"Well, you're the one who's world is at risk, so if you feel it's safe then I won't argue, given how convenient for me it would be if it worked."
She pauses.
"I don't have elbow-fingers, that's a figure of speech."
"I'd be happy to talk to a few of your researchers about my castle, if they would like more details. In the meantime, I suppose I'll do some writing... A desk won't fit in here, but I can use the back of one of these encyclopedias, they're certainly thick enough."
"Nothing at the moment, thank you. We'll have to discuss possibilities for circle expansion or wanderings about at a later date... Oh, wait, sorry, is it possible for you to either get my teacup and this stain out of the circle, or send me some cleaning supplies?"
Isabella nods. "Alright, in that case I have no further requests." She settles back into her chair and starts paging idly through the encyclopedia.
Isabella is glad of this: she has little enough room without spilled tea taking up a quarter of it. Now then, time to continue her education on how this world -Elcenia, right- works. Let's see, what about spirits? Surely there's something on the local deities and how magic works. Hmm, probably the magical overview first: she's less concerned with local culture.
There are wizards. They do assorted spells, with gestures and words, through their channeling capacities. There are witches, who make potions. Merfolk have two unique kinds of magic, one which changes colors and one which manipulates energies like heat and light and current. Dragons have their own magic. Some of them have more of it. Keo has lots.
Keo is significant enough to have her own entry in an encyclopedia? How intriguing! Isabella looks at the page, then sighs. Well, she knows what to ask for next time Keo turns up: bookmarks. Rather than go on to read more about some specific kinds of magic or dog-ear the page, (shudder) she quickly skims Keo's entry.
Now then, most of these sound like things that mages from her world might do in one way or another... Confusingly, the local mages are most like her world's shamans, at least from the top-level overview. She examines them in more detail.
There are fire, earth, air, and water mages. The procedure to almost die and become an air mage is the least unpleasant because you don't have to actually hit the ground when falling from your designated height. Mages have near absolute control over their element, to the point of ignoring some standard wards. Fire mages are a core part of most Elcenian firefighting arrangements. Air mages can fly. Water mages can breathe underwater. Earth mages can breathe underground.
Isabella is starting to form the tentative hypothesis that spirits don't exist here. Let's see what the encyclopedia has to say on the subject.
Well, that makes some sense. Many of the larger spirits on her world have religions and customs built around them. What can the local priests do?
Actually, there's a thought. This building is probably owned by Keo, right? The room is her child's, at least, so by the regular rules...
Keo, mind telling me to leave the room I'm in? I promise the worst thing that's likely to happen as a result is I feel a bit uncomfortable.
I'm testing to see if thresholds exist on your world. If you revoke my status as a guest and they exist, I ought to feel that as the local spirits metaphysically 'weighing me down.'
