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.
"It does seem like that might be difficult for your law enforcement infrastructure. We're happy to help as long as we're here with fires and any other dragon intrusions. If a dragon attacks your city bent on eating people I'm prepared to personally teleport it off this planet and not let it back until and unless satisfied it will stop killing people. The thing I need to get across here is that the dragons, also, are people, and we can't privilege you over them by fiat. If your people try to kill dragons..."
"Well," says Nelen, "right now, none at all. But now that we know dragons are people, teams like mine are going to go talk to them, and they will get the same offer you have. And if you do want to join Vanda Nossëo, for the defensive support that extends beyond me teleporting dragons out of the way as long as I'm posted here, for the universal basic income guarantee... in Vanda Nossëo, killing people is illegal."
"I think, that I need to take a step back from this and consider for a time. I also think- You will find this stance on dragons to have quite the effect on every civilized human you meet here. Preparing this world for the star travelers' return is our reason for existence."
Pause. "You say 'people', and use it to mean 'beings that can speak'?"
Amazing! Nobody happens to pick up on the idea that she could make other things, especially.
Meanwhile, the terrified dragon quickly retreats to her den. Yes, she's lingered far too long. She smells the hunters getting closer every day, and now flying humans! It's time to go. At night, when they can't see very well.

They are not pardoned! They snuck up on her without even smelling like anything! Her mom was right, she got too curious and now she's going to die.
She will be very very scared and very very still and quiet and hope they go away.
A wash of sensation, osanwe-like but not in words at all,
That's a lot of shiny things. Very impressive and intimidating. She is extremely scared but will not give up without a fight! But also she will just leave now if they want to let her do that! (So she can grow big and strong and come get revenge later because they CHOP DOWN FORESTS and ENSLAVE ANIMALS and KILLED HER MOM.)
She projects a sunny burst of PRIDE and a trilling, happy tune like birdsong. Yes, that is an excellent deal, she will answer many questions in exchange for a shiny thing. If they promise to let her go after.
