Long ago, in a grand kingdom surrounded by forests and rivers, there lived a king with his twelve daughters. Each princess was beautiful, graceful, and clever in her own way. The eldest was calm and wise, while the youngest was cheerful and curious. The sisters shared everything and loved one another deeply. They slept together in a magnificent chamber lined with twelve velvet beds, and every night the king locked the chamber door himself.
Yet a strange mystery troubled the palace.
Every morning, the princesses awoke with their dancing slippers worn through at the soles, as though they had danced all night long. The king could not understand it. He checked the windows, the fireplace, and the walls, but there was no sign of escape. The chamber door remained locked until morning.
At first, the king questioned his daughters gently.
“My dear children,” he asked, “how do your slippers become ruined each night?”
The princesses smiled innocently and replied, “We do not know, Father.”
But the mystery continued. Night after night, the slippers were destroyed. The king grew worried and angry. He feared dark magic was at work inside his castle.
Finally, he made a royal proclamation throughout the land.
“Any man who can discover where my daughters go at night within three days and three nights shall marry one of them and become heir to my kingdom. But if he fails, he shall lose his life.”
Many princes came to try their luck. Each was welcomed warmly into the palace and given a room near the princesses’ chamber. Every evening, one of the princesses brought the prince a cup of sweet wine before bedtime.
Yet every prince failed.
They drank the wine, fell into a deep sleep, and awoke knowing nothing. On the third morning, their fate was sealed. Soon, fear spread across neighboring kingdoms, and fewer men dared to attempt the challenge.
Far away, an old soldier wandered through the woods. He had fought bravely in wars but was now poor and tired. One evening, while resting beneath a tree, he met an old woman carrying a bundle of sticks.
“You look troubled,” she said kindly.
The soldier sighed. “I have little money and no future. I heard of the king’s challenge, but many wiser men have failed.”
The old woman studied him carefully. “You seem honest and brave. I will help you.”
From her pocket she drew a small cloak.
“This cloak will make you invisible when you wear it. And listen carefully: do not drink the wine the princesses offer you. Pretend to sleep instead, and follow them wherever they go.”
The soldier thanked her warmly and traveled to the palace the next day.
The king welcomed him, though he doubted this tired old soldier could succeed where princes had failed. Still, the rules were the same.
That evening, the eldest princess brought him a silver cup filled with wine. The soldier secretly poured the wine into a sponge hidden in his sleeve while pretending to drink.
Soon he lay on his bed and began to snore loudly.
The princesses waited a little while. Then the youngest whispered nervously, “I do not think he is truly asleep.”
Her eldest sister laughed softly. “You worry too much. He sleeps as heavily as all the others.”
Then the eldest princess clapped her hands. At once, her bed moved aside, revealing a hidden trapdoor beneath the floor.
The soldier quietly pulled on the magic cloak and followed them unseen.
Below the trapdoor was a long staircase winding deep underground. The princesses carried lanterns that sparkled like stars. As they descended, the soldier accidentally stepped on the youngest princess’s dress.
She gasped. “Someone touched me!”
But the eldest sister replied, “It is only your imagination.”
At the bottom of the staircase lay an enchanted forest. The trees shimmered strangely. In the first grove, every leaf was silver. In the second grove, the leaves were made of gold. In the third, the leaves glittered like diamonds.
The soldier broke off a branch from each grove as proof.
The crackling sound startled the youngest princess again.
“Did you hear that?” she whispered fearfully.
But her sisters hurried onward.
Beyond the forests stretched a dark lake. Twelve handsome princes waited there in shining boats. Each princess stepped into a boat with her chosen prince, and together they sailed across the water toward a magnificent castle glowing with thousands of lights.
The invisible soldier slipped into the boat of the youngest princess. Her prince frowned as he rowed.
“The boat feels heavier tonight,” he said.
“It must be the warm weather,” she replied uneasily.
Inside the castle, music filled the grand halls. Crystal chandeliers sparkled overhead while servants carried trays of sweet fruits and shining goblets. The princesses danced happily with the princes hour after hour.
The soldier watched in amazement. To gather more proof, he secretly drank from one of the golden cups and hid it beneath his cloak.
The youngest princess remained nervous all night.
“I feel as though someone is near us,” she whispered several times.
But her sisters laughed and continued dancing.
At last, near dawn, the princesses’ slippers were worn thin. The music faded, and the twelve sisters returned across the lake, through the glittering forests, and up the hidden staircase to their chamber.
The soldier raced ahead and lay back in bed just before the eldest princess closed the trapdoor.
For three nights the same thing happened. Each time, the soldier followed them and collected more evidence.
On the third morning, the king summoned him to the throne room.
“Well,” said the king, “have you discovered my daughters’ secret?”
“I have, Your Majesty,” replied the soldier calmly.
The twelve princesses turned pale.
The soldier described the hidden staircase, the silver, gold, and diamond forests, the lake, the underground castle, and the princes with whom the sisters danced every night. Then he showed the king the three shining branches and the golden cup.
The king stared in astonishment.
“Daughters,” he said sternly, “is this true?”
The princesses hung their heads. At last, the eldest spoke.
“Yes, Father. We cannot deny it.”
The king was relieved that the mystery had finally been solved. According to his promise, the soldier could choose one of the princesses to marry.
The soldier, being thoughtful and modest, chose the eldest princess because she was wise and kind.
A magnificent wedding was held that lasted many days. Music echoed through the kingdom, and the people celebrated joyfully. In time, the soldier became a respected prince and later ruled the kingdom with fairness and wisdom beside his queen.
As for the twelve princesses, they never again traveled to the underground castle. Yet they often remembered the magical nights of dancing beneath the earth, where silver leaves shimmered and music played until dawn.
