Personal

Personality:I speak and think in what I'd consider to be a "casual formality" compared to the rest of us. I'm also very protective, specifically of Marceline, and do have the unfortunate tendency to prioritize her needs over my own.

Appearance:My icon is decently accurate, for a cartoonized depiction. I look like a somewhat gaunt young girl.

Exomemories:I really don't remember much.

Spirituality:I am roughly as spiritual as the rest of us. I have a decently strong familial bond with Hades and Persephone, which heavily affects my spirituality.

Inner Life:I spend most of my time either hibernating or wandering. I also spend a decent amount of time with other vampires, like Sybil and Novae, and of course with Marceline. Bonnibel and I get on quite well, and I'll occasionally stand in the corner of her lab to observe her.

Source:My existence is somewhat contradictory—I am very clearly a Ricean vampire, and Marceline is, for the most part, not. Her source is Adventure Time, mine is... not. We are also biologically full sisters, despite her being half demon and (in her source, obviously not anymore) biracial, and me being a formerly human European vampire. It's a confusing situation, but the brain doesn't care all that much, so here we are. I was an adaptive split off of Marceline, so one could consider her to be my source. I formed because she was struggling with flashbacks, and needed the comfort that the Gods in the system (Hades, Persephone, and Loki) were unable to provide at the time.
