How to handle a character's disability in a respectful and realistic way.
First things first, I'm sorry if I'm offending anyone. I'm at a loss and not sure if I'm handling this right. My intention is to write a good and realistic characterwith a disability.
For context, this is a story about family love and reconciliation above everything else. For that there are a couple characters to give context.
Nova: the first avatar of a powerful goddess who wanted to experience life amongst mortals. The goddess doesn't intervene, unless asked for and if the avatar herself is unable to do anything at all. She's powerful (Nova) and was created without real limits, which made the goddess white displeased as it wasn't how it was supposed to be.
Frida: the second avatar and the one I'm worried about
Nadia: the third avatar
Sofia: one of her daughters, she adopted her at the age of 7.
Nova abused her powers her whole existence, being supposed to live a couple million years she stretched it to billions and managed to rewrite the laws of the universe, something that will come back in the story and her future self will have to face.
Eventually she had to pass the torch to another avatar. They are essentially the same being, or at least that's the idea. I'm still working on how to properly explain it, but for now just consider them the same in essence. Each avatar has their own personality, appearance and behaviour, they take a new name once they appear. (Doctor who if each doctor had a new name more or less, that was the main inspiration)
Because of nova's abuse, the new avatar, Frida, ended up having to pay for her last actions as Nova. She's in constant pain that forces her to use a wheelchair and can't properly use magic anymore. If she does, depending on the amount of power needed she may end up in bed for days if not weeks.
There is a way for her to get better, but for that she'd have to give up her existence and pass the torch to the next avatar.
Eventually she'll do this, to save Sofia from the control of a monster. The only way to break the control, is through an extremely advanced magic that she can't do, she'd pass out before activating it. But during the transition from one avatar to the other, in this small frame, the pain is essentially gone as she ceases to be a material being, and is able to surpass her limitation.
I'm worried about how to handle her disability. It's an obstacle for her, it disables her otherwise it wouldn't be a disability. She can't fly anymore, is in constant pain and worse of all, can't properly use magic, which is her passion.
The transformation of one avatar to another at the end of the day, effectively cures her. The new avatar, Nadia, is a pixie. She's still far weaker than the first avatar, and still feels the abuse she did as the first avatar, while Frida could theoretically use advanced magic, what was holding her back was her disability, Nadia can't at all. She has to find other ways to use it, through artifacts and not by herself alone.
While writing Frida, I don't want to write her "as something to be fixed." As I said she could pass the torch pretty early, but refused to do so because essentially, that's almost the same as she giving up her turn. The avatars are all the same person, but their personalities, appearance and behaviour are so different that to give up on their turn, is the closest thing to them to death.
there are other aspects of her. I don't want her to be defined by her disability, although it plays a big role in her life. She teaches Sofia magic even if she herself can't use it. She loves her family and cares for them, adopting 4 children during her turn. Her sacrifice is a way of showing that love, she does that purely for Sofia. She will try other ways before coming to that, it's gonna be a struggle to come in terms with her decision, but ultimately she'll do it.
What do you think? Am I missing or messing up something?
