When thinking of things that can be easily misplaced, ‘keys’ are the first thing that comes to Twilight’s mind. Due to her hardwired, overly-organized nature, she would often find her keys where she’d expect them. Should they not be there, on third loop of the key holder directly to the right of her bedroom door, she would safely assume Spike had misplaced them. She very rarely misplaces things like her keys on her own accord. 

The master key to the School of Friendship wasn’t something that could be easily lost anyhow. It was rather large, almost as big as Ponyville’s key to the city. Twilight appeared before the doors of her School of Friendship, ready and eager to feed the growing minds of her class everything she had learned about the matter. With a twist of the key, the doors were opened. Behind them, sat Starlight Glimmer at a wooden table with a tea set,

And literally nothing else. 

Aside from the door and the frame it was bolted in, Twilight’s entire school was [i]misplaced.[/i]

“Have a seat.” Starlight spoke in a rigid tone that easily indicated just what type of headache this conversation would produce. Headmare Twilight Sparkle, God-princess of friendship, narrowed her eyes, almost as if to increase the pressure of her glare stream. 

“Wait outside, Spike.” Twilight ordered coldly. She walked through the door and shut it behind her, leaving a very confused young dragon on the other side of the useless frame. If he could just walk around it, was he outside enough? He shuffled in place before ultimately taking off. 

Starlight lit the chair across from her with magic, prepared to telekinetically pull it out for her mentor, only to have the much stronger alicorn magic yank it away and position it. Twilight carefully sat in the chair which was clearly indoor furniture that was out of place in the pit where the school should be. 

“I’m sure you have multiple questions…” Starlight started as she levitated the kettle. 

Twilight cut her off. “I only have [i]one[/i] question.” Her voice was frighteningly firm. Starlight had trouble pouring tea into in to the cups and almost made a bit of a mess. Another mess, that is. 

“You want to know where the school is?” 

“No. I want to know how this happened.” 

This was a much more difficult question for Starlight to answer. Twilight could tell, based on her subtle change in expression. She knew that look. She had been in similar situations in her youth under Celestia’s tutelage. 

“How? Okay, well uh, let’s see…” Starlight fished for an explanation in her mind, mostly succeeding in wasting time. Twilight poured herself another cup of tea, almost as if to illustrate how long she’d be willing to wait. The sound of the oddly muffled waterfalls seemed to grow louder in the silence. “So, you know how Trixie’s been learning magic?” The tea cup Twilight brought to her lips suddenly floated back down to the table at the sound of Trixie’s name. “I decided that, you know, after school, I could tutor magic for her and any other creature who was interested. So, when you went home yesterday, Trixie and a few other unicorns came in and we tried some simple stuff... at first.”

Twilight leaned over the table slightly, “Why was this something you couldn’t tell me? I’d have allowed it if you had just asked me. In fact, there was a meeting yesterday about after school activities! That you attended!”

“Yeah, well, the idea kinda came to me post hoc, and I kinda figured the magic classes would be more of uh, you know, an 'adult ed' type thing, so it was pretty late.”

Silence. 

Twilight spoke first after looking down where the halls used to be and let a sigh go, “It could have gone b-”

“It coulda been worse! I mean, Trixie didn’t do it this time.”

“This time?!”

The sweat drops won’t stop falling. Starlight tried to pour another cup of tea, only for nothing to come out. Twilight set the kettle down forcefully with a hoof. 

“Well, Starlight?” She stood up, “Where did you and your class teleport my school?” 

Starlight gulped, “Nowhere.”

“Wha…” Then it clicked, “Oh… [i]ohhhh…[/i]” She looked around, sighed again, and buried her face in her hoof. “Is it indespectia or limpidalus?”

Starlight aggressively sucked air through her molars in discomfort. 

“Starlight!”

“I’ll go get the paint buckets.”
