"I'd bet it has never been spoken aloud and that she's done her level best to forget it herself. If her kind magic applies reflexively she won't have been successful but I wouldn't count on that."
"Might need one of the kinds of people who can still interact with fairy orders to make a food claim on her. And if her name's forgotten it would be necessary to continue ordering her via same."
"They age, but when they die they can go on to their afterlife or come back, whichever they like."
"We could bypass the Queen but she's very useful, potentially very obstructive for any in-Fairyland projects if not addressed, and will have concentrated most of the also-useful power and knowledge to be had in Fairyland."
"Well, I suppose we have a while to think about it. But it's a reason to keep an eye out for trustworthy-seeming Men."
Maedhros sends his boyfriend a look that is very hard to read and then sits down. "By 'science' we usually mean the facts about how our world operates and the techniques to figure them out. The techniques should work everywhere, the facts obviously aren't true in Fairyland. One interesting way to teach you science would be to set ourselves the project of understanding which of our inventions will work in Fairyland."
"Both. In theory I would have said before I met you that nonmagical inventions should work on every world that is similar enough to ours to have thinking people of any kind, because the principles that hold it together are the same ones that hold thinking people together. But you are a different kind of thinking person than I imagined, so perhaps I'm wrong about which rules might hold."
"Well, we know Fairyland doesn't obey the thing about no creating new essences, although I guess it could just be technically magic every time something like the sourceless waterfall happens."
"There's fire... Metal's not in common use but it exists and some fairies forge it. I don't think there's coal. I have not dropped things and watched them to check."
Bows and arrows are a thing, although blowdarts are more popular for the obvious applications. Fairyland has sky islands. There's a spell you can do to an intact dewdrop but not to any other form of water. Entire regions spend long periods of time stalled on a single season or time of day; her tree is in a place where it is almost always autumn and usually afternoon. But there are things that seem to her recollection to behave pretty much as Elves would expect things to behave: water usually flows downhill and wind affects the shapes of clouds and fire behaves normally.
