Dimensions

Twilight and her friends were sent home by Midnight after her little incident. They were all given small gemstones attached to a string, each with the colour of their element, as Discord, Starlight and Spike had a greyer coloured one. They asked her why she was sending them away, and why they needed the gems that she gave them. Midnight only said one thing, and then shut the door on them.

"Error."

Why did she say 'error'? Is that a pony? Or is it because of what happened to her? Questions were running through Twilight's mind as she led her friends out of the Everfree and back into Ponyville. Once she had first sight over her sunny town, she remembered that she and her friends had only 5 days until signs of the dimension falling apart will show. Deciding to take action, she quickly turned to her friends, making them know that she was about to say something.

"We need to help." Twilight said with enthusiasm. "We have to."

"And how do you expect us to help?" Spike asked. "All she said to us was 'error', and I'm not even sure what that means!"

"Exactly!" Twilight pointed out. "Maybe that's what she wants us to do! Find out what this 'error' thing is!"

"How do you even know it's a thing, deary?" Rarity uttered. "I mean, Midnight is very robotic-y. Maybe she was saying that because she was... Er... Malfunctioning?"

"I doubt it." Twilight continued. "I bet it's a thing she asked us to find out about!"

"Well..." Starlight coughed. "The least thing we can do is try... Wouldn't hurt, would it?"

"Not at all." Twilight grinned. "Come on, my library must have something! If not, I can send a message to Princess Celestia to ask if she can look in the Canterlot library!"

Everyone nodded in agreement, then ran towards Twilight's castle. When they got into the large palace, they frantically looked for any books regarding the word 'error' in her library. Spike sent a message to Celestia for Twilight to urge her to do the same thing, in which she replied saying that she and Luna would do the best they can.

After a few hours of finding nothing on the word, Discord threw a book down and slumped to the ground.

"This is pointless!" He grunted. "There's nothing here!"

"No!" Twilight yelled. "There has to be something! Anything!"

"Twilight, ah think we've looked enough." Applejack carefully set a book down.

"Hm... What about a book about glitch monsters!" Pinkie Pie blurted out. "Glitch is like an error, and error is like a glitch, so they're basically the same exact thing but with a different name!"

"Pinkie, you're a genius!" Twilight levitated the book Pinkie had out of her hooves. "This could actually be useful!"

Opening the book, pages filled with weird black creatures and their information were revealed. It looked like a journal, as the pages were clearly written on and the pictures were stuck on using masking tape and blue tack. Twilight flipped to the back and front of the book, hoping to get the name of the author. All that was written is 'this book belongs to M.D.L.G'. No one knew who this was, so they presumed that the 'M' stood for 'Midnight'.

"This is probably hers, then..." Fluttershy pointed out.

"I get that." Twilight tapped her chin. "But what are these black creatures? The language written is unrecognisable."

"To you, maybe." Dash smirked. "But if it is Midnight's, we should probably give it to her. She might tell us what it means."

"What if she doesn't?" Starlight suggested.

"I think we should ask Celestia." Twilight closed the book. "Maybe she or Luna would be able to read it."

"If I can't read it, I doubt they would." Discord crossed his arms.

Twilight turned to Spike. "Send this book to Celestia, and send a message asking her if she could translate it."

Spike nodded, and stared writing a letter to send with the book. Twilight looked at the others in concern.

"If one of the monsters in this book is loose in Equestria, then we have to find it."

"But how?" Fluttershy whispered. "We don't even know how to stop it..."

"I still don't see why we can't ask Midnight." Rainbow Dash groaned. "It would be easier!"

"And she might not tell us what it means, Dash." Starlight sighed. "Please, this is the best option right now."

Dash grunted. Twilight paced around the library thinking about what to do with the monsters. Spike wrote his letter, and then sent the book to Celestia and Luna. Hopefully they would know what to do, and they would know what the words mean. So far, this was their only hope.
