"Let's split up, girls.", Twilight said, as they gathered in the middle of the giant library. "If anyone finds a possible source of an answer, radio the others.", she explained as she handed out two-way radios.
"Sure thing.", said Rainbow.
"Okay.", said Fluttershy.
"Alright Darling.", said Rarity.
"Okey dokey lokey.", said Pinkie.
"OK, let's do it y'all.", said Applejack.
They began searching in different parts of the library, in old editions, archives, history, mystical tales, tall tales, and many many more. Unfortunately, nopony could find a book regarding the birth of an alicorn. Suddenly, Rainbow called in.
"I think you better come look at this.", she said over the radio.
They came to where she was, but there was just a bookshelf.
"I swear I can feel a draft coming from behind here.", she whispered.
They listened closely, and could hear the air whistling behind the shelf too.
