Okay, I missed that.
Mythic origins create a lot of issues here though with that terminology. I would probably want to go with peoples or species, but the problem species presents for fantasy gaming is it sounds anachronistic (I think most people, even many of the folks who super), it actually has worse real world implications than race did in D&D (because now instead of all humans being one race, they are one species, which does open up the possibility of them having subspecies: which would be classic racism)*, it isn't accurate to real world uses because humans and demihumans can often have offspring (pretty sure different species can't interbreeding real life). But race can work here too. Especially if you are saying all humans are one race. The human race is a concept in real life that people invoke (rather than different human racial groups)
Again though, pretty much any term you can think of, species, peoples, lineage, ancestry, race, etc has been used to advance racism in the past, so there isn't likely to be one that is entirely free of the concerns people have.
*Obviously this is a pretty remote concern as it requires designers actually doing that but it is at least a logical inference some gamers could make
