One night a mysterious filly named Lilith, wanders into Ponyville. She is then invited by Twilight to come and stay at her library. After questioning, Twilight comes to realize that Lilith has no home, no parents, and no place to go. With no one to look out for Lilith, Twilight takes her in and decides to take care of her from here on out. Little does Twilight know that Lilith isn't an ordinary filly, and she will soon find out when the residents of Ponyville, including her friends, start disappearing one by one.
