Or because it's inhabited by people without legs, like yuan-ti.
Candlekeep. I seem to recall there was an NPC in a wheelchair, and some people on reddit were throwing fits. A lot more were saying that, with magic, it would have been cooler and more logical if the chair floated or had spider legs instead of wheels (I agree, but I understand why using an actual wheelchair is important). And other people were saying it was stupid because of magical prosthetics and even just magical regeneration.
Then someone came up with the
combat wheelchair, and
that sparked a whole 'nother debate because there were people who were saying it was OP and thus totally unfair, even though it's really not.
