"The cold one doesn't need to be particularly far below freezing, but the hot one should be as hot as possible unless you can get it to over a thousand degrees in which case any hotter would just be stupidly dangerous. And lots of surface area, maybe I give it spikes. I can run water over it and have it flash to steam... What do you want for payment?"

"What is exactly your budget or what is in offer?" She eyes the machinery, "Besides covering material costs and maybe meals if I stay here long enough, I'm not sure what you can give. Is your robot-armor thing complicated to pilot for a a spin around the lake? Or maybe your pokemon?"

"Walkers are kind of hard to use, yes... And Feume has to like you a fair bit to let you ride him. I've got a bunch of little gadgets, though. If you need electricity sometimes, to charge small to medium devices if you're out in the wild somewhere, I could turn the small plate set into a little miniature generator and fridge? I'd need to see your world's electrical plugs."

"Oooh, electricity is a problem! Witches have their own society and mostly haven't caught up. I bet you that no one ever thought about make a gas-exchange engine before. Maybe something steam powered, except my clan's lands uses gasoline generators, so I don't know."

"For this I was thinking something really little and light, that you can carry with you and hopefully never needs to be fixed."

"Not needing to be fixed would be cool, but if it could be something we can do ourselves, or at least something we can get the parts on a store and assemble ourselves, it would be even better. Bar can probably give tips of common materials."

"I already talked to her about stuff available in your world. Well, lemme sketch some designs..." She seems to prefer using her computer in a very sketchbook-esqe way.

"Cool. I will go back on improving on how to enchant the plates. At some point we'll need to see if the spell sticks and there isn't a better way than wait around for a couple hours."

"Oh, yeah... I don't really want to go through all the effort of making my big one unless I know it'll stick."

Temperance keeps working on the disks. She manages to get the require temperature for a brief moment, and then starts working from there, and eventually she has a couple of disks for the two hours test.

Walta has been poking at designs on the computer. There isn't really simulation software for engines in the Sinnoh region, though, so she's going on intuition for half of it.

"What should we do while we wait for them to hopefully not fail?"

Temperance shrugs. "Dunno, I could go for a swim."

"Mm. I'm not a fan of the water but I should probably go sit by the lake and read or something, so milliways doesn't decide to separate us for the fun of it."

"Sure! Would you have an issue with me swimming naked?"

"Um. K-kind of slightly?"

"Oh, sorry. Witches don't have problem with nudity and cold, it can be hard to calibrate others' expectations."

"Maybe I'd better stay inside if you do that."

"But then there is Milliways' time thing. I could swim with my silks on too."

"I just- Urgh. But then you have to swim with something dragging along." She takes a deep breath. "It's not- I mean, if you don't mind, you don't mind. I'll get over myself."

"I don't mind. I can't, actually. When I said it was a witch thing I meant it is part of our biology to not care about nudity."

"Even if some creepy guy started staring at you?"

"Well, that isn't meaningfully better or worse while I'm clothed and I have magic."

"Well I got all flustered becaaaause I am kind of attracted to girls.... But it's not like I don't have practice ignoring it."

Giggles. "I won't mind, really."

"...Then okay I'll sit by the shore and start putting together some stuff I can use for other things if the plates don't end up working."
