Hello and welcome! Darth Nox here is from that one famous sci-fi soap opera, you know, the one where no one ever gets any therapy and usually ends up becoming a problem for the rest of the galaxy as a result.

He's incredibly Tired and mostly keeps to himself, but he does have a habit of roaming around to see what he can learn about his new surroundings, usually at night. And he'd definitely recognize a vampire, even if he'd have absolutely no idea what the hell a vampire even is. But when you navigate the world around you with a constant connection to the Force (and by extension, just passively sensing life in general), I imagine any kind of undead would stick out like a sore thumb.

Fortunately, his first instinct would be to find out more rather than go all Van Helsing on anyone. Because he's a nerd, and also because as a general rule he doesn't care what anyone gets up to so long as they don't become A Problem. So he might make for a good unaligned (and morally gray) contact for her, especially if you plan on her being anywhere around Sunset Falls!

He might also be down for helping with the blood problem, though it'd definitely be contingent on whether or not they get along / whether he has any reason to believe she'd become a threat if she drank it.
