Creepy town

Another time, at dusk, exceptionally tired but happy, Twilight Sparkle and Rarity were returning home from Pinkie's party. Luna's darkness had been slowly claiming the whole sky, despite Pinkie's wish for their way to be easier, in the rain that was happening because of pegasus holiday the day before. They went on through multiple town districts, where street lights were lighting up slightly where Twilight wanted to go. And so they were destined to eventually reach Rarity's shop. But something happened.

In the area among broken street lights, Rarity stepped into a sinister hole that they didn't remember ever being there. The hole didn't give any warning before that happened. Rarity fell into the dirt.

Then, with Twilight's magic, weakened from tiresome partying, she was back. Twilight prepared to seal the hole using transformation spell. But Rarity ran away without a word. It wasn't too far from Boutique, so Twilight expected to be there shortly. Twilight wanted to say curse words addressed to the hole, but it might already be cursed. It was more practical to terminate it.

Then, after quickly passing some streets in the rain, Twilight saw the destination. Of course, the door was open, because it's convenient for this story.

She just went inside.

And then she heard a sound from upstairs. It went on continuously. Twilight thought it was a washing machine. "I'm here" - purple unicorn announced.

"Wait in there!" - Rarity shouted.

And then some time passed. Then some more. "Ouwww!!" - in a hurry, Rarity accidentally fell. "i-iits alriight!.."

Then Twilight came. Rarity would shout, but it was too late. To prevent That from happening.

Twilight found Rarity. Without skin or hair. Not even on face. She stood up by now, but looked like a horrific ghoul.

"What in Celestia's dominion is happen-ing!" - Sparkle whined. "Rarity! It's you, and where is-"

"It's being washed," - Rarity said with sadness. "I would blame you for being here now, because you shouldn't ever be and see this," - she admitted, "but I should be blaming myself for not being able to stand that much dirt. It's the cursed hole that did this to me." - "But this is how I work. The other set is completely torn, otherwise I would instantly wear it. I was unlucky this whole week. I'll need two days to weld it."

"Maybe you're cursed," - Twilight deduced, - "Let's go to Zecora?"

"No, that's it. We had an argument, and she cursed me."

"In such way?" - Twilight protested, "She would never..."

"Unless she was cursed herself; ... though, you don't understand. I live like this for a decade already. I'll have you know that it gets dirty very easily, much harder to clean than regular skin. It's quality skin substitute. I have to buy material about every year, and it's very expensive. A fourth of my gems goes for that. It hurts that half a country thinks I live a happy life and have no problems. I have. Sewing this. Replacing hidden zip lines. And keeping it from Sweetie Belle."

"I'm sorry. So I... should I wait for you outside and then we go fix the curse?.."

"That's not tonight. But you can stay tonight in the Boutique while I try to fix this, if you want."
