Chapter 3: The Silent Cruise of the Abyssal Leviathan

When a true Abyssal Leviathan moves, there is no thunderous roar, nor is there a spectacular splash.

The most terrifying aspect of these ancient behemoths is their absolute silence. They are so unimaginably massive that they don't need to hunt; their sheer displacement of the currents is enough to create localized vacuums, sucking in every careless fish and fragile skiff in their path.

In the lowest level of the Emerald Lighthouse—a submerged observation deck known as the "Depth Chamber"—the thick quartz windows were groaning under immense pressure. The silver-gray mist of the upper sea did not reach down here; there was only a suffocating, ink-like darkness.

Pickle Cat stood before the curved quartz glass, his emerald reflection faintly glowing in the dark. Beside him floated a spherical brass automaton, its surface covered in clicking gears and glowing dials. This was his "Brass Arbiter," a magical construct capable of calculating the weight and pull of the deepest currents.

"Pressure dropping rapidly in quadrant East-Seven, Teacher," the Brass Arbiter reported, its synthetic voice devoid of emotion. "The ambient starlight is being drained. A vacuum is forming."

"It's here," Pickle Cat whispered, his paws resting lightly on the cold quartz.

He didn't need to look at the dials. Through his padded paws, he could feel the ancient, rhythmic thrumming echoing through the bedrock of the ocean floor. It was the heartbeat of the Leviathan.

Slowly, a shadow detached itself from the absolute darkness outside the window. It was so colossal that the eye couldn't comprehend its shape all at once. First, a section of ribbed, metallic-looking hide drifted past, easily the size of a floating city. Then, a massive fin cut through the water, dragging behind it a swirling vortex of violently compressed green and red light.

As the Leviathan cruised past the lighthouse, the ocean seemed to hold its breath. All the ambient starlight in the surrounding waters was instantly sucked toward the beast's massive form, leaving the area in a temporary state of absolute void.

If any foolish navigator had anchored their ship directly above this path, hoping to catch the beast's attention, the sudden vacuum of light would have snapped their keels in an instant, dragging them into the abyss without a single ripple hitting the surface.

"Calculate the wake, Arbiter," Pickle Cat ordered, his eyes tracking the fading shadow of the behemoth.

"The vacuum will collapse in forty-two seconds, Teacher," the brass sphere clicked furiously. "Following the collapse, a massive upward surge of emerald currents will occur. A true Green Tide."

Pickle Cat turned away from the window, a satisfied smirk lifting his emerald whiskers. He walked over to the transmission pipes that connected to the upper tower.

"This is the golden rule of the deep, my friends," he said, pressing a button that would broadcast his voice to the special receivers held by his 'Missionaries' across the sea. "You never stand in front of the Leviathan to stop it, and you never swim directly above it to ride its back. You wait for it to pass. You let it endure the friction of the dark waters."

He tapped the pipe with his claw, emphasizing his point.

"Prepare to hoist the sails. The vacuum is ending. We ride the wake."
