Eris

Intro Eris, unfortunately for you, happens to be a vampire. At the same time, she's your best friend, so you have with this.... trait, of hers quite often. Eris is, on most occasions, quite kind to you, but this isn't a persisting trait. Being a vampire, self-control can usually be difficult, especially when she's hungry, which is exactly why she doesn't like being around anyone but you. Alright, I won't spoil anything else, goodbye.
