It had been a day since the Summer Sun Celebration was nearly derailed by the invasion of the plunder vines. Thankfully, our heroines managed to defeat them and things returned to normal. Twilight Sparkle awoke planning to spend another day isolated in the library from the world which despised her. However, Sunset Shimmer tempted her with the library in the Castle of the Two Sisters and Twilight couldn't resist. The two ponies and Spike headed to the castle soon arriving and entering the library. Sunset Shimmer had a saddlebag with her.

"Wow! Look at all these ancient books! It's a veritable gold mine of information!" declare Twilight jubilant.

"What a dork." snorted Sunset jokingly.

Twilight grinned a bit, knowing Sunset was being lighthearted.

"At least you think she is." whispered the voice.

"Not again." moaned Twilight softly.

"Did you say something?" asked Sunset.

"I said this place is perfect." answered Twilight, with a false smile.

"Let's get started." said Sunset.

"Sure." agreed twilight.

Sunset Shimmer began to sort books with her magic.

"Hopefully, this will take my mind off things." thought Twilight hopeful.

Twilight threw a book open and began to read.

"Are you okay?" asked Sunset Shimmer.

Twilight let out a sigh knowing Sunset only wanted to help.

"I'm okay." answered Twilight.

"Being in your situation must be unbelievable difficult." noted Sunset.

"Everything seemed okay when I was freed." sighed Twilight.

"Emotions where running high." stated Sunset.

"What does that have to do with anything?" asked Twilight confused.

"The girls do care for you. Their expressions of friendship and jubilation that they showed after you where freed are true." answered Sunset.

"If that was so, then why do they hate me now?" asked Twilight sadly.

"They've heard the horror stories of family members hurt under Sombra's rule." answered Sunset.

"Which I helped in." noted Twilight somberly.

Twilight sadly shook her head.

"They told me themselves they don't hate you." added Sunset.

"Thanks." replied Sunset softly.

The two shared a kiss.

"Sunset is so nice to lie about my friends not hating me. She really wants to protect me." thought Twilight.

The two ponies began to ready while Spike anxiously looked around worried about the creepy old castle. They didn't realize Applejack, Rainbow, Rarity and Fluttershy arrived at the castle. The former duo where seeing who was braver while the Fluttershy was accompanying Rarity to retrieve tapestries. As it got darker, Sunset and Twilight used candlelight to see.

"Find anything?" asked Twilight.

"Nope." answered Sunset flatly.

"Nope. Nothing yet." answered Spike.

Out of the corner of her eye, Sunset noticed a moving book.

"What's that?" asked Sunset.

A white rabbit jumped from under the book.

"Ahh!" exclaimed Spike.

Spike fell back in his chair unknowingly activating a trap.

"Angel, what are you doing here?" asked Twilight.

"What's that?" asked Sunset concerned.

The shelf nearby moved to reveal a hidden room.

"These surprises are annoying." moaned Sunset.

Twilight saw a book on a pedestal.

"What is it?" asked Sunset.

Twilight walked over to it.

"The Journal of The Two Sisters." answered Twilight excited.

"Must be the princesses diary." mused Sunset.

Sunset looked over at a nearby shelf.

Twilight took the book with her mouth and sat down.

"Maybe this will help." said Twilight.

Twilight was joined by Spike and Angel.

"You read that. I'll keep looking." said Sunset.

Sunset walked over to the bookshelf and began looking at titles.

"There has to be a book on suppressing magic here." muttered Sunset.

While this group settled in, the other four ponies where wandering the castle getting lost and springing the various traps set up. Sunset began picking out books that seemed interesting while Twilight read the journal. Angel stuffed himself with carrots.

"Hey Sunset!" called Twilight.

"What is it?" asked Sunset.

Listen to this entry I found." answered Twilight, more relaxed.

Sunset came over and was relieved by Twilight's demeanor.

"I love to duck behind the paintings. And though the Hall of Hooves still gives her a freight, the trap door slide is Luna's favorite." read Twilight.

"Luna has also betrayed Equestria. Maybe I should visit her." thought Twilight interested.

"Hall of Hooves." repeated Spike distressed.

Twilight flipped the page and continued reading.

"Soon the organ to the outside will be complete and I can hardly wait." read Twilight.

"What's the organ to the outside?" asked Spike.

"I have no idea." answered Twilight, enthusiastic.

"Geez Twi, you're really getting giddy." mused Sunset.

"These are such intimate details about the royal sisters." replied Twilight.

Spike and Sunset suddenly heard a noise.

"Um Twilight, did you hear something?" asked Spike worried.

"This is a dilapidated old castles. Of course you're going to hear noises." answered Twilight.

"I heard a noise and I swear it sounded like a pipe organ." noted Sunset a bit concerned.

Spike nearly fainted hearing that.

"I'm sure we're fine." stated Sunset.

Sunset gulped nervously.

"Am I reassuring Spike or myself?" asked Sunset to herself.

The two ponies went back to reading, but it wasn't long until they heard a noise.

"What in the world was that?" asked Twilight alarmed.

