"It should be someone who wants to travel, so they can go around to many villages and hand things out."

"That does sound like it makes sense."

He interviews various villagers and comes up with three who are willing to walk around being "the train", whatever that means.

"So how should I divide things up. For now I'm planning to give out the ability to make furniture, clothing and some raw materials for making things by hand. It might be easiest to divide it up that way or I could give each of you the ability to make some of each or I guess I could give you all the ability to make everything that seems kinda boring though."

"If you don't want to give them all the ability to make everything then giving them all the ability to make some of each will still let every village they hit have most of the benefit up front while allowing trade later."

"That makes sense. Okay, so here's the plan, each of you gets the ability to make basic clothing, a third of the weird costumes, a third of the more practical stuff, fourteen furniture sets, silk, thread, and a couple types each of wood, metal and stone materials. You already seem to have plenty of dirt around so I won't worry about that. Does that sound reasonable?"

"Yes, thank you!"

She taps each of them on the head gently. After she does so they should feel a button of sorts at the edge of their mind. "Oh interesting, I almost couldn't do that, I think I only could because you already agreed."

"Huh, maybe it's like drug effects and being indestructible means we need to give permission?" suggests her interlocutor, as the tapped people start experimenting with making things. One starts trying to make a stone house.

The interface seems to allow them to make blocks and cylinders of stone in whatever size and thickness they want up to about ten meters on a side. They can only create things where nothing but air is occupying the space. There isn't any provision for joining materials together but a simple structure with walls and a flat roof should be easily achievable.

This is very exciting, apparently. Somebody is energetically smacking two rocks into each other to get convenient shapes soon enough.

That works as you would expect the stone is not indestructible.

Yaaaay! They are all very excited about the things they can do with all this stuff.

Their excitement is contagious and she's hops about watching them experiment with things. Chandeliers and lanterns will attach to the bottom of horizontal surfaces. Everything else is freestanding. All the furniture is indestructible.

Soon they have replaced all their huts with stone and wood houses and somebody's busily chipping a stone into a tool suitable for carving the wood into a more decorative shape and turning the fabric into curtains over their doors and windows.

She continues to be pleased, she's shaken things up everyone is happy and nobody's come along with to tell her off for messing with balance.

Indeed, no one seems to think there was a balance to throw off in the first place. After a little while the three chosen emissaries set off for neighboring villages, one each way along the coast and one striking off inland.

"So... about concordances? Are those an all the time thing or just a sometimes thing and do they happen at consistent places?"

"Consistent places," says the spokesman. "But only every few years and not all at once."

"What are the other afterlives like? What makes them better?"

"The people in them have powers - to make things on their own, or change them, or move them, and the last one has plants and animals and weather all by itself."

"Those do sound like useful abilities. And having living things around sounds nice. I could do something about that actually... you probably don't want corruption, crimson or hallow but normal grass should be pretty safe. Jungle stuff is borderline... people here are indestructible but I don't think being stung by bees is enjoyable even if you are indestructible."

"It'd at least be something new. Precious little of that."

"That's a good point." She takes out a long staff with what looks like a rose on the end and vines curling along it's sides. She taps it on the ground and a square thirty meters on a side is covered in grass. "The grass will spread and grow some wildflowers on its own. If you use it on mud it'll spawn jungle grass instead. It can also plant trees on either kind of grass, sand or snow. Bare dirt won't do." She hands it over. "If you don't want it yourself I'm sure you'll be able to find someone who does."

"Thank you!" he says, accepting the staff with both hands and bowing.
