This universe has a civilization of humans! And some other things. It's not crowded in the way Edda is but it's not just the one planet either. The humans might be easiest to start with. They're on that planet over there, it's not Earth but it has very Earthlike conditions and bronze-age humans living in cities and villages dotted across two large continents. Depending on how thoroughly any prospective visitors look they might find other things before visiting.
"Oh, well, I joined up when - for a while after Vanda Nossëo found my planet I didn't have a job, kind of a lot of us didn't - my subgroup of my species. We took a while to get used to the multiverse, enjoy having Vanda Nossëo basic income, lots of us immediately started having a ton of kids, took up a lot of hobbies we hadn't been able to try before. And that was fun, for a while, but then I wanted to be doing something. If I were married it'd probably be the having a ton of kids thing, my species loves kids, but I'm not, so I wound up in an employment office and it funneled me this way and I passed a screen for the extra fancy spells. Eventually I'll meet someone and settle down. Maybe still do a turn as an ambassador now and then while the kids are at band camp or something."
"There's some internal difference too, and stuff that you can only see over time - I can go from as pale as Tarwë to darker than Cassiel in the space of a few days if I get enough sun, and then back again if I stay inside. But mostly you can think of Amentans as humans who really really like babies."
