Princess Twilight Sparkle struggled, beating her wings in the rain. It wasn't helping that the book in her saddlebag weighed more than all of Equestria itself. After seeing Rainbow Dash soar into the skies above, begining to clear clouds, Twilight stopped for a second, debating wether or not she should talk to her. Though she decided, both her and Rainbow Dash had work to do, also she had better get inside, for it would take even "The Sonic Dash", as she had recently insisted others refer to her, couldn't clear this sky before Twilight could make it home.
Rushing to get out of the rain, Twilight was already preparing the door opening spell, the second her giant castle caught her eye. Almost forgetting to wipe her hooves on the carpet, Twilight hurridly raced up to the library, as she was excited to read this book of Starswirl the bearded spells. Princess Celestia said she sensed an evil arising, that had something to do with one of the spells in this book. She said that even she, herself had never read this book before, as it was written when Starswirl was living amongst the Zebras to learn their ways of magic, and spellcasting. All of the Zebras, with the exception of Zecora spoke a different language, that most ponies couldn't understand. Though, Twilight, in all o her studies had learned how to speak Zebra. Zecora liked Twilight for company for many reasons, one of them being that when she was with her, she could speak her native language. Now of course because Twilight wasn't raised to speak Zebra, she didn't know every single word, and how to pronounce it, so Zecora stuck like she was talking to a small chid.
As she opened lifted the book out of her saddlebag, which she regretted not using magic for, as it was a rather large book, even for Twilight's standards, a scroll fell out of the back. At least Twilight thought it was a scroll, it was actually a page that Starswirl forgot to fit into the binder. Though, it came from the very last page, Twilight knew Starswirls's books didn't always need to be read from front to back, and she decided to read the "scroll", as she referred to it in her mind, first.
It was a spell, Twilight was surprised, in a book about Zebra magic, she would expect it to be mostly potions. "To Conjure the Savior" She translated. Now, anyone who was reading about Twilight reading, perhaps in a story or such, would know from a few minutes earlier in the day, if that happened to be included in the story, that Princess Celestia had said something about an evil arising, but Twilight isn't reading about herself reading, and that had slipped her mind, and she had no idea how conjuring a savior would be relevent to anything in her life at all.
This is when Twilight began to read the spell, trying to forge it into her mind, it was a very complicated spell, and she would have to read it to herself many, many times. She even read it aloud afew times, choosing to sit there and listen to her voice echo through empty halls. She had spent Spike to stay with Rarity for a few days, while she was in Canterlot.
She's not sure, you can never be one hundred percent sure that you can do a spell until you try it, but Twilight beleived she was ready. Twilight's horn began to glow. If you asked her a minute ago, Twilight would have said Rainbow was almost done clearing the clouds, but it seemed the storm was picking up, so much that it knocked open a window, almost breaking Twilight's focus. The aura grew bigger around her horn, as the wind began twirling around the library, knocking down countless books, and getting the floor near the window all wet. Just as Twilight had an impending feeling of something great about to happen, Twilight's horn poofed out, and the storm abruptly stopped.
Twilight wanted so badly to be upset, as she had rather high hopes for this spell, but she was too tired to be upset. She closed the window, put the page back into the book, put the book on the table, and travled off to bed.
