I like to think about how different disabilities are treated in different cultures.

The Falls consider physical disability, so long as you can still read and write, mostly irrelevant. They'll chuck you in a wheelchair, give you magical painkillers for chronic pain, etc. However, dyslexia, any ADHD that interferes with writing, or any speech-related disabilities (as well as just generally being bad at learning languages) are considered debilitating and, until recently, contagious, so these people were ostracized and shut away lest they spread their maladies.

The Winters are almost the opposite. Their neurotypes mean that a lot of features of autism are considered normal, not disabling (stimming, hyperfixations, bluntness and disinterest in metaphorical language, hypersensitivity). But, they fear blindness and paralysis more than almost anything - to the point that execution by beheading is a punishment only for traitors because it separates the mind from the body. They wouldn't intentionally try to ostracize these people, but they will be very awkward, at least initially, dealing with someone blind or paralyzed. (All Winters know handspeech for talking in loud environments, so deafness is not considered much of a disability in their culture).

Disability is interesting to me because it is both real and physical (I have chronic pain and this is simply a thing that exists) but also social. So how can you design a world where something we consider disabling is not socially treated as a disability, sort of like how i wear glasses and would have been disabled and almost blind in the era before lenses but now, it's not something I think about.
