The ocean was serene that night, the waves gently lapping against the Bio Lab expedition vessel as it drifted in the deep waters, far from the shore. The team had been scanning the seabed, gathering marine samples and tracking aquatic life for their ongoing research. Everything seemed routine, the ocean's secrets flowing steadily into their machines and instruments—until something strange happened.

A sudden, violent tug on one of the nets jolted the crew from their monotony. The net was struggling, as if it had caught something much larger than intended. Alarmed, the crew rushed to the edge of the boat, their movements frantic as they hoisted the heavy net out of the water.

As the net broke the surface, they could barely believe their eyes.

Caught in the tangled mass was a figure, thrashing, her iridescent scales shimmering in the moonlight. Gasping, they realized what they had captured wasn't a sea creature—it was a mermaid. Her long tail was wrapped in the netting, her luminous eyes wild with both panic and fury. She fought against her bindings with a ferocity the team had never seen before.

"Get her out of there—now!" one of the researchers shouted, breaking the stunned silence.

They worked quickly, hauling her into the ship's massive, transparent holding tank—a cylindrical aquarium designed for larger marine species. The mermaid slammed against the glass in desperation, her fists pounding the clear barrier as the water swirled around her.

Inside that glass prison, her expression was a mix of disbelief and anger. How could this have happened? After years of evading the humans, she had been careless for just a moment. And now, here she was—trapped. Vulnerable.

Back at the Bio Lab headquarters, the discovery spread like wildfire. A mermaid—a living, breathing mermaid, something no one had ever seen in the scientific world—had been captured. This could be the breakthrough of the century. Yet, amid the excitement, an undercurrent of unease rippled through the sirens who worked covertly within the lab. They knew this wasn't just any mermaid. One of them immediately contacted the only person who needed to know—Xrythe.

Far across the world, Xrythe Van Hyrenn was on a business trip in Korea, attending a high-profile meeting when her phone rang. She answered with a curt tone, irritated by the interruption.

"What is it?" she demanded, her voice sharp as glass.

The voice on the other end, one of her closest and most loyal siren operatives, spoke with a measured calm, but beneath it was something more—urgency.

"Xrythe, we've caught something... No. Someone," the voice said.

Xrythe's irritation evaporated, replaced by a cold intensity. "What do you mean, someone?"

There was a brief hesitation before the siren on the other end delivered the news that would change everything. "It's her. Obesin's daughter."

The name—Obesin—struck her like a lightning bolt. Centuries of buried pain and rage ignited within her, flooding her mind with memories she had long suppressed. The betrayal. The curse. The destruction of her people. And now, the daughter of the one who had orchestrated it all was in her grasp.

For a moment, she couldn't speak, her mind racing with possibilities. Finally, her voice, cold as the deepest part of the ocean, came through the receiver.

"I'm coming back. Immediately."

Xrythe abandoned her business in Korea without a second thought. Within hours, she was aboard a private jet, slicing through the clouds on her way back to the United States. Her mind was a storm of emotions—rage, vengeance, and the quiet simmering of something darker, more calculated. Centuries had passed since she had even heard Obesin's name, and now, his bloodline was in her hands.

This was more than fate—it was an opportunity she had waited lifetimes for.

When she finally arrived at Bio Lab's headquarters, the energy in the facility shifted the moment she stepped through the doors. At 6'11", she towered over most of the staff, her long black hair flowing loose behind her, her sharp features and piercing red eyes commanding fear and respect. No one dared approach her as she made her way directly to the holding area.

The air was thick with tension as she entered the room where the mermaid was kept. The massive cylindrical aquarium stood at the center, filled with water, illuminated by harsh, sterile lights. Inside, the mermaid floated, glaring at the scientists who monitored her every move.

Xrythe paused in front of the tank, her expression unreadable, her hands clasped behind her back. For a long moment, she simply stared at the mermaid—the daughter of Obesin. The one being who could open the door to her long-sought revenge.
