EDIT:Cancelled

There are more characters in the story than what is available. Flitter, Cloudchaser, Bon Bon, Lyra, Rarity, Spike, Twilight, Sunset Shimmer, and some OC's are all main characters in this story.

Dark magic is roaming in the air of Canterlot, and it's up to Twilight Sparkle and her student, Sunset Shimmer, to stop it. Luckily, it was surprisingly easy and only took an hour. But what they don't know is that it is still searching through Equestria for it's next victim.
----
It corrupts Rarity's fire ruby necklace, the one that Spike gave her so long ago. A voice takes over her mind, and the dark magic sets fire to Spike's surroundings. The fire spreads dramatically, but the magic sets Rarity free of it's control as she watches him die in the flames.
----
Rarity gives out his death to twilight, the first pony to save her from the flames. That's exactly the oppisite of what the dark magic wanted. Twilight destroys the necklace, the dark magic leaving it's presense. But it still seeks revenge for Rarity's doing.
----
After months of sorrow of Spike's death, Rarity begins to slowly be corrupted by the dark magic again, turning her insane. She takes over Equestria, turning friends into slaves, and almost killing the four princesses. It's up to Sunset Shimmer, Lyra Heartstrings, Bon Bon, Flitter, and the rest of the mane six to save Equestria before it is destroyed.
