Cadence......

Nightmare Moon, you won't get away with this...

Celestia, I have felt a disturbance in Cadence's dreams.

The deeper she worms, the more we are all in danger...

An alicorn is laying waste to the Crystal Empire!

Me of course.

Twilight

I stared at the corrupted figure in front of me, now just a remote figure of what had been my sister-in-law. She sneered, "A little too late aren't you Princess Twilight Sparkle."

"Cadence, what happened to you?"

"You pathetic alicorn sisters happened to me!" "Didn't you think, with all of Equestria looking up to you three that the fourth would feel envious?" Cadence asked, a little too loudly. Shining Armor appeared from his chamber and asked woozily, "Honey, what's going on?" Cadence took no notice of him and simply put my BBBFF under a sleep spell. "Now, back to business." She said,looking at me. "Cadence-" "I am not Cadence anymore, I am... BLEEDING HEART!" "I can't have you this way Cadence." I said, looking her full in the eye. If I need to cast a star spell, then so be it." I noticed that Cadence, sorry Bleeding Heart backed up. I guess she'd heard of my famous star spells, which would do anything the user desired. So far, only Celestia, Luna, and I knew how to access these spells, but it was I that had most control over them. I raised my eyes to my stars and my eyes started to glow whitish-silver. I was then surrounded by all the other stars not in the pattern I had created. My horn sparked and a huge ball of magic began to fly towards Cadence. She formed a shield around her but then it broke. My star spell was too strong. It hit her and she fell over. I then commanded the spell to search her and find Nightmare, then cast her out. It found a speck of Nightmare Moon and cast it out. Then, it returned to my horn, and the stars to their rightful places. Bleeding heart became Cadence once again, but then, my star spell backfired and Cadence stood up again, once more Bleeding Heart. All I could think was, 'How did my star spell go wrong?' Bleeding Heart answered, "You sent the stars back up too quickly," she said, growing taller, and now, I have absorbed the power from your star spell. All I could say was, "Oh no..."
