High above the Alme River, where the mist drifts over the valley like a veil every morning, once stood a mighty castle – Büren Castle.
Built of cold stone and surrounded by water, it was the home of the noble von Büren family, known for their bravery – but also for the darkness that accompanied them.
It is said that the last lord of the castle was Gerhard von Büren, a man of honor but plagued by troubled dreams.
Night after night, he saw the same dream: A woman dressed in white stood on the castle walls, weeping.
No one knew who she was until one day an old villager revealed the secret:
It was Alena, Gerhard's sister, who had disappeared long ago under mysterious circumstances.
According to legend, Alena was in love with a knight from Paderborn—a hostile land.
When her brother learned of this, he had the knight executed and Alena locked in the castle cellar—"until she forgets."
But she never forgot.
It is said that she died in darkness, praying that her spirit would not find peace as long as the von Büren blood flowed in the castle.
From that time on, the castle grew restless.
Doors opened of their own accord, candles went out without wind, and quiet sobs echoed through the corridors.
One winter, Gerhard descended into the cellar, determined to face his family's curse.
He never returned.
The servants found only a silver spear, embedded deep in the stone, and a pale figure of the woman, who vanished into the mist.
The castle has stood empty ever since.
Only the brave dare to descend into the cellars, and if you listen closely, you can hear two voices—
the whisper of a sister and the sigh of a brother,
trying to forgive each other among the cold stones of a castle that even time could not free.
