Kib can't so much flee. He can shriek - he can lurch in the direction of the nearest house and try the door - it's locked. He can amble briskly...
He can break into a run when the snake gains on him and fall flat on his face.
And he can get eaten up.
And it's too bright too bright too bright and he flings his arm over his eyes.
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.
What? I like him. He's going to attack the entire problem of death because he heard some people he's never met before are dying. That's awesome.
Yes, he asked me for a three-sentence version of everything more interesting about you than the language - which he finds very interesting, he'd probably have kept you up all night if it hadn't turned out you come from a planet of dying people - which is a very efficient way to get to the heart of matters. But 'nice' doesn't always leap to mind.
