Eefina has this collection of various small items which she would like to keep together as a field utility kit she can wear as a part of her gear, and this handful of larger items she would like to be able to carry unobtrusively but not literally wear all the time.

"I have several strong options for a durable and accessible field kit, and it's fully customizable given a short time for modifications. I will be glad to show you. Any color, too - I can match your outfit easily or choose an accenting color as you wish. The other request is a bit more open ended. Is unobtrusiveness the primary criteria? Carrying capacity? Price?"

Eefina considers her options.

For the field kit, she decides on a white leather hip-pouch that blends in with the smaller pouches already a part of her gear.

The bags of holding really are too expensive, she decides. To carry her camping supplies she'll just get a backpack / backrack that'll stand up to being dropped on the ground a lot and/or kicked around in an emergency.

They have a variety of very nice and durable backpacks in fancy materials, with a number of convenient little enchantments that are a lot cheaper than a bag of holding. The seller gets more animated and interested as time goes on, almost reveling in his chosen trade. Tret offers his advice on what makes a pack good for travel.

Eefina follows advice and picks one.

After paying and transferring some of her earlier purchases into the pack, Eefina is ready to see miscellaneous other shops that Tret thinks are interesting.

"I think I'm pretty much shopped out for the day. Not that it wasn't fun. Unless you want to see a toy store or a candy shop?"

"I guess I don't need to see a toy store or candy store." 

"Eh, I could use a treat. Candy shop. Then I'm gonna go see my brother."

Candy shop! They have an amazing variety of flavors and formats, some slightly magical and others only seeming that way. Tret gets crunchy mints for himself.

Eefina tries some candy! Gosh, the variety. She's particularly taken with these chocolate-coated wafer things.

After that diversion, though, she will need to get back to the Academy for her afternoon sorcery class.

They're taking things pretty slowly again.

Except the teacher notices that Eefina trivially blows through all the Windsight exercises he had planned and gives her a book about magic identification to read and says, "I'll give you a free gold-level tutoring session after this class if you'd like."

Eefina nods eagerly and devours the book.

And then she can come to his office. 

"Hello, Eefina. Frankly speaking, you're a prodigy. I wouldn't be surprised if you've already met the level requirement for this class, in essentially just the first lesson. That kind of growth rate is the sort of thing you hear about in legends! And I want to be perfectly honest about my motivations here, one-on-one teaching a prodigy who learns very quickly is good for my own Skills, and helping out promising students is usually a good bet. Now. You seem happy to learn, what's so great about sorcery in your opinion? What would you like to learn?"

"I don't mind! I like learning, and sorcery is quite possibly a local maximum of both interesting and useful! I, um, figured out earlier that I'm probably best with azyr, so, that?"

"The wind of the sky... Shaping the Winds of Magic is a challenging task for most, indeed. And a powerful and fascinating and dangerous one. Few things are closer to the root of reality than sorcery and wizardry - just system philosophy, in my opinion. So, let's show you how to cast a cantrip and depending on how quickly you get that we could move on to some Azyr-specific spells..."

"Like this?" Eefina interrupts, tugging on a bit of ambient azyr and flicking her fingers one-two-three assemble-the-Noise.

"-Yes, like that. Do you know how to draw the Winds into yourself, to store them for later? Know any more cantrips?"

Eefina shakes her head. "I learned that from watching a friend do it. I haven't tried to store Winds for later yet. How does that work?"

There are mental exercises that mostly involve focusing on something specific! The teacher is happy to walk her through them. ...Though Eefina should definitely not try multi-wind casting or holding more than one wind at a time until she's at least level 50 in the relevant skills.

After she has that skill down in a remarkably short time, he has them relocate to a practice room much like the one the Observatory Tower shopkeeper used, which drains away excess energy constantly. Now she can try to learn a proper spell.

"The simplest non-cantrip azyr spell is the humble Lightning Bolt. It isn't actually the easiest to learn since it requires channeling a significant amount of energy, which is usually the bottleneck for novices, but you can handle the Wind and it is conceptually simple and direct, so you may prefer it over something like Azure Blade if you're looking for a combat spell. Or would you rather learn something suitable for utility, or some basic divination?"

"Is 'all of those' an option?"

He laughs. "One at a time! Even you should focus on perfecting one spell before learning a whole repertoire, and you can get the others when you drop my class and sign up for the advanced one tomorrow."

"Okay. How do I Lightning Bolt?"

He's happy to show her! It is indeed a lot harder than the cantrip. And azyr almost has a mind of its own, twisting and flashing away from her. She'll probably flub it at least once, but that's why they're doing it here, where the energy can be grounded mostly harmlessly.

Seeing it in action, it is more than a simple electrical discharge. Azyr is chaotic, but it is the chaos of inspiration; the assembly of many disparate thoughts into a suddenly-coherent whole. The moment of electrical discharge is an epiphany, albeit a very simple one.

Eefina points at the target, and inspires some Lightning.

The lightning strikes out - and grounds itself on several of the metal rods studded into the ceiling to help drain away energy instead of the target.

Her teacher makes an impressed sound and gives precise and understandable feedback on the imperfections in her form and casting. He keeps up the feedback as she starts forming a new lightning bolt. This one gets a bit closer. He adjusts a control by the door, releasing more of the Azure Wind into the room.

The sixth bolt hits the target dead-on despite the plentiful metal studs in the room.

Awesome.

Eefina wants to practice some more to make sure that wasn't a fluke, but after that, "Can I learn that basic divination too?"
