The Deep Awakening: Secrets Beneath Apolaki

Chapter 3: The Sunken Door

The next morning came with a strange silence. The sea was calm again, too calm—like the storm had passed but forgot to take its shadow. The crew of the Luntian gathered on deck, tired, confused, and quietly afraid.

Elias stared at the horizon, coffee untouched in his hand. The glowing water had faded overnight, leaving no trace except for the strange circular waves that still moved faintly across the surface.

Lira broke the silence.

“Headquarters wants us to suspend the dive,” she said. “They said the readings are unstable.”

Rog snorted. “Unstable? That’s one way to put it. We almost lost the sub yesterday.”

Elias didn’t answer right away. He kept his eyes on the calm blue sea. “If we leave now,” he said softly, “we’ll never find out what’s under that crater.”

Lira frowned. “You saw the same footage I did. That structure isn’t natural, Elias. It’s manmade—or worse, something older.”

Elias turned to her. “Exactly. Don’t you want to know who—or what—built it?”

There was a long pause. The hum of the ship’s engines filled the air. Finally, Rog sighed and rubbed his temples.

“Alright,” he said. “One last dive. But we do it safely. If something feels off, we pull out. Agreed?”

Elias nodded. “Agreed.”

By midday, the Aguinaldo-4, a newer and more durable submersible, was lowered into the water. This time, Elias and Lira decided to go down themselves. Rog stayed on the surface, watching their monitors with a worried look.

Inside the sub, the hum of the descent was steady, almost soothing. The deeper they went, the darker the world became. Sunlight vanished completely after a few hundred meters. Soon, all they could see was what the sub’s lights revealed—a ghostly world of stone, silence, and shadows.

“Depth: 10,000 meters,” Lira said, checking the readings.

Elias’ voice was calm but tight. “Stay close to the ridge. We’ll follow the sonar path toward the crater’s center.”

As they descended further, the pressure gauge crept higher. Outside, small jellyfish floated like drifting stars. The water shimmered faintly around them, giving off a pale green glow.

“That’s the same light we saw last night,” Lira whispered.

Elias nodded. “Bioluminescence maybe… but too strong. Something’s feeding it.”

At 32,000 feet, the sonar pinged. They had reached the bottom of the Apolaki Caldera.

The view took their breath away.

Stretching before them was an enormous circular valley—a smooth basin surrounded by high cliffs of black volcanic rock. In the middle lay the door they had seen in the footage. It was massive, perhaps 200 meters tall, curved like a half-moon, covered in faint carvings that looked worn by time and heat.

Lira leaned forward, eyes wide. “That’s… impossible. It’s perfectly shaped.”

Elias turned the lights to full power. “It’s not just a door,” he said. “It’s an entrance.”

They moved closer, the sub’s beams gliding across the carvings. The patterns looked almost like waves—spirals that wrapped around symbols shaped like eyes and suns. In the center of the structure, a circular emblem glowed faintly blue, pulsing like a heartbeat.

“What’s that symbol?” Lira asked.

Elias hesitated. “It’s ancient. I’ve seen something like it before… on carvings found near Benham Rise. Dr. Barretto mentioned it in her notes.”

Lira’s eyes flicked toward him. “You mean Dr. Jenny Anne Barretto? The one who discovered the caldera?”

“Yes. She believed Apolaki wasn’t just a volcano—it was part of something much bigger. She once wrote that the Philippine Rise might have been a sunken continent.”

Lira blinked. “You think this could be a remnant of that?”

Elias didn’t answer. He didn’t have to. The idea hung in the water between them—unspoken, but heavy.

Then the lights flickered.

“Elias…” Lira’s voice was tight.

“I see it,” he said. The sub’s power meters dipped for a second before returning to normal. “Could be interference.”

But it wasn’t.

A low rumble echoed through the water. The ground beneath the sub trembled, and tiny rocks floated upward in slow motion. The blue glow in the emblem brightened, pulsing faster now—like it was responding to their presence.

Suddenly, a deep vibration filled the cabin. It wasn’t random. It came in bursts—three long pulses, a pause, then two shorter ones.

“Is that… Morse code?” Lira asked, her voice shaking.

Elias stared at the console. “No. It’s older than that.”

The door began to shift.

Slowly, the cracks along its edge started to glow, lines of light spreading outward like veins. The rock moved with a deep grinding sound, releasing clouds of silt. A gust of bubbles and heat erupted from the base, shaking the sub violently.

“Back up! Back up!” Rog’s voice screamed through the radio. “Something’s happening down there!”

Elias fought the controls, but the current was too strong. The sub was pulled forward, closer to the massive door. The light grew brighter, filling the entire camera feed.

Then, with a sound like thunder beneath the sea, the door opened.

Behind it was darkness—deep, endless darkness. But not empty. Shapes moved inside it, slow and graceful, too large to be fish.

Lira gasped. “Are those… creatures?”

Before Elias could answer, one of the shapes glided closer. It was massive, shimmering faintly like molten metal. Its eye—if that was an eye—glowed gold for a moment before vanishing into the dark.

The radio crackled again. Rog’s voice was panicked. “Elias! Get out of there now! The readings are off the charts!”

The currents shifted again, and suddenly the door slammed shut, sending a shockwave through the water. The sub spun out of control before Elias managed to stabilize it.

When the dust cleared, the blue glow was gone. The door stood still again, silent, cold, and unmoving.

But the sonar showed something new—a signal, faint but steady, coming from deep within the caldera.

Lira’s hands trembled. “That’s coming from inside.”

Elias swallowed hard. “Then whatever’s in there… knows we’re here.”

Hours later, they surfaced. The crew rushed to help them out, pale and shaken. Rog didn’t speak for a long time. When he finally did, his voice was low.

“I told you that place was alive.”

Elias sat on the deck, staring at the sea as the sun set in blood-red light.

He thought of Dr. Barretto again, of her last expedition before she disappeared years ago. No one had ever found her final research log.

Now he understood why.

The ocean wasn’t just hiding the past—it was guarding it.

And they had just knocked on its door.
