Long time ago, in the deep, forgotten reaches of the lochs and glens, where the mist clings to the surface of the water like a whispered secret, there lived a Kelpie named Catriona. Her coat shimmered with the night sky's blackest hues, and her eyes held the stormy glow of an ancient fury. Catriona was no ordinary Kelpie, for she had tasted the bitterness of betrayal, and it was this bitter seed that grew within her heart.
Catriona's life, once peaceful, had been turned upside down by a cruel act, one perpetrated by none other than a human - a philosopher of considerable renown. He was known as Feran, a man whose name was spoken in awe by those who knew of his intellect, though few truly understood the depth of his work. Feran had long sought the secret of immortality, and his obsession led him to ancient texts, spells, and forgotten rites.

Captured in the soft light of dawn or sunset, this white horse with its delicate pink mane races through the water, creating a moment of natural beauty and freedom.
Through dark alchemy, Feran believed he had discovered a way to transmute the very essence of life into a tangible form - something far more precious than gold. It was a stone he called the Philosopher's Stone, an object of such power that it could bestow upon its possessor not only endless life but also the ability to turn any metal to gold. Feran, however, was not content with the stone's creation alone; he wanted the power to transcend mortality, to bind the very elements to his will.
But the Philosopher's Stone came at a cost.
Catriona, a creature of the water and the earth, had once been his ally. She had lent her magic to his research, guiding him through the hidden paths that led to forbidden knowledge. It was she who had first whispered the secret of transmutation into his ear, a secret that was passed from the ancient ones who roamed the earth before humans knew how to speak. In return for her help, Catriona had asked for only one thing - a bond. A promise that when the Philosopher's Stone was forged, she would have a place within its power, for she had long desired the freedom to travel beyond the lochs, beyond the waters, to roam the world without the chains of her kind.
At first, Feran had promised, speaking with the sweet words of a man in need. He swore that the stone would grant them both what they desired: eternal life, boundless power, and the freedom to move as they willed. But when the stone was finally complete, and the elixir of immortality lay before him, Feran broke his word. Instead of sharing the power of the stone with Catriona, he sealed it away for himself. He locked it in a vault beneath his tower, declaring that it was too dangerous to share.
And thus, Catriona was cast aside, her trust shattered, her dreams dashed upon the rocks of betrayal. For many years, the Kelpie wandered, heartbroken and consumed by a thirst for vengeance. She no longer cared for immortality or the stone. She cared only for one thing: Feran would pay for his treachery.
The time came when the philosopher's own hubris turned against him. Feran, in his madness, grew restless with the power of the stone. He believed it could do even more than he had ever imagined, and so he pushed its limits. He made a mistake - a terrible mistake. The Philosopher's Stone, forged by magic too old for even the gods to understand, began to unravel the fabric of reality itself. Feran's tower, once a place of knowledge, became a prison of chaos, a place where the laws of nature bent and snapped like broken branches. The very earth beneath his feet trembled.
In his final days, Feran sought out Catriona, calling to her through the tempest of his own making, begging for her aid. The stone had turned on him, draining his life force and twisting his mind. He needed her help to escape the grip of his own creation.
Catriona, with eyes that burned like the storm-swept seas, appeared before him at the edge of the loch. Her coat glistened with the rain, and her breath steamed in the cold air. The Kelpie, once a creature of silent beauty, now bore the mark of wrath in every motion.

Surrounded by mist and a quiet sky, White Sorcha’s movement cuts through the water like a vision, the foggy atmosphere adding an almost dreamlike quality to this breathtaking scene.
"You come to me now," Catriona said, her voice a whisper that echoed across the water. "After all these years, after you left me to rot in the shadows of your greed, you now seek my help?"
Feran fell to his knees, tears of desperation mixing with the rain. "I was wrong," he said, "but the stone - it is destroying me. Please, Catriona, you are the only one who can save me."
Catriona's laugh was a hollow, cold sound. "Save you? You who promised me the world and gave me nothing but lies. You who used me as a tool to fulfill your own selfish desires."
For a moment, Feran's pleading eyes met Catriona's unyielding gaze. In that moment, he understood what he had done - not just to her, but to the world. The power of the stone had corrupted him, and now he saw clearly the price of his ambition.
But Catriona, knowing his weakness, allowed the full weight of his guilt to sink into his soul. She turned away, and as she did, the waters around the loch rose, churning in response to her sorrow and fury.
"I gave you everything," she whispered, her words heavy with centuries of grief. "And now you will face the same fate as those who betrayed the earth itself."
With a flick of her tail, the loch surged forward, the waves crashing into Feran's tower. The water, once calm and serene, now roared with the fury of a thousand storms. The tower crumbled beneath the relentless tide, and Feran was consumed by the waters he had once sought to control.

In a forest cloaked in mist, a white Catriona stands gracefully, embodying enchantment and mystery. This tranquil setting invites one to explore the hidden wonders of nature through the soft embrace of fog and towering trees.
Catriona watched, her heart both cold and filled with a strange satisfaction. The philosopher's stone, left forgotten and abandoned, slipped from the wreckage and sank into the depths of the loch. It was lost to the world forever.
And so the tale of Catriona, the Kelpie of vengeance, became one whispered by the winds and carried on the waters. She had sought no glory, no riches, but only the justice that the gods themselves had denied her.
Though she still roamed the lochs, her heart was no longer heavy with the thirst for revenge. For in her heart, she knew that the true power was not in immortality or gold, but in the ability to choose one's own fate - and in the end, she had chosen hers.
