In the ancient days of the Sultanate of the Indies, a poor but honest fisher named Abdullah worked the waters of a strange black lake nestled between two barren hills. One evening, he cast his net into the inky depths and felt an unusual weight. Hauling it up with great effort, he discovered not a glittering catch of fish but a young man whose lower body had been transformed into polished black marble, while his upper torso and noble face remained human, though etched with years of silent anguish. The palace behind the shore stood eerily silent, its courtyards choked with weeds and its fountains dry. Trembling, the fisher asked the youth how such a calamity had fallen upon a king. The young man fixed his gaze on the horizon and spoke with a voice hollowed by grief. 'This was no ordinary misfortune,' he said, 'but the deliberate work of sorcery and conjugal betrayal.'

The king, whose name was Shah Zaman, had been the ruler of the prosperous Black Isles, a land of flourishing orchards and bustling trade. He married his cousin, a woman of extraordinary beauty, but soon discovered that she harboured a secret lover from a distant land. Each night, while the king slept, she would drug his food so that he fell into a deep slumber, then she would slip away to meet her paramour. When Shah Zaman finally learned the truth, his heart was torn between rage and disbelief. He confronted his wife, but she denied everything, instead accusing him of jealousy. The queen, a skilled enchantress, decided to silence him forever. Using forbidden magic, she transformed the entire city into a vast black lake and its inhabitants into fish of four colours: white, red, blue, and yellow. The king herself she struck with a spell that turned his legs to marble, leaving him imprisoned in the palace, half a man and wholly helpless.

For many years, Shah Zaman remained thus, a monument to betrayal and magical cruelty. Each morning, the queen would visit him and beat him with a leather strap, cursing him for his suspicions. She revelled in his pain, and her power grew stronger with his despair. The fisher, listening in horror, could scarcely believe the depth of such wickedness. In his own simple life, he had known hardship but never such calculated malice. The king explained that the queen kept a magical talisman that maintained her enchantments; without it, she would lose her power. Yet he was powerless to retrieve it, chained as he was to his marble pedestal. The fisher, moved by compassion and a sense of justice, offered to help. 'Tell me where this talisman lies,' he said, 'and I shall do what I can to restore you.'

Using forbidden magic, she transformed the entire city into a vast black lake and its inhabitants into fish of four colours: white, red, blue, and yellow.

But the king hesitated. To recover the talisman would mean entering the queen's private chambers, a place forbidden to all men save the king himself. The fisher, being a commoner, would risk immediate execution if caught. Moreover, the king wrestled with the ethics of revenge: was it just to punish his wife so severely, even after her monstrous acts? Yet her crimes were not against him alone but against an entire kingdom. The fisher reminded the king that mercy without accountability could breed further tyranny. After a long silence, Shah Zaman agreed. He instructed the fisher on the location of the talisman — a secret compartment behind the queen's mirror. The fisher, though afraid, resolved to act. That night, under cover of darkness, he crept into the palace, his heart thudding against his ribs.

The fisher found the talisman: a small onyx box inscribed with ancient runes. As he lifted it, a cold energy surged through his hands, and he knew he held the fate of the Black Isles. He carried it back to the king, who instructed him to open the box and break the seal within. The moment the seal broke, a great tremor shook the palace. The marble that encased the king's legs cracked and fell away, and colour rushed back into his skin. Outside, the black lake receded, revealing green meadows and bustling streets. The fish transformed back into the citizens, each colour returning to its former tribe. But the queen, feeling her magic dissolve, rushed to the palace, her face contorted with fury. She saw the king standing, whole and restored, and she knew she was defeated.

Shah Zaman now faced his greatest ethical test. Should he execute his wife outright, or show mercy? The fisher, having witnessed the queen's cruelty, argued that justice demanded a proportionate response. The king, remembering the years of torment, chose a path that balanced retribution with restraint. He stripped the queen of her magical powers and banished her to a remote desert island, forever separated from her lover and her former life. He did not kill her, but he ensured she could never harm another soul. The city rebuilt itself, and the fish became people once more, each colour representing a different faith or tribe that had been united under the king. The young king of the Black Isles had transformed not only physically but morally, learning that true leadership requires both strength and compassion.

The fisher returned to his humble trade, rewarded with treasure and thanks, but he carried with him a deeper understanding of power and its perils. Shah Zaman ruled wisely for many years, his earlier suffering making him a more empathetic monarch. The tale of the Black Isles spread across the Sultanate, a warning against betrayal and a reminder that even the most cruel enchantment can be broken by courage and ethical clarity. The young king's voice, once silenced by despair, now spoke for justice. His transformation from victim to ruler, from marble to flesh, echoed the transformation of his kingdom from a black lake to a land of colours. And the ethical tension between revenge and mercy remained a delicate balance, one that every leader must navigate.
