I am perfectly happy with my physical form. How can I best avoid perturbing it, and if it does wind up perturbed can I put it back with sorcery without adverse effect?
"You must change something or the new name will not take. I can direct the change towards your habits and preferences instead, but this is not certain to work. I do not know what sorcery is capable of, but if your form changes it will be your natural form. Any magic to change it back must be permanent."
Sorcery can do permanent. I'd rather have to cut my hair and turn my wings green again or something than adjust to new habits and preferences. I have a tree which is magically connected to me. Is there a risk that it will no longer be mine in the right way when I am renamed?
To the extent that a fairy kind is like a species, yes. I have a tree because of my kind.
All right. What advice do you have on name structure? Can I include variant "pronunciations" so that I may render different valid forms of it including, say, either explosions or dramatic temperature changes, as I please?
Other than that, it's time for another long list of examples.
And then go study up on de-aging mortals.
Nick tries to learn sorcery. He gets very good with fairy lights and fire in under a week, and then asks for suggestions and advice once in a while. Always with a tentative "If you don't mind."
Promise (who still hasn't fixed her ears except while alone inside her tree, and still finds it weird to speak aloud while deaf and unable to moderate her volume) suggests learning to help plants along, or purify water, or make candied dewdrops.
And finishes up her name, which is a masterpiece of escape routes and offense and defense and the occasional syllable.
You might be guessing that I take promises to others very seriously because of my nickname, but that's actually not what it's about. Barring discovering something unexpectedly horrible about you between now and then, though, I promise.
And then, having set up appropriate target dummies ahead of time, she "says" her new one, complete with the flying and the exploding and the hand gestures and the fairylights.
She doesn't fix her ears. But she thanks the apellodyne in fairy lights.
Nick is grinning at her. I'm glad I could pay back my debt of freedom at last. He holds out a little silver coin. Where I grew up, a gift of silver is the traditional way of congratulating someone for a significant achievement, or to welcome someone returning home. This isn't quite the same, but please take it.
