"Ugh." Lyra groaned, opening her eyes to the familiar library. "My head hurts." She reached up to rub her head and caught a glimpse of her hoof. Only, it wasn't a hoof. It was a hand, five fingers and all. "Mother of Celestia." Lyra whispered. "Can it be?" Lyra sat up and inspected her body. Sure enough, she was a human. "This - this is amazing." She looked to her right to find Bon-Bon laying there unconscious. She was human, as well. Lyra ran over and shook her friend. "Hey, Bon-Bon. Bonnie, hey. Hey, Bons, wake up." She said.

"What?" Bon-Bon groaned, opening her eyes, which widened upon seeing her friend. "Oh, my gosh, are you really a..." Her voice trailed off.

"Yep. And you are too." Lyra said. Bon-Bon looked down to see her naked body. Her face turned a bright red and she curled up into a ball. "Oh, come on, BB. It's not like we didn't walk around naked when we were ponies."

"I know, but, we didn't have - these." Bon-Bon said.

"It doesn't matter." Lyra said, standing up. "If you're human, too, that means that Twilight must be, as well. But she's not in this room. Come on, we have to go find her!" The pair ran through the house, having to duck through the now small doorways, eventually finding Twilight in he room. She was indeed human, wrapped up in her blanket and staring out of the window. "Hey, Twilight?"

"Look." Twilight shakily said.

"I'm sorry, I should've told you what the spell did. I had no idea it was unstable, I didn't mean for it to -" Lyra said.

"Look." Twilight repeated.

"What is it?" Lyra asked. She walked over tot he window and looked out. Everypony in Ponyville was human. The pegasi still had their wings, but, like Lyra and Twilight, none of the unicorns had horns anymore. "Oh, no. Oh, no, oh no, oh no, oh no." Lyra said, backing away. "I caused this, didn't I?"

"Yes." Twilight said. "You did."

"I'm sorry." Lyra said, shaking.

"Well, on the bright side, people can study humans now." Bon-Bon said, trying to lighten the mood.

"Twilight, can you keep this a secret?" Lyra pleaded. "I don't want anypony - or, um, anybody to know that I caused this. Please don't tell."

"I won't." Twilight said.

"Thanks." Lyra said, hugging Twilight.

"But now there's the problem of magic." Twilight said. "Can we still use it?"

"I don't know." Lyra replied. "Try it out."

"Okay, um... Here goes." Twilight said. She focused on a book, and it levitated with ease. Her hands glowed the same iridescent lavender her horn did.

"Okay, we use hands for magic." Lyra said. "Got it."

"Now can we please go get some clothes?" Bon-Bon asked.

A Royal Decision

"What's that?" Celestia asked herself, her eyes darting out of the window. "There's been a very strong spell cast." Her eyes eventually became affixed on the town of Ponyville,which was shining an iridescent blue. "What is going on over there?" Celestia cast a simple magnification spell to zoom in on the source of the magic. She zoomed in just in time to see Lyra's horn shatter. Celestia immediately knew what the spell was. "Oh, no." She said. ""There's nothing I can do for her now."

The spell Lyra had found had been developed by Starswirl the Bearded ages before. However, after having a test subject use the spell inside of a magical barrier, he discovered the instability of the spell and had all records of it destroyed. However, one record of it must have survived, and been discovered by an unlucky unicorn.

"This is not good." Celestia said. "It can't spread. I won't allow it." Celestia's horn lit up as magic coursed through it, sending a magical field across Equestria,creating a barrier around Ponyville. Upon connecting with the barrier, the power of the spell clashed with that of Celestia's, but the princess' power proved stronger, destroying the other spell. "Well, that's that." Celestia sighed. "I have no choice but to leave the barrier up. Should the spell somehow re-create itself, as it did with Starswirl, then it would turn all of Equestria into humans."

Princess Celestia summoned a guard. "Have somepony travel down to Ponyville and hold up a piece of paper, use sign language, or something along those lines to convey this message to the town's residents: Due to the recent transformation of Ponyville residents, no one is allowed to leave. Ponyville is officially a quarantine zone." Celestia said. Once the guard had left, a single tear rolled down the princess' face and she whispered, "I'm sorry, Twilight."
