In the library, Rainbow Dash, Spike and Twilight were looking in a book.
"Hey, you 3!" Pinkie said, "What spell did you choose, Dashie?"
"Oh, hey, I chose a beacon sort spell but I can't get it right!" Rainbow Dash said, turning a page in the book.
"Well, how far have you gotten?" Pinkie said.
"Hardly anywhere," Rainbow said. Her horn lit up. Her horn aura was a magenta color. A small spark flew off her horn. She sighed heavily.
"I can do this!" Rainbow Dash said, lighting her horn up again. This time a small and short beam of light flew up out of her horn and hit the library's ceiling and disappeared.
"I guess that will do!" Rainbow Dash said.
"Good. Now we can look in some books and see how and why the elements changed you into alicorns," Twilight said.
Soon, Twilight and the others were searching in a lot of books to find out why they were alicorns. A couple of minutes went by and no-pony found a book with the answer.
"Wait...I think I found something!" Rainbow Dash said, taking a book from one of the shelves. The book had a picture of a earth pony and next to it was a arrow. The arrow pointed to a alicorn. Twilight carefully levitated the book out of Rainbow Dash's hooves and put it in front of herself, still using her magic to levitate it.
"Hmm..." Twilight said, flipping through the pages using her magic. She finally saw a picture of the Elements of Harmony and out loud read out the section.
"These 6 objects are called the Elements of Harmony. They were once used by Princess Celestia and Luna and now they are used by Princess Twilight: the element of Magic and her 5 friends. Because the Princess' have used the elements before the present users have a chance of being alicorns themselves. That's all it says." Twilight said and then she sighed,"I never wanted to say this but look like we will have to take the train to Canterlot and search the Archives for any more information."
"When are we going?" Spike asked.
Twilight answered, "We'll go tomorrow morning."
