The Origin of the infection: The infection typically stems from a mysterious and sinister entity or a corrupted "Seraphim" flower, which infects ponies upon contact. Also the infection was originally created by Discord as his daughter but she has no body. Discord was young and bored when he made Seraphim. The Symptoms of the infection: Infected ponies undergo physical transformations. They can exhibit symptoms like glowing, divine/cosmic markings, a loss of control over their own magic, and psychological corruption because Seraphim is taking over the infected ponies's body. The three ponies recovering from being infected are Fluttershy and Rarity and Pinkie Pie. Fluttershy was originally the main host of Seraphim which resulted in her now having six legs and being as tall as an adult alicorn. Rarity now has a black coat of fur on her hindquarters and on her back legs and the tip of her horn is now black and her three diamond Cutie Mark is now just a white outline of the three diamonds. Pinkie Pie also has a black coat of fur on her hindquarters and back legs. Seraphim currently is in the artificial body that Twilight Sparkle made for her when she was originally possessing Fluttershy and Rarity and Pinkie Pie. The artificial body is slowly failing. Discord feels guilty because he feels like there's nothing that he can do to help Twilight Sparkle.
