wheelchairs
whatever, man
The funniest thing about D&D wheelchair discourse is that they have existed since the 6th century BCE, and would be present for most settings that D&D journeys are based on. Mostly for old, high ranking and rich people, but not a mystery.
Alright you might not see them much in fieldwork, exploring tombs and evil castles, but then you didn't get many bookish alchemists or ritual priests delving like that either.
But that's not what is interesting to me. What's interesting is the part of the discourse that says "why wouldn't they heal any disabling injury?"
I am always fascinating by healing magic, and the way it works in various settings. (In my arguably most successful work, the villain is the world's only magical healer.)
Oh, biological manipulation magic, growing wings or an extra arm or raising an army of clones from a drop of blood, whatever that's no different from any other power fantasy.
But specifically healing is always about "returning to a state of wholeness." Drink a potion and your wounds all heal, that missing toe comes back, your concussion stops ringing - but that's it. You don't age back to 25, or get your virginity back, or forget the horrors of war, or grow some extra muscles you didn't have before but would be useful.
For "healing" to work as simply as it does in most magical settings, requires there to be an ideal self it can always refer to.
And so the wheelchair-ists implicitly claim that the self without the ability to walk, is the real self they heal to. Not to heap scorn on them, as everyone has pointed out, Professor X lives in a universe with seven thousand different types of healing and robotics, but uses a wheelchair iconicly.
(Fic idea, person who uses a healing potion and heals to a different gender. A whole society dealing with this.)
That last fic idea is actually a thing that happens to a side character in Stormlight Archives.
The world premise is that healing restores you, roughly, to your self-conception. So for instance there's a character with a prominent scar, and healing doesn't remove the scar because it's a huge part of his identity. And then at some point he goes through a character arc that leads him to stop thinking of that scar as an important part of his identity, and when the character growth concludes then the scar goes away.
But there's a side character who is a trans man, and when he eventually gets access to a form of healing, it changes his body to match. (If you read the books and didn't notice this—it did happen, but you have to be paying a lot of attention to catch it. It's a side-side character and you need to compare two passages that are in separate books to catch it.)
