Rarity watched Twilight as she was mixing something in a cauldron. She was very curious, yet Twilight never gave any hints as to what she was mixing. After a few more moments, the alicorn stopped stirring and was now pouring the teal mixture into a clear bottle.
"Drink it!" Twilight shouted enthusiastically, levitating the bottle over to Rarity using her magic.
Rarity was hesitant at first, but slowly took a sip of the teal liquid. The moment she took her lips off of the bottle, strange things began to happen. The first thing that the unicorn noticed was that her entire body felt like it was on fire, as if the heat had been turned up super high. Her mouth was in intense pain, as if her teeth were growing. Twilight watched this scene happened, and noticed Rarity's eyes had become a neon red, they were basically glowing. She screamed when the unicorn had grown a pair of bat wings straight through her back.
"What's happening, darling!?" Rarity questioned, she was in a frenzy.
Twilight looked at Rarity straight in the eyes. "At least we know what the potion does."
-------------
"WHAT?" Pinkie screamed.
Twilight sighed. "A vampire. My potion turns ponies into vampires apparently."
Fluttershy's eyes widened as her mind flashed back to when she had become a vampire fruit bat pony. She felt sympathy for Rarity. "Oh, my.."
Rarity was still at the castle, hiding away. There was no way in hell that she could show her face in town right now. Her stomach growled, even though an hour beforehand she had eaten a big breakfast. Curiosity overtook her when she spotted a book on the table titled Vampirism. She levitated the book over to her with her now red magic glow and turned to the first page.
"Fledgling vampires only have a week to feast on blood once they have been transformed, or else death will overtake them and they will die."
Rarity gasped. "I have to tell Twilight!"
