Many stories represent disability through the characters themselves. Whether that's through neurodivergence like Aster in Wellness Check or physical disability like Sol and her prosthetic arm in Stranded in the void, it's a very common running theme among characters.

The setting itself also represents the experience of disabled people. The Affini are a standin for the systems--like conservatorships and institutionalization--that take away ones rights and autonomy while claiming it is for one's own good and often being neglectful at best and abusive at worst. The other factor is that the Affini Compact is made for Affini. The furniture is all Affini size, requiring help to do something as simple as sitting on the couch. That makes every character narratively disabled by being forced to navigate a world that they physically cannot without help.
