Right, so first off, you got a couple of options here.

1. Vampires existed as a race before the Thousand-Faced God died. They were a long-lived species that drank blood, sorta existing in the same vibe-check as elves did. They, of course, did not turn others into vampires, because magic (and subsequently curses) were not a thing before the Thousand-Faced died. Theodore's dad did some crazy magic in order to become similar to a vampire, using pre-existing ones as a template. Main deal being that that means that dude was maybe 200 years old, rather than being 'ancient'.

2. Vampires exist as monsters after the Thousand-Faced God died. Same pathway for his dad to follow, though once again, dude ain't all that immortal. Just good at being old.

Anyhow, I'm more or less fine with all that ya got. Probably don't get too accustomed to writing small profiles for all your followers, or it'll be a lotta work in the future. Main thing to note is that Theodore's situation in regards to his capabilities is probably a 'big fish, small pond' sorta deal until he gets to Oratorio, in order to justify his backstory antics. Mostly just to prevent min-maxing shenanigans stemming from one's race. With that in mind, he'll mostly be human, but with an extended lifespan, the ability to digest blood, and a slight increase in physical ability compared to like-sized humans.

Otherwise, iz fine to toss into the tab.
