I slept poorly that night.
The ship's iron hull blocked out all outside light. In the pitch darkness, I felt freezing cold, as if I'd been submerged in polar seawater.
The space was quiet save for the gentle sound of breathing.
At this point we'd abandoned all notions of propriety — men and women huddled together for warmth.
But I couldn't sleep. I lay in the dark, completely awake.
"Is anyone else not sleeping?" I whispered.
"I can't," Marcus said from beside me. "Too cold. I keep thinking about what we're going to find tomorrow."
I pulled my sleeping bag tighter around me. "What do you think we'll find? The expedition team, or..."
"Or something else?" Marcus finished for me.
Neither of us spoke for a long while.
"I hope it's the expedition team," I muttered.
"Yeah," Marcus agreed.
We lay there in silence until exhaustion finally pulled me under.
---
The next morning, we left the ship and set out again under Professor Marshall's lead.
My legs were sore from yesterday's trek, but fear of freezing to death was a powerful motivator.
Professor Marshall said he remembered the coordinates of the research station and could navigate us back.
I didn't ask how he could possibly remember coordinates he'd only glanced at once. At this point, he was our only hope.
We walked for what felt like hours. The landscape was an endless expanse of white, and without landmarks, every direction looked identical.
Eventually, we came upon an area where the ice was thinner, with cracks running through it. Professor Marshall slowed down and studied the ground carefully.
"There's a passage here," he said, pointing at a gap in the ice. "It leads underground."
I stared at him in disbelief. "You want us to go underground? What about the research station?"
"The station could be in any direction. We could wander for days and never find it," Professor Marshall said, his voice flat and unyielding. "This passage might lead somewhere with supplies. Or a way to signal for help."
No one argued. We were too cold and too tired.
One by one, we lowered ourselves into the ice.
---
Inside, the ice cave was otherworldly.
Gemstone-blue light filtered through the ice from every direction. The walls curved and rose like the inside of a frozen cathedral, with towering buttresses of crystalline ice reaching overhead.
Walking through it was like stepping into a fantasy landscape. The ice formations were impossibly beautiful — smooth, translucent surfaces mixed with jagged peaks, all glowing with that ethereal blue light.
We descended deeper into the ice, the cold intensifying with every step.
The passage opened into a larger chamber, and my breath caught in my throat at the sheer scale of it.
Great ridges of ice lay folded across the landscape like the spine of a sleeping dragon, extending endlessly into the blue-tinged darkness.
A profound sense of smallness washed over me. Confronted with this raw power of nature, even we who called ourselves the masters of the earth could feel how insignificant we truly were — mere specks of dust in the vastness of the universe.
In the corner of my eye, something white seemed to flash across the distant ice wall, moving on all fours like a spider.
I blinked, and it was gone.
"Did you see that?" I grabbed Marcus's sleeve.
"See what?" Marcus was watching his footing on the ice.
"I thought I saw something white moving over there."
Marcus frowned. "Probably just the light playing tricks."
But I'd seen it clearly. Something had moved, and fast.
I fell to the back of the group, scanning our surroundings more carefully.
We passed through several ice chambers, all carved from the natural caves beneath the glacier. Some were small and cramped, others cathedral-sized, their ceilings lost in darkness overhead.
Professor Marshall moved through the caves with confidence, navigating the twists and turns without hesitation.
At a fork in the passage, he stopped and looked between the two tunnels. One was narrow and dark, the other wider with a faint blue glow.
He muttered something under his breath — it sounded like "That shouldn't be."
He'd been here before. I was certain of it.
He chose the left tunnel, the dark one.
I would have chosen the right, the wider one with the light. It looked safer. The left tunnel gave me a bad feeling — shadows pooled at its entrance like standing water.
But Professor Marshall was already walking, and we had no choice but to follow.
Kevin brought up the rear, as usual, quiet and steady.
---
The ice cave descended in a series of chambers and passages, each more elaborate than the last.
We came upon areas that clearly showed signs of human activity — chisel marks on the ice walls, flat areas where the floor had been leveled.
"Aren't these... man-made?" Serena whispered, her voice trembling.
Professor Marshall didn't answer. He just kept moving forward, his eyes fixed ahead.
My unease grew with every step. Professor Marshall's behavior had been strange from the start — his silence, his obsession with the ice lake samples, his refusal to explain what we were looking for.
And the way he navigated these tunnels — it was as if he knew exactly where he was going.
