The Mark Of The Three Stars

Once, in a far away place and a long ago time, a prince married a princess named Ariazaria who had the strange birthmark of three stars upon her back.
But the princess was kidnapped by a witch named Castrella who turned her into a horse to hide her and then sent a crow with a ransom note for the prince in its beak demanding a thousand gold guineas to be left in a well in a certain wood.
And so the prince sent the crow back bearing the message that the ransom would be paid in seven days but then he put on a ring given to him by his late aunt that could turn him into a hawk and he flew all over the land looking for his princess.
And eventually, he spotted a white horse tied up outside a cottage that had the birthmark of three stars upon its back and so turning himself back into his human form he knocked upon the door of the cottage.
It was the cottage of the witch who had kidnapped Ariazaria and it was she who answered the door to the prince.
Then he asked her, "That horse of yours has an interesting mark upon its back where did it come from?".
Lying, the witch replied, "Oh it was like that when I bought it. I don't know where it came from originally but if you wait inside my house I will find the name of the man who sold it to me".
And so he let the witch lead him into a room of her house that looked like it was for entertaining guests and he sat in a chair to wait.
But then the witch slammed the door of the room shut and locked it.
"What are you doing?", asked the Prince, startled.
"The room you are in is a magic room", said the witch, cackling, "It gets smaller and smaller until it crushes anyone who is in it and there is no way out".
At first the prince had no idea what to do and as, looking around him, he saw the room start to grow smaller, he thought his end had surely come but then he remembered his aunts ring and, slipping it back upon his finger, he turned himself into a hawk again and crawled out of the room through a tiny crack in the wall.
Listening from outside the door, the witch was quite surprised when she heard silence from within the room.
"Why isn't he screaming in fear?", she thought, scratching her hairy chin, "Why isn't he begging to be let out?".
And so the witch opened the door of the room and went inside to look around.
But while she was in the room, the prince, still in hawk form, flew in through a window of the house and, turning back into a man, slammed the door of the shrinking room shut behind the witch and then locked it.
"Let me out", cried the witch in horror.
"First you tell me something", said the Prince, "That horse outside your cottage? Is it the princess Ariazaria?".
"Yes", said the witch in a pleading voice, "Now let me out please".
"Not till you turn her back from a horse into a woman", said the prince.
And so the witch, because she had no choice, quickly said an incantation and the princess Ariazaria was transformed back into a human.
And when the princess entered the cottage looking for the prince and he saw her, he opened the door of the shrinking room and let the witch out.
After that, the witch was taken back to the palace of the prince and locked in a dungeon, her house and its evil room were burned to the ground and the Prince and his Princess lived happily ever after.
