Well, aside from their new mage, that is. She's bored, and curious. Making portals to known places is straightforward enough, with the magic she found, but that's far from the limit of what it can do... so one day, she slips away, portals off to a different cave system - one can't be too careful, after all - and experiments.
Temperature roughly the same... gravity roughly the same... air the same, not into stone or underwater or in a volcano or on top of a mountain... but, instead of patterning it after a place she knows, what happens if she only specifies those things, and lets the innate patterns of the spot she's casting on do the rest? Particularly this one part, which seems to specify the world...
She finishes the spell, and hesitates for just a moment before activating it.
Kiri would like her bellpull on some moderately portable object that she doesn't need in its portalless state. She finds something, eventually - there are a lot of arguably useless things in this house, accumulated over many primacies.
And lo, there was a bellpull. The kobold pops over to her cave for a minute to finish setting it up, then returns to test it - excellent, that will work nicely.
And the kobold goes back to her tribe for the evening. In fact, she'll spend the night - by the time she's done setting up a second bell and showing the bellpull system to everyone who's curious, it's fairly late. She's back at Kiri's house in the morning, though, for one more day of spellcasting help.
Kiri offers her breakfast, and then: "Did you get the learning spell while you were gone?"
She didn't, but she's pretty sure she'll have it by the time she comes back to cast the big portals - her tribe's mage is a nervous sort and wants to see how the rest of the tribe reacts to this new bell thing first.
"Okay. No hurry on the big portals, though. The stone arches aren't done yet anyway." She could get Alser to help but she's not in that much of a hurry. And doesn't want to split the money if she doesn't have to; she likes Alser, and Patience, but she has plans, damn it.
Breakfast! Spellcasting?
Spellcasting! Kiri turning pieces of paper into portals and then setting the pieces of paper on fire.
The kobold hangs out nearby, reading and intermittently thinking about bellpull-friendly trap designs.
Kiri has nothing to add, having never really thought about trap design before, but she scritches the kobold and makes portals until lunch, and then they have lunch, and then she scritches the kobold and makes more portals.
More scritching, more portals, more reading. The kobold is actually getting pretty decent at the reading, all things considered. And then after a while it is dinnertime.
Portals! Offering the kobold more difficult books and defining words in them as she stumbles thereupon!
Reading! More reading! Hesitant bell sound from the kobold's bracer! She should probably go see what that's about.
She's gone for a while, and comes back grinning. The magic-seeing spell, which is also the training spell: she has it.
Sure, here. It works like this: here's the bit where it detects magic, and here's the bit where that's used as a trigger for making light - very dim and in front of your eyes, for magic vision, or brighter and emitting from a rock or whatever if you're training with it. (And the magic detection can be used to trigger other things and other things can trigger the lights, too.)
Hmmm... it would be hard to make secret messages that way - hard to get enough detail on where the light is and isn't - but not impossible.
She can burn words into paper. Can she chill words into magic paper?
Maybe! The local magic is different enough from the kobold's native sort that she wouldn't be very surprised either way.
Kiri tries it: invisibly drops the temperature of thin lines on the paper to spell her name.
