"Do you know about any technological innovations that might be usefully transferable from your world to ours?"

She touches her hair. "Not so I could engineer them. And I have the impression you used to be - maybe not as high tech as us but within decades, not centuries - well, our years are about four times longer - before the maelstrom, so I don't know if the level of information I as a layperson can provide would get you very far when your own survivors didn't."

"It's possible we'd be able to get farther if we had more survivors now, though not obvious. We've recovered at least a bit and not much knowledge was preserved."

"I can tell you about stuff we had, just, there are going to be a lot of frustrating gaps, my expertise was mostly in, like, statistical modeling."

"What's that?"

"Predicting things like who will win elections or win games by figuring out what features of the past are predictive and how much."

"Oh that sounds cool and I am interested in hearing much more about it."

"I did a lot of it with technology you don't have here but I can explain some of it if you give me something to write with. And maybe pay me, though I would take payment in some adequately reusable writing surface."

"We have paper and chalkboard, paper and pens and ink are that way on the left, and the chalkboard would be at one of the lost tech stalls, I think the one that direction with the yellow duck made of rubber has some in addition to chalk. I am happy to pay you enough to afford either option - I prefer the pens and ink but they are more expensive."

"I was actually thinking a wax tablet would be really convenient with my power and I wouldn't go through chalk. If you're buying I think it's up to you though."

"I can pay in cash. You could probably ask our chandler for a wax tablet. The local one doesn't have their own stall at the market; only sellers who buy from them. You can find them in town at 10 Norm Lane."

"Are you proposing we go on an excursion to Norm Lane right now or that you buy something temporary for your statistics lesson and I go do that after you've paid me?"

"I can pay you now and we can schedule the statistics lesson for a future block of time when we're both free, if that works."

"Sure. My hours at Elysium are pretty flexible except insofar as I eat there and it makes the most sense to do the dishes right afterwards."

He can likewise find a place on his rather packed schedule for her.

"Pleasure doing business with you. Shall we meet within Elysium or somewhere else?"

"I have a living room but if you're more comfortable somewhere in Elysium that'd be fine too."

"Eefa's been sticking close to me, I don't know if you meant to invite her too or not."

She blinks at the mention of her name, continuing to do her best to not attract too much attention.

"She'd be welcome at my place."

"That okay with you, Eefa?"

She nods. Probably Pelape is correct about her being able to defeat this man if needed so it'll be safe. 

"Okay, we'll be there, then."

"See you then!" And he's off to continue his circuit around the market, chatting with people and helping out when he is able to.

She'll go buy a wax tablet off the chandler.
