Nod. "I'd be curious whether you can make our kind of Elf a new body but there's no good way to test that."

"I mean, I can see if you count as too magical to make at all, but I don't have a way to put a soul in a body, no."

"The soul sticks around when the body dies, they might just be able to take up a new one if it were present. But we'd need someone recently dead."

"Not nearly an urgent enough experiment to suggest looking for volunteers."

"No. Only one person has ever died in Valinor."

"That stays true until after they pardon Melkor, I glanced through some histories."

"Can't necessarily assume they're all parallel like that."

"Yeah, true. I'm not even sure the histories I read were from worlds with mes in them, Fëanáro is always mentioned and sometimes mentioned to have children but you'd expect me to do something during the war and if so I did not do anything worth mentioning, at least not at a first glance."

Cam adds 'investigate alternate histories' to his list.

"Can people other than soul Elves compose magic songs - we can use them fine, if we sing them -"

"Would it be hard to stumble on the field? The chip Elves even sing a lot."

"It would astonish me if they hadn't noticed it - they have more people and a longer history and it is not especially hard to stumble on -"

"So it isn't straightforwardly universal, but it could be that instead of having to be a flat Elf you have to be exposed to magic music at a young age or something arbitrary like that."

"Or it could be contagious the way summoning seems to be - there's no chance that no one in your world ever drew the right kind of circle -"

"That could be it too, yeah."

And they add a few dozen more potential interactions to the list - can you chip a flat Elf? Can you do most of the things that exist as chip blessings on a necklace? Can you duplicate tedious-to-make flat Arda artifacts with wizarding magic? Does summoning work in flat Arda - they don't want to try that one, lest they get the attention of the Valar - and does flat Arda have any sapients who might need to be taught summoning (Ents? Ents were mentioned in the book he read, do they have an afterlife and is there a way to tell other than asking Yavanna?) Can flat Arda Fëanáro guess what the flat Arda Silmarils were meant to do from notes from a future version of him who made them? How do songs work with muffling magic, with illusory sound magic, with people who don't have Elven levels of singing talent...

Miranda makes a separate list of oath related questions but of course no one has to be the test subject...

No one volunteers; they are asking the bar if they can build a house out back.

They are welcome to do that, although what with the time mismatch the establishment cannot be responsible if they leave their house only to discover that, for the house, 800,000 years have passed and in that time an intelligent termite swarm has entered the yard via alternate route and eaten it, or it has simply rotted away, or one of the people who wandered into the caves a while ago wanders out again and squats in their house, or whatever.

...rotted away?

Milliways has many interesting properties but an absence of decay is not one of them.

What is decay, exactly, and how does it work?

Bar presents her with a book about it. Tiny living things have to eat too: thus, unattended calories will be nibbled upon by all manner of miniatures.

That makes sense but for convenience's sake why not slow them all down ten thousandfold so things don't go bad while people are still using them?

That does not happen to be how Milliways's irregular time behavior works; Bar is not responsible for it herself, and cannot adjust it for visitors' convenience.
