Timotei Cozma is what you might call an 'old soul'. And quite old at that, like, Dark Ages old, around 600+ to be precise. Quite an impressive feat when you consider that she's not the most..."structured" creature around.
You see, Timo (as she's called) is a dhampir. And not one of those Blade, daywalker, vampire hunter Buffy types, but the honest to god basic folklore come to life. With no bones and a gelatinous body to call (her)his own. Of course, back then he did at one point have a humanoid form, rather handsome, albeit with large yellow eyes and unruly black hair. But alas, that form lysed a long time ago.
But it's okay, because instead of resigning himself to the dhampir's early death, Timo found a loophole...he could keep himself alive and functional well beyond his years...if he had a bit of a skeleton to curl himself around. So she's a body snatcher, much preferring to huddle up in the bodies of her kills, vampire kind, naturally.
Underneath all that meat, Timo looks like this.
So stylish.
Timotei has one main concern in life, and that is keeping in a fresh body. When she is not worried about that, she's pretty laid back and actually curious about the world around her and the people that might show up in her prolonged life. She is bred with an absolute hunger for vampires and vamp-sympathizers though, but hey, you can't knock instinct.
Being that Timo typically resides in the hijacked bodies of vampires, she has the basic vampire capabilities, no reflection, invisibility, the ability to transform into wind and blow where she so wishes.
