Backstory is interesting, a fun take on vampirism as contagion. Didn't like that it was an infodump immediately following an interesting hook, though. I feel that works better later in a story, or delivered in bites (hah).

Used the random tables to generate my PC's traits. I'm liking what I got; it matches how I envisioned him naman.

TRAIT 1: Mildly immunocompromised, currently in remission, set to return in 2 months since game start. Works for me, especially lore-wise, as part of his randomly-generated lore is his experiencing adverse (albeit supernatural) effects from taking a certain medicine — that being losing his romantic desires for his partner. (I've interpreted this as him not fully accepting his aromanticism and being too stubborn to admit it, so he uses medication as a scapegoat).

TRAIT 2: Moderate haphephobia (triggered by touch), lasts 30 minutes after stimulus is removed.

Interesting combo <2 Can definitely work with this!

"Fifteen to twenty percent of people worldwide in real life have some form of disability. In a world with less medical, therapeutic, and nutritional science but additional magic threats, the rate of disability is likely higher."

Makes a lot of sense. I didn't know that was the statistic for IRL disability, though! Did a quick search and WHO's website states the percentage is 16%, though I imagine the reality is actually much higher given the number of undiagnosed people.

"With ability checks, you make something happen. With saving throws, something is happening to you. We hope this will help people recognize that many actions may seem like conscious decisions to those who do not experience those traits, but are in fact involuntary or nearly impossible to avoid."

Great logic to fall back on when it comes to deciding on rolls for disabled characters. I had a BPD character in a game once who'd roll constant Wisdom saves against his own knee-jerk anger; I felt this more accurately reflected the struggle of that disorder with respect to the one suffering it rather than just putting him out there without explanation, at risk of those unfamiliar interpreting his behavior at face value, as entitled or cruel by conscious choice.
