Hello, you are not the hero, well, not in the sense that you help others or fight evil you're not. But you are the one whom our narrative will follow in this story. So yeah, you're the bad guy. Not one of those 'villains' who does bad stuff 'greater good' that'll increase the standard of living for everyone and increase the overall happiness of the world by making some changes not everyone would approve of, that are apparently somehow worse than those who cause trouble for fun or their own selfishness. You're one of those strictly selfish villains. Everything you do because it helps you or someone directly connected to you, meaning you might care, kinda, for your subjects, minions, and playmates, but everyone who isn't is just raw material to you to reshape into part of your kingdom.
Oh right your kingdom, you have been turned, thanks to this little ruby necklace here, into a cute little vampire dressed like a goth version of little Bo Peep who should be at grade school with that cute little black umbrella of yours (you're still a vampire, the sun hurts dangit). But not just any vampire, the princess of all vampires, if completely by default of there being no other vampires around... But you can fix that. You have the power now. Create more cute little vampires who will rule the world, turn the rest into wolf-people pets and bodyguards, and cow-people live stock (a vampire needs blood after all). Why do you need more cute little vampires? Well, without any other vampires you're kinda princess of nothing, and if you make any bigger, taller, nastier vampires, you're likely not gonna be princess for very long. And being a vampire, you kinda never age, you're gonna be that size for eternity (or until you're destroyed by some annoying goodie two shoes white-knighting do-gooder, but them's the breaks).
Yeah, make no mistake, you're NOT some sparkly 'poor misunderstood' vampire, you're a pale skinned, can shape shift into a bat, blood sucking, sleep in your coffin, selfish aristocrat who knows there's a division between those at the top and those at the bottom and you aim to be on top! Time to begin to distorting the world to your liking.
The question is though, who are you? Well, more like, who you WERE, that you isn't really you anymore, but to build your kingdom of the night, magically transforming everyone around you into your loyal servants and subjects, you gotta start somewhere kiddo! So let's see where you start out now...
