ticking toward single digits.

"Get the left side," Garrison ordered, jamming the flat edge of the pry bar into the seam of the reinforced casing. "When I lift, you throw your weight onto the lower lever to release the hydraulic fluid."

I grabbed the iron handle at the base of the machine, my boots slipping slightly on the oily grate as I tried to find leverage. "Ready when you are!"

Garrison growled, his shoulder muscles bunching under his torn uniform as he threw his entire weight against the bar. The reinforced steel plates of the machine groaned, the rivets popping out one by one with sharp, gunshot-like cracks. A stream of white, superheated steam hissed out of the opening, spraying across his cheek and leaving a raw, red burn line. He didn’t even flinch. He kept pushing, his knuckles white on the iron.

"Now, Valerie! Pull it!"

I slammed my body weight downward onto the lower lever. The old iron handle resisted for a second, frozen by decades of dust and heat, before it snapped downward with a violent, metallic clunk.

Deep within the floorboards beneath our feet, a massive hydraulic pump shrieked. The lake of red fluid below suddenly went still, the bubbles freezing as the immense pressure from the geothermal lines reversed, rushing backward into the main storage tanks.

The digital timer on the console froze at exactly six minutes.

Warning, the automated voice crackled, the tone suddenly changing to a rapid, high-pitched alarm. Core coolant line failure. Manual override detected. Pressure building in primary distribution lines. Thermal core breach imminent in ninety seconds.

"It worked," I gasped, wiping the sweat from my eyes. "The valves are locked."

"The valves are locked, but the pressure has nowhere to go," Garrison said, dropping the pry bar. He turned to me, his hands immediately coming up to grab my shoulders, his eyes wild with an urgency that wasn’t there before. "The core is going to blow, Valerie. The entire mountain is going to cave inward in less than two minutes. Run!"

Before I could turn toward the walkway, a loud, metallic crash echoed from the top of the ladder platform.

The security door at the upper entrance ripped completely off its hinges, flying through the air and smashing into the concrete wall of the upper catwalk. Standing in the threshold, her body silhouetted against the bright lights of the upper levels, was a figure that made my blood turn to ice.

Cynthia.

She hadn’t died in the gorge. Her clothes were completely gone, replaced by a charred, dead-gray skin layer that looked like cracked volcanic rock. Her limbs were longer now, her fingers ending in jagged, bone-like talons that scraped against the iron rail as she moved. Her face was a nightmare of split flesh, but through the black fluid leaking from her eyes, those crimson pupils were still there.

She looked down at us in the center cage, her split jaw opening to emit a sound that shook the very foundations of the room—a loud, rhythmic clicking that sounded like a thousand teeth snapping together at once.

"She tracked the scent of the serum," I whispered, my hand falling uselessly against my side. "She followed us down the drainage lines."

Cynthia launched herself from the upper platform, her mutated body descending thirty feet through the red mist straight toward our narrow walkway.
