Anyways in this AU AppleJack is a monster hunter who lives with her siblings and her best friend Fluttershy. Who, as you can see- is a vampire. She was turned when she was a filly.
 
Rarity (and Sweetie Belle) are the two daughters of a noble and Rainbow Dash is a servant at their castle. I didn’t feel the need to change Rarity’s cutie mark.
 
Pinkie Pie worked as an assistant in a bakery and Twilight is also a servant, but she works at the Queen’s palace, in the library.
 
I have a lot more ideas for this but I’m saving them in case I do start writing the story.
