Starlight Glimmer (Equality is Magic AU)  
Equality is Magic a Starlight Glimmer AU  
In this AU starlight got the magic element of harmony and twilight stayed in canterlot. Starlight took all of pony vills cutie marks and is expanding out. Out of the mane six she only kept Rarity, Rainbowdash, and AppleJack keep their cutie marks since she found them useful. Starlight has a spell on the carousel boutique making it so that rarity can’t leave it. She uses Rainbows loyalty against her by keeping scootaloo captive and forcing rainbow to act as a guard. She has rainbow guard the cutie mark vault which has expanded. Applejack has an enchanted saddle that gets tighter every time she stopes work the rest the apple family has saddles that tighten too. AJ learnt this the hard way when Granny Smith died. Pinkie has became depressed, fluttershy went missing they’re rumors that she died and her soul now stalked the everfree Forrest,and twilight is still studying in her old home oblivious to all of this happening as there is a spell making it so ponies outside of ponyvil just see it as normal before starlight made anyone equal. The ponies from equal town now live in ponyvil. Double Dimond, Party Favor, Sugar Belle, and Night glider are called the Four Horses of the Apocalypse by the ponyvil ponies. Starlight ordered them to go around looking for ponies who got their cutie marks and notify starlight so she can make the equal. To show their loyalty when starlight gave the Four Horses of the Apocalypse their cutie marks back they carved them out with a knife. The cutie mark crusaders no longer want to get their cutie marks out of fear and even if she wanted apple bloom can’t leave the barn anyway so what’s the point. No one (except for starlight) is quite sure what happened to princess Luna she just disappeared. Starlight wears Lunas cutie mark as a sign that she should be feared.
