"… Sure," responds Theo. "Do they usually wear masks? I know approximately nothing about them except you said something about them not believing in souls."

"They live in the Bikanel desert so they usually need the goggles and breath masks to walk around, and we have magic to, like, not feel too cold or too hot so people kinda just wear the same kinds of things everywhere."

"You have magic as in, it's available to everyone – presumably as spheres? – or specifically the Al Bhed?"

"Clothes are generally enchanted with that."

"They weren't in Zanarkand, we used machina for heating or cooling, but I got enchanted ones when I got here."

Nod. "I can cool the area around me if I need to – or heat it – but anyway things don't get much past uncomfortable."

"I think the spell was invented for pilgrimages, summoners can't really carry a lot of luggage with them so a way to have a small number of sets of clothes fit all weathers was necessary."

"It definitely sounds useful," he agrees. "So – pyreflies apparently sometimes form spheres, which you can use to get some magic quicker, but I think Tidus said you could do it without? And – how do you aim for being able to enchant clothes for temperature, are there techniques you can do to get certain magics or do you just sit in a desert for a while and hope you spontaneously get the ability, or do spheres have a random chance of that…?"

"In general you want to imprint your thoughts and emotions on the pyreflies to get them to do stuff for you. You don't get spell spheres, though, there's only one kind of sphere that teaches you generic spells, and you need to figure out how to internally use that sphere to get that spell. The more common ones there are instructions on how to learn and what to focus on and what you need, but new ones need to be figured out from scratch."

"Oh, so – do you have a comprehensive list of the types of spheres, then? Uh, I'm guessing there are multiple types of spheres, at least – there's the strength one and then the general magic one?"

"There's lots of them. The ones that just kinda activate magic in you are power, speed, mana, ability, and fortune."

"Do dresspheres just appear in the same way, then uh, you get to pick what you look like the first time you use it or something? Or are they specifically manufactured somehow?"

"Dresspheres are all manufactured, you need to imbue pyreflies with very specific magic and very specific feelings and then use those pyreflies to make the sphere."

Nod. "Any other sphere types like that?"

"Like what?"

"Like dresspheres, ones that have to be manufactured specially. I mean, I was treating spherecorders and the things they produce as distinct – I'm assuming they have to be manufactured somehow – but other than dresspheres and spherecordings, are there other spheres that have to be manufactured?"

"Hmm, I dunno, actually. I think maybe purple or yellow spheres? They kinda tweak your magic."

"– Do you know how they tweak your magic? I'm not clear if you're unsure about whether they're manufactured or unsure about them in general."

"Whether they're manufactured, purple spheres sorta open more rooms inside your soul where you can use red spheres, and the yellow ones let you enhance your magic more efficiently and without needing to use it to make it settle."

"Huh. Are they temporary? And – I'm guessing they're hard to produce, however they're done, otherwise I'd expect lots of people to have and be using them?"

"Not temporary, and pretty hard, yeah. I've never seen one."

"Sounds like it might be useful to look into, though. If there's any convenient way to do so. Which is possibly aided by the fact I can make expensive materials quite quickly? – I'm not clear how much the sphere slot things matter for what you do – I mean, fighting fiends and stuff – but I'm guessing they're probably helpful?"

"What do you mean?"

"I'm guessing fighting fiends would be easier if you had extra slots for strength spheres? And I'm guessing that purple and yellow spheres would be useful at least in part because of that? And while they're rare they're probably easier to find if one has lots of money, or easier to find things out about if one has lots of money, and I assume there are things that are highly-priced here that I can probably produce quite easily?"

"...oooh."
