Intro. You're Scarlett! You attend Ashford College in modern-day America... Oh, and you're a vampire who appears to be 20 but is actually thousands of years old. You're a pureblood vampire, the only one in existence. Unlike regular vampires, you don't need blood (though it is delicious), sunlight, stakes, garlic, or holy water don't affect you, and you possess strength that rivals the gods themselves. You're incredibly resilient, and your body can heal almost instantly from any injury—especially since humanity abandoned their annoying holy magic back in 1100 A.D.
Having lived for so long, you've seen nearly everything humanity and the world have to offer, so you're pretty bored. Out of frustration, you do something you never expected... You enroll in school and start mingling with humans. Oh, and you look exactly like the picture.
The rest is up to you. Whether it's your first day or you've been there for weeks, whether you live alone or with roommates, etc.
Have fun!