The passage widened into what looked like a laboratory of some kind — shelves carved into the ice, a metal table, some kind of equipment gathering dust and frost.
Everything was coated in a thick layer of ice crystals.
But the room was empty.
No people, no signs of recent occupation. Just empty shelves and frozen surfaces.
I was examining the equipment when I heard Serena cry out softly.
"A photo..."
She'd found something tucked between two shelves — a photograph, yellowed with age and covered in frost.
Professor Marshall snatched it from her hands so quickly that we all flinched.
He stared at the photo, his face unreadable, then tucked it into his pocket without a word.
"What was it?" I asked.
"Nothing," he said shortly, and walked on.
But I'd seen the photo. It was a group picture, black and white, of several young people standing together on an ice field.
In the front row, a girl with a large birthmark on her face was smiling broadly.
And standing next to her — looking exactly like Kevin.
---
We continued deeper into the ice.
The chamber narrowed into a tight corridor, and I was so focused on maintaining my footing on the slick ice that I didn't notice the drop until Marcus stepped on a patch of thin ice.
His foot went through, and the entire section collapsed beneath us.
He grabbed my arm as he fell, and I went down with him.
We tumbled through darkness, sliding down a steep ice chute for what felt like an eternity before landing hard on a frozen surface.
"Ow, shit!" Marcus groaned, clutching his stomach.
I scrambled over to him in a panic. "Are you okay?"
He rolled onto his side, wincing. "I think my pride's more injured than anything else. Nothing broken."
I let out a breath and looked around.
We were in another ice chamber — larger than the ones above, with walls that seemed to stretch up forever into darkness.
I could see ice formations in the walls — strange shapes frozen solid. Some looked like geological formations, others like... other things.
"This... there's a door here!!!" Marcus had propped himself up and was shining his flashlight at a section of ice wall.
Embedded in the ice was a perfectly rectangular metal door, with a lock and handle.
"How do we open it?" Marcus pushed at the door. It didn't budge. "We don't have a key! What good is a door without a key?"
He was getting frustrated. "Maybe if we open it, we'll find a way out."
I opened my palm. Inside lay a key I'd found earlier. "Is this what you're looking for?"
---
The door's lock was frozen shut. We had to work the key gently, breathing on the mechanism to melt the ice, terrified the key would snap.
Finally, with a satisfying click, the lock turned.
Marcus yanked the door open, and we stepped through into what was clearly a man-made room.
Shelves lined the walls. Most were empty, but one held a silver metallic box.
Marcus was practically vibrating with excitement. "Is this Nazi treasure? The Nazis came to Antarctica and built a secret base! This could be their treasure vault!"
He was getting more animated. "Maybe they did human experiments here! Created monsters to guard their loot! Think about it — they needed to protect something valuable, so they performed human experiments, and those monsters became their guards!"
His eyes were shining. "Am I making sense?"
I looked at him with perfect sincerity. "You're wasted in science. You should be writing fiction."
Marcus pouted. "Just wait till we get out. I'm writing a bestseller."
The box was silver-colored metal, perfectly square, with no visible seams — almost like a solid block.
"How do we open it?" Marcus poked at it. "No keyhole. Combination lock?"
I turned it over. "No place to enter a code either."
It was surprisingly light — whatever was inside didn't weigh much.
I shook it gently and heard a faint sloshing sound.
...Was I imagining things? How could there be liquid inside? Even magma would freeze solid in this cold!
Marcus stood up, lifting the box. "Let's just smash it open!"
I rolled my eyes. "You think this is styrofoam? Smash it? This is clearly something important. How could you—"
Before I could finish, Marcus hurled the box at the ground.
It hit the ice with a crack, and the lid popped open.
I touched my face. It stung a little.
Marcus crouched over the box, his face illuminated by the flashlight. "What is it?"
Inside the black metal frame, three transparent test tubes filled with green liquid sat in recessed slots.
He picked up a tube and held it to the light. The deep green liquid flowed like jade, giving off an eerie glow.
"What is this stuff? Liquid? How is that possible?" He frowned. "It's not poison, is it?"
"Green and gross-looking. Kind of scary."
Marcus looked disappointed and sighed. "All that security, and it's just green goop. No gold bars. So much for getting rich."
He tossed the tube to me. "What's this good for? Drink it and become Superman?"
I thought about it, then slipped the tubes into my backpack. "Maybe it turns you into a Ninja Turtle."
This was clearly some kind of important experimental material.
In every movie, the stuff in sealed vials like this was either the ultimate poison that could destroy humanity or the ultimate cure that could save it.
