Far-far away, in the land where the sea kissed the jagged cliffs, and the winds whispered ancient tales, there lived a Selkie named Eithne. Her name, meaning "fire," was as fitting as the sun's first rays that would light up the dark depths of the ocean at dawn. Eithne was known throughout the coastal villages as the most beautiful and mysterious of the Selkies, a creature of both land and sea, whose heart swayed between two worlds. Her sealskin, dark as midnight, was the key to her transformation, yet it was also the tether to her soul.
Eithne's home was beneath the waves, where the ocean sang songs of forgotten gods and the deep. Her people, the Selkies, lived among the creatures of the sea, never truly part of the human world but forever connected to it. They were powerful, with the ability to shapeshift from seals into humans. The Selkies, though, never remained long on land; the sea always called them back, its tides and rhythms as essential to their nature as air to man.
It was during one of the rare seasons when Eithne ventured to the shores of a secluded bay that she met him - a man named Cormac, a mortal whose reputation had spread across the lands. Cormac was a warrior, brave, handsome, and ambitious. His quest had brought him to the cliffs of Eithne's home, where tales told of an ancient weapon of great power, known as
The Sword of the Deep. Forged in the fires of the gods and hidden beneath the sea, it was said to grant immense strength to its wielder, enough to overthrow empires. Cormac sought the sword, and he had heard whispers that a Selkie could guide him to it.
At first, Eithne laughed at the mortal's foolishness, for no mortal should dare to seek such a thing. Yet something stirred within her - a hunger for adventure, a longing for a life beyond the waves. For centuries, her people had been cursed to live at the edge of both worlds, never fully part of either. Eithne was no different, drawn to the land and its fleeting, passionate existence. When Cormac promised to return her to the sea if she aided him, a dark temptation took root in her heart.
Under the light of the full moon, Eithne agreed to help Cormac, knowing the risks, yet unable to resist the allure of the human world and the thrill of a journey she had never known. She led him to the ancient underwater caves where the sword lay guarded by creatures of the deep - serpents with eyes like burning coals, and leviathans that could devour ships whole. The path was treacherous, but Eithne knew the way, her spirit intertwined with the ocean's pulse.
For many days, they navigated the labyrinthine tunnels beneath the sea. Eithne could feel the pull of the tides and the weight of ancient magic growing stronger with each passing moment. Cormac was determined, his resolve unwavering. But as they neared the chamber where the sword lay, Eithne's heart wavered. She felt a deep stirring, as though the ocean itself was warning her of something dire. Yet, her ambition overshadowed her doubt. She had never before been so close to the land's promise, the mortal world that she had only glimpsed from afar. She wanted to belong, to be free of the eternal cycle of tides.
The chamber was vast, and at its center lay
The Sword of the Deep, embedded in a rock, glowing with an otherworldly light. Cormac stepped forward with a look of awe. But Eithne stood back, watching him. She felt the sea calling to her, urging her to turn away, but her feet were rooted to the spot.
Cormac reached out to grasp the sword, but as his hand touched its hilt, the water around them began to churn violently. The leviathans had awakened. The sea, in its wrath, seemed to punish them both for their trespass. Eithne's heart raced, and she could feel the deep currents pulling her away, trying to drag her back to safety.
But Cormac was relentless. His grip tightened on the sword, and in a moment of fury and greed, he turned to face Eithne. He had no intention of sharing the sword with her. "I will not return you to the sea," he hissed. "You have helped me to claim this power, and now you will help me to wield it."
Eithne's heart shattered as his words struck her like a blade. In that moment, she understood the true cost of her betrayal - not just to the sea, but to herself. Cormac had never cared for her; she was merely a tool to him, a means to an end. Her promise had been her undoing. The ocean itself seemed to echo her sorrow, as the waves roared in fury.
With a final, defiant roar, the sea's creatures surged forth, and Cormac was engulfed by the depths. He had failed to realize that the sword was not meant for mortals, and his greed had led him to his doom. Yet Eithne did not feel relief. She did not feel triumph. She felt only a deep, aching emptiness.
Eithne wept, her tears mingling with the salt of the sea. She had broken the sacred bond between her people and the ocean, and now the sea would never forgive her. She had been promised freedom, but she had instead gained nothing but a curse. As the tides calmed, the underwater caves seemed to close behind her, sealing her fate. The sword had disappeared, its magic fading into the depths, and the ocean was quiet once more.
Eithne returned to her sealskin, but her heart was heavy with regret. She knew that her betrayal would echo for eternity. She had sought power, and in doing so, she had lost the very thing she had longed for: a place to truly belong. The sea, which had once been her refuge, would never embrace her again.
And so, Eithne wandered the coasts, never fully part of the land, never fully part of the sea. Her heart beat with the rhythm of the waves, but her soul remained fractured. She was the betrayed and the betrayer, a shadow of the Selkie she once was.
The legend of Eithne, the Selkie who betrayed the ocean for a taste of mortal power, is told in whispers along the shores, where the sea's roar is sometimes heard to carry her sorrow. They say that if you listen closely on a moonlit night, you may hear her singing her lament, forever caught between two worlds, never truly free. And so, her tale is known as
The Betrayal of Eithne: The Seal's Curse, a cautionary story passed down through the ages, warning all who would dare to trade the ocean's gift for the fleeting promises of land.
