The Spirit of Friendship

   A reflection was cast upon the mirror in Canterlot Castle. However, it was not the ordinary guard that stands outside the door to make sure that Sunset Shimmer wasn't coming back. The shadow trembled a bit as she took in her surroundings. It was all very unfamiliar to her. The pony from whom the shadow was cast was also an unfamiliar sight in the castle. Her mane and tail were multicolored and long and flowing, like Celestia's or Luna's. Her coat was not like that of any known pony, however. It was completely pitch black, without any other color, from her horn to her wings to her hind legs, all black.

   As you may now know, this pony was an alicorn. Because her horn began to glow slightly when she appeared, it was starting to look like a lightbulb by now. She attempted to look up at it to snuff it, but realized that she was unaccustomed to this new body after she realized it was a horn and that by trying to go up she had almost flown for the first time. Unsurprisingly, she ended up making a thud as she fell onto her back. Therefore, she realized that she had achieved her goal and her horn was no longer shining due to her surprise, but now she had a lot more to deal with.

   The crystal guard stood in the hallway. He wasn't sure why anyone had to guard the mirror tonight. After all, after Twilight Sparkle came back, she had assured the princesses that no one else would be coming through the portal for the next 30 moons. However, although it had barely been a couple days, Princess Cadence had ordered that the mirror must constantly be guarded. She believed that although the worst of the trouble was already over, the magic portal was very unpredictable, seeing that it had such a strong magical aura.

   Suddenly, he heard a thump! The guard had been so caught up in his own thoughts that he had not been keeping an eye on the room with the mirror. He knew it seemed impossible, but somehow somepony was inside the room with the mirror! The princesses must be alerted right away!
