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.
"My name is Tanaka Natsuko, and if you want to be polite it's Tanaka-san but if you prefer more casual address Natsuko is fine. I can create a new building in a few seconds for us to set up shop in, and then someone will teleport down a starting stock of things we think people might want around here, which we'll trade for personal anecdotes or stories or songs."
"Tanaka-san, thank you for clarifying. I am Minister Ferron or Sir Ferron. ...How strange. If you wish to be paid in stories that is not our business. I think you had best demonstrate to me or the Guard that your products are safe first, and make sure to warn people about those that aren't. We do punish merchants who sell bad goods. Perhaps not a spot in the market square if you intend to... Raise a new building. With magic I presume?"
"Well the first is just this way, not far from here. The usual way we tax merchants won't work, we charge an import duty by the wheel and leg, but I'm honestly not worried you all will shortchange us when it comes time to figure that out. Instead let me ask, many of the sick and injured aren't well enough to push through an excited crowd for their healing, either, would your healers be willing to make visits?"
"I think we can handle that. The guard or the priests or the scribes... The scribes. They tally the sick and cripples as part of making sure we have plenty of food, so even if they don't already have a list they know how to go about it."
They arrive at a large open square, rough and uneven stone with a few stalls and wagons set up in rows along one side. "Well, here's the square, and there is your spot just there, see that empty space?" It's a house-sized gap in the rough stone and wood construction, with wild grass and bushes growing in it.
"Mm-hm!" says Natsuko. She takes a picture of the building, and a man appears in just a flicker before he's gone again, leaving behind the accompanying boxes. She pulls them into the shop; they all follow her as though feather-light. Then she sticks her head out and says, "Hey folks, what would this store sell in your wildest dreams?"
Everyone wants one! They're kind of crowding and shoving for the chance to be next! Until the guard shouts out that they're civilized people and should be ashamed of themselves and he'll take them in for assault if they get too rough, after which they get a lot subtler about it.
This lady thought her husband was cheating on her but really he was out fishing the whole time. This teenage boy once saw a BABY DRAGON (his friend just behind him in line calls him a liar and says it was a vulture). This tired looking woman will sing a lullaby about all the plants waving gently. This man explains how swamps are sacred and bless the faithful with gifts sometimes. This man tells them about a rusty metal tunnel he found on the mountain once.
Lights for everybody!
They start unpacking once people have gone off with their new lights and the crowd is thinning. They have spices and snacks and bolts of fabric. They can install translation magic that'll let you use and understand any language. They can heal - Natsuko can handle most things but anything she can't handle Nelen can. They have little space heaters. They have magic rings that will make it so you won't get anyone (including yourself) pregnant till you take it off again.
The crowd doesn't really thin, though it does get more orderly when a few more guards show up. People are playing with the lights and shining them in each others' faces and milling around the square.
Allspeak isn't very popular. These people seem a tad xenophobic and incurious about the wider universe, more interested in the goods than in stories of other worlds, and the stories lean suspicious of foreign things in general. Healing is very popular, lots of people have scars or old sicknesses of some kind. The four scribes who are supposed to go around taking pictures of sick people arrive and look around confusedly. A few people want the rings but opinion seems kind of mixed.
Exotic spices are excellent! They are soon putting pepper in porridge and cinnamon on bread. An impromptu feast seems to be gearing up in the market square inspired by the spices, block party style. Someone is setting up to butcher a bunch of goats right there in the open where they're building big fires.
Zanro shows the scribes how to take pictures and issues each one a camera and tells them that if they come back with pictures of the homes of people too ill to come by for healing, the pictures will make it quick for Nelen to visit.
Cassiel catches up and asks a little hurriedly if they'd like her to make some meat by magic for the feast right there!