"Sounded like screaming." answered Sunset uneasy.

The two ponies began to leave.

"I'll stay here and make sure the books are safe!" declared Spike frightened.

"Okay. You just stay here alone in the old castle." replied Sunset.

Spike jumped up and gave chase with Angel behind him.

"Wait for me!" exclaimed Spike.

The two followed the noises and noticed the four ponies freaking out in the ruins of the throne room.

"Didn't expect this." noted Sunset.

"I've got to stop this." noted Twilight.

Twilight attempted to cast a spell, but nothing happened.

"I have to get used to not having magic." sighed Twilight Sadly.

Sunset gave her marefriend a sympathetic look then cast a spell freezing everyone.

"What the hay?" asked Applejack confused.

"Must...save Angel." said Fluttershy worried.

The rabbit hopped up revealing his was okay.

"Oh." said Flutterhsy embarrassed.

"Fluttershy, what are you doing here?" asked Rainbow confused.

"She's withe me." answered Rarity, sadly and still under the tapestry.

Sunset, Twilight and Spike walked down the stairs. Sunset freed the others and free Rarity of the tapestry.

"So you four have just spent hours running around and scaring the crap out of each other." mused Sunset.

The schadenfreude Sunset felt was visible.

"I guess." mused Applejack.

"Hey, Sunset could be the Pony of Shadows." accused Rainbow.

"What's the Pony of Shadows?" asked Spike scared.

"An old pony's tale." answered Sunset nonchalant.

The group suddenly heard the pipe organ once more.

"Then what was that?" asked Spike terrified.

"We're going to find out." answered Twilight.

"Probably Pinkie Pie." shrugged Sunset.

The group followed the sound of the organ until they reached its source: a cloaked figure making the noise.

"The Phantom of the Castle." joked Sunset.

"The Pony of Shadows." gasped Twilight softly.

"Seriously, it's probably Pinkie Pie." said Sunset.

Twilight crept up on the figure.

"It's obviously Pinkie." whispered Sunset.

"Now." said Twilight softly.

Twilight snatched the cloak off the figure.

"Hey, did you guys know I could play the organ?" asked Pinkie Pie, "Because I didn't."

"Pinkie!" cried the others.

"Call it!" exclaimed Sunset proudly.

"Pinkie, you're the Pony of Shadows?" asked Rainbow surprised.

"The Pony of what?" asked Pinkie, playing the organ.

"I thought you had to ring the school bell all week." noted Applejack.

"Oh yeah. I only had to ring it for like five minutes. They said that was good enough. Can't image way." explained Pinkie.

"Then I decided to throw a 'Finish ringing the school bell party' but, I didn't have any bluebells and you can't throw a 'Finish ringing the school bell party' with bluebells." continued Pinkie.

"Naturally." replied Sunset flatly.

"So I went to the Everfree Forest to pick some, so I had to wrap myself in the tarp I was going to use to carry the flowers. The I saw Fluttershy and Rarity. But, they went into the castle before I could invite them to my party. Luckily, I followed them inside so I could help you all with your party." concluded Pinkie.

"What party is that?" asked Rarity perplexed.

"Um, the 'Everypony come to the scary old castle and hide from each other while I play the organ party' duh." answered Pinkie.

Pinkie looked over at Twilight.

"Though, I'm surprised you invited her." said Pinkie coldly.

"She didn't come with us." noted Rarity.

"She didn't come with us either." noted Applejack.

"Maybe in the chaos, we forgot about things." proposed Rainbow.

"The scariness caused us to work together." added Fluttershy.

"Hey Sunset, how did you know it was Pinkie?" asked Spike curious.

"She was the only one not here already. It made sense." answered Sunset.

The ponies split off into two groups.

"I'm glad this whole fiasco is over." admitted Twilight.

"So am I." agreed Sunset.

Sunset put the books she picked out in her saddlebag.

"I'm just glad the Pony of Shadows isn't here." sighed Spike relieved.

"Just watch, we'll forget about the Pony of Shadows then he'll return in a long time and we'll have to face him." joked Sunset.

The group all left the Castle of the Two Sisters. Pinkie, Rainbow, Applejack, Rarity and Fluttershy left first as a group. Fluttershy kept a close eye on Angel. As the departed the castle, Angel stuck his tongue out at Spike. The baby dragon would retaliate by flipping off the rabbit. Twilight, Sunset and Spike left second. The former group dispersed upon reaching Ponyville headed to their respected residences. Sunset, Twilight and Spike all returned to Golden Oaks Library.

"Thanks Celestia we're home." sighed Twilight relieved.

"if I never go back to that castle it'll be too soon." said Spike.

"Afraid the Pony of Shadows will get ya?" asked Sunset teasingly.

"No." answered Spike, with fake bravado.

"Good, because he's right behind you." said Sunset.

Spike screamed in fear and jumped around only to find nothing.

"Gotcha ya." giggled Sunset.

"I see you got Celestia's sense of humor." mused Spike unimpressed.

Sunset headed down to the lab and removed her books...about suppressing magic.

"One of these books should the information I need." thought Sunset.