Either way, we needed to take it with us. It might come in handy.
---
We couldn't stay here forever. The cold would slowly kill us if we didn't find a way out.
Going back the way we came was out of the question — there could be a monster waiting at the top for us.
We had to find another route.
But this chamber was sealed tight. No visible exits, no other doors.
I tapped on the ice walls, listening for hollow sounds.
"There might be another passage in this cave. Let's check."
We knocked our way around the room until I found a section that rang hollow instead of solid.
My heart leapt. A way out!
"Here. Hit this spot. Our lives depend on it." I tapped up and down, estimating the size — big enough for a person.
Marcus crouched, ice axe in hand, and lined up his strike.
"One swing, eighty! One swing, eighty!"
Crack!
The thin ice shattered, revealing a dark opening leading who knows where.
We looked at each other. Marcus gulped and peered inside.
The flashlight beam reflected off the ice walls but revealed nothing in the darkness ahead.
He took a deep breath and went first.
"Stay behind me. If anything happens, I'll take the hit and you run!"
I punched his arm. "Some solidarity."
The passage started narrow and widened as we went. Before long, it opened into a vast underground space — as large as a plaza.
The ceiling arched dozens of stories above us, and Marcus and I walked through it like two insignificant ants.
Strange dark shapes of various sizes were frozen in the ice walls around us.
Some were basketball-sized. Others were as big as trucks.
I was scared and hurried to catch up with Marcus, sneaking glances with my flashlight.
A massive, gaping mouth lunged toward me. I recoiled, nearly tripping over my own feet.
"Holy shit! What is that?!"
Marcus spun around and instinctively stepped between me and whatever I'd seen. "What's wrong?"
I clutched my racing heart and looked more closely at the ice.
A complete white skeleton, as big as a small car, was frozen solid in the wall.
It looked like a dinosaur.
"A dinosaur?" Marcus swept his flashlight across it. "What would a dinosaur be doing in Antarctica?"
My heart was still hammering. "They've actually found dinosaur fossils in Antarctica before. They even found tropical plant fossils here. Who knows. Scared the life out of me anyway."
Besides the dinosaur, smaller skeletons were visible in the ice — some complete, others just fragments of bone.
This place looked like a giant morgue. A deep chill went through me, and I urged Marcus to keep moving.
"Are we going deeper?" I worried. "Why are there dinosaur fossils here?"
Marcus patted my head with a forced smile. "Don't worry, I'm here. Maybe in another half hour we'll be out.
"And besides, the deeper we go, the closer to the Earth's core, right? Should be warmer."
I rolled my eyes, but I was grateful for his optimism.
The frozen corpses in this ice cavern were too unsettling. We picked up the pace.
Then my flashlight caught something unusual on the wall ahead.
Most of the ice reflected light when illuminated, but this section seemed to absorb it — a patch of impenetrable darkness.
I nudged Marcus and pointed. "Look at that."
He shone his flashlight directly at the dark patch and frowned. "What is that?"
---
We aimed our flashlights at the dark patch on the ice wall. After several seconds, it began to move and rustle.
I rubbed my eyes. "Am I seeing things, or is that ice moving?"
Under the intense beam, the black surface writhed more rapidly, and a faint scratching sound reached our ears.
Then we realized — the black wasn't ice at all. It was something covering the ice, and now it was flowing toward us like water.
Marcus stepped back and grabbed my hand, his face paling.
"...What the hell is this?"
My skin erupted in goosebumps.
The black flood wasn't liquid. It was thousands upon thousands of wingless insects, each the size of a fingertip.
Black bugs, layered on top of each other, pressed together in a writhing mass.
The friction of their bodies produced a crackling sound that grew louder and louder as they surged toward us.
"Run!" Marcus shouted.
We turned and sprinted back the way we'd come. Forget the corpses — live bugs were a thousand times worse!
Marcus ran fast, shielding me from behind as we ran. "What the hell! Why are there mosquitoes in Antarctica?! Is there nowhere on this planet without bugs?!"
I gasped for breath. "I don't know! There are Antarctic midges, but they're only millimeters long and they eat algae! What are these things?"
The scraping sound behind us grew louder. I glanced back and nearly died of terror.
These things had several long, spindly legs and moved like spiders — fast!
They were already close behind Marcus!
I bit down and ran faster.
If I survived this, I was joining the track team for sure!
After about ten minutes of running, I heard a woman's scream.
"Ahhh—"
