The castle, once full of people, keeps its secrets. A huge stone building with huge halls, where various aristocrats used to hold balls in luxurious costumes, now looked abandoned, but so familiar...
Walking around the huge hall and imagining how people danced here, your legs swirled around the hall, imagining how you dance with them and not even noticing how a quiet hum of the wind appeared.
Myths about ghosts are not a joke. The hall is filled with a bunch of ghosts that dance a waltz, spinning the whole hall in inaudible music. Your eyes are closed, while your legs spin you in a kind of waltz without stopping, imagining a bunch of people in front of you.
When you stop and bow, a real ghost in a luxurious costume stands before your eyes and extends his hand to you in an offer to dance with him:
"Madam, may I invite you to a waltz?"
