Prelude: Fixing the Spell/Meeting With Celestia

After a chaotic day of restoring cutie marks after casting Starswirl's spell, it finally came to Twilight. The words of the spell she was trying to fix came to her mind. After her and her friends returned to the library, she grabbed Starswirl's book and wrote the proper spell inside of it.

From all of us together, together we're friends. With the marks of our destinies made one, there is magic without end!

As soon as she finished writing the spell, the Elements of Harmony began to behave in a way that none of the six had seen before. They began to glow and suddenly Twilight found herself encircled in light. At first she felt panicky because she had no idea what was happening but soon would develop a smile as she had a feeling that she may be fulfilling the destiny that Celestia had had for her ever since she took her in as her protege.

When the light subsided Twilight found herself in a dark realm that was filled with stars. She had no clue where she was and asked, "Hello? Where am I? What is this place?"

Twilight saw a figure in the distance that she did not initially recognize that was approaching her. The figure said, "Congratulations, Twilight. I knew you could do it."

After hearing the voice she immediately knew who it was, Princess Celestia. She ran to her and asked, "Princess....I don't understand. What did I do?"

Celestia gave her a smile and replied, "You did something today that's never been done before. Something even a great unicorn like Star Swirl the Bearded was not able to do, because he did not understand friendship like you do. The lessons you've learned here in Ponyville have taught you well. You have proven that you're almost ready, Twilight."

Twilight gave her a nervous look and asked, "Almost ready? Almost ready for what?"

Celestia's horn lit up and a door with light shining in appeared in the distance. Celestia pointed her hoof towards it and replied, "Follow me and you shall find out."

Twilight gave her a nervous smile and followed her. She wasn't sure what it was but given that Celestia had said she was nearly ready, she figured that it couldn't be anything bad.
