...Well, that depends if 'eaten by an unexplained snake monster' is an explanation or just an elaboration of the extent to which there is no explanation, but yes, that happened.
It didn't actually cross my mind that I might be dead, although I guess it ought to have. I was not conventionally eaten and landed only with the injury I picked up from tripping in the street running from the thing.
Its face was a mirror. I just sort of passed through the mirror, I wasn't chewed or anything.
We have servantmaking, but not magic music or non-servant magical objects. We have a sun instead of shiny trees. Don't have any Valar or anything similar to them. There are various consequences to the not having families thing relative to how you organize yourselves.
Maybe a hundred million - that's inexact but right order of magnitude - and to the extent anyone's typically-appearing for their species sure, I'm average height for a man, paler than most people, etcetera, but not a real outlier.
Nothing's really obvious so far besides servantmaking stuff, but servantmaking stuff is a big deal, we use it for a lot of things. Having a big population's pretty nice, but we do keep dying and have a lot of problems you seem to have just skipped so I'm not sure it's as much of a head start as it sounds like.
It has always - to animals in our world too - there's injuries and a jillion kinds of diseases, both of which we're getting better at managing and treating, and if nothing gets us early then after like ninety or a hundred years we just wear out and our hearts stop.
I think a lot of problem-solving endeavors will need to wait to be planned precisely till we know how accessible the Valar find the world, that's what it's sounded like - somewhere on the spectrum between 'sorry, Kib, welcome to Valinor, at least it's pretty' and 'why yes we can be emergency services for everyone about to die of anything anywhere in your world now that you have alerted us to the problem'.
...In a programming context. Suppose it applies here too. My world might not even be worst off.
I don't, but if you need some blood or something to see what it's made of I don't need it all.
That'd be great. I don't have anything to collect it with, the palace workshops aren't as good as the ones in my home - perhaps you can come over later this week when I've developed a list of all the tests I'd want to runt through, and we can do it all in one go? How about Elenya? That's the day after tomorrow. I also want to learn the language you're speaking but you can teach me while we're running tests.
Day after tomorrow works for me. He has paper on him, because of course he does; he writes this down.
