Word for non-monstrous peoples?

Hey folks! I'm writing up a description of a town, and in covering the town's history, I'd like to use the phrase "frequent attacks by both monstrous and _______ invaders", with the second word meaning non-monstrous. Is there an official or generally accepted lore word for this? "Sentient" or "sapient" really don't work because there are definitely sentient/sapient monsters—illithids, beholders, dragons, etc.—and all a cursory Google search spits out is "character species", which is a little too rulesy. I'd like something a bit more prosaic if possible; I could rearrange it into "frequent attacks by invaders both monstrous and otherwise", but I'd prefer a descriptive word to replace "others"/"otherwise" if possible. I'd reach out to a writing forum, but I thought I'd try here in case there's something D&D-specific that applies. Any ideas/suggestions would be greatly appreciated!

"Humanoid" might be the closest thing to what you're looking for, though that has a specific meaning within D&D rules as a Creature Type that doesn't always match what people think of as its general meaning.

What, exactly, are you using as a difference between "monstrous" and not? Perhaps change monstrous to be something you can more easily write an antonym for?

I use "mortal" in my settings to collectively refer to all the various humanoid species such as elves, dwarves, humans etc. If however it's being used in contrast with the unusual, I'll often use "mundane". So in your example I might say "frequent attacks by both monstrous and mundane invaders". Or for slightly more dramatic grammar "Frequent attacks by invaders both monstrous and mundane". The later phrasing also works with "mortal"—"Frequent attacks by invaders both monstrous and mortal"

Invert the order

"frequent attacks by peoples and monstrous invaders"

All the thinking/playable species are peoples in my world. I think that works for modern D&D quite well. 

How about mundane. Where monstrous is the more fantastical D&D stuff, it could be describing bandits and wolves such. Also a nice little alliteration.

Specifically what invaders are we talking about here? What are you putting in the "monstrous" and "non-monstrous" categories?
