Rarity awoke to an ominous thump which came from deep within her store. She pulled off her night mask with her magic, and caused a faint blue light to emit from her horn.
She quietly walked down the hall to check on Sweetie Belle, and noting that she was still asleep, closed her door and placed a quick ward on it for safekeeping.
She crept down the staircase into the main part of her store. The outside door was wide open, letting in the night air. She closed the door, and proceeded to her workroom.
On the floor, in front of her sewing wheel, was a young woman in a white and grey dress with a brown hooded cloak. She seemed to be fast asleep. Rarity sighed and tapped her with a hoof. She stayed asleep. After shaking her fairly vigorously in her magic without effect, she laid the woman on her fainting couch.
She locked the door from outside, and walked at a fast pace to Twilight's castle. She entered, and worked her way through the hallways to Twilight's bedroom. The noise of her hooves beating against the stone floors woke Twilight up.
"I had an intruder last night," said Rarity. "She seems like one of those creatures you described from the other side of the mirror, but she is fast asleep and I was unable to awaken her."
Twilight teleported the pair to just outside of Carousel Boutique, and Rarity opened the door. She led Twilight to the sleeping figure.
Twilight cast a few spells on her, then, with a shocked look on her face said, "She is suffering from a curse."
"I thought you were through with curses after that whole zebra incident?" said Rarity.
"No," said Twilight. "It actually led me to a pretty thorough study of them. If my diagnostic spells are correct, the only way to wake her is by a kiss from a prince."
"But the only unmarried prince in all of Equestria is," said Rarity.
"Blueblood," said both ponies with a hint of disgust in their voices.
