"Well, I can cover him with an extended mind blank for two days - discern location might actually give the sort of result that does not tip off Tar-Baphon at all, if Marit mostly sticks to cities that exist today - Perhaps I should try one on one of Korva's companions that didn't come with."

"Oh, that's a good idea. Also suggestive about what kind of magic we should expect to function across-world. They tried Sendings, obviously, without success. But the Raise Deads worked, which I wouldn't necessarily have expected."

"I'll go see who we might be able to test it on."

Inside the Mansion, she first goes to look for Korva in the private sanctum room, unless she should run into someone else on the way there.

Heleer is in an antechamber doing Legend Lores, and nods to her, but does not particularly convey a desire to talk, plausibly because he has guessed she might have some questions.

Korva's out of the private sanctum room, by now. She figures her next order of business is probably talking to Heleer again and seeing if he can learn anything useful from her or from the memory of her not-a-teleport, but she's been checking on Aivu, and hasn't quite gotten around to it just yet.

When Korva's not in the private sanctum Alfirin keeps looking until she finds her. It doesn't take that long, since Korva is not actively trying to hide.

"Knight-Commander? Do you have a moment?"

"Sure."

"My name is Alfirin, I'm a wizard working with the Shining Crusade. I'd like to try to use discern location on one of your companions back on your world to see if the spell can work across that dimension. I will need an item that once belonged to them to target, do you have anything?"

"Oh, probably. Uh." What does she have that used to belong to someone, does she have anything like that? - well, half of what she's wearing, but most of those people are dead. "Do gifts work? Do you know how long they had to have it?"

"Gifts generally work if it's something they made themselves or owned for a time before gifting it. If someone bought a ring of protection for you, it wouldn't count, if they made it it would, if they owned it for a time and then acquired a better one and gave you their old one that'd work. It's not very picky, about a week of ownership tends to do it."

So not the scarf. She's gotta have - "Oh! I gave Heleer some notes written by his other self. That ought to do it, right?"

"That seems worth trying, though - there's the chance that just gets us Heleer, and if it fails outright it's less informative, since your Heleer might keep himself mind blanked."

She'll try it.

"No result. Anyone else I can try who's not a powerful wizard? And ideally not alive right now?"

"Nnnnot off the top of my head. ...I'm gonna ask Woljf if he's stolen anything recently, I bet he has."

What, him? Steal? From the crusaders? He would never.

....but would it work if he had an item that probably used to belong to someone else and he didn't know who that someone might have been?

"I don't think so, I think you need to identify the creature?"

"Would it work to find a person who had something for some amount of time between probably stealing it, not that I have any way of knowing that, and giving it to me. - who you, uh, aren't actually trying to find, right, it's just a test?"

"It's just a test. I... don't really know whether that would work? I guess we could try it?"

Woljif makes a face. "Of course, some people are less than perfectly enthusiastic about their locations being known to strangers, not that those people have necessarily done anything wrong and don't just value their privacy. - Oh! Hey! I have a cup I was borrowing from Seelah. - She was showing me a trick with it, I really wouldn't steal from Seelah. I value my life too much."

"That works. Probably. Thanks, Woljif."

She has a cup that probably once belonged to her friend Seelah. Will that do.

Yes, that will do.

...Still no result. So the spell doesn't work across universes, which is convenient.

"Well, thank you for letting me try this. Anything else you need from me while I'm here?"

"Uh, not unless you think you have a way of learning anything about how the not-a-teleport works that might make me more confident that I can predict where it'll drop me next time."

"Not without seeing it done, no. Best of fortune to you."

"Thanks."

Well. In that case she'll talk to Heleer about it, but she's not very optimistic. Regill's not wrong that something completely unexpected happened, and that something unexpected might happen again... but it's probably the sort of power that you have to trust in, and hope it's friendly.

Still. She ought to try.

Heleer doesn't have much in the way of guesses, either. Perhaps she wants a tuning fork for the Material so they have some hope of Plane Shifting back here if it takes them to another plane. They probably don't want to do it from inside the Mansion in case that confuses it. 

"Iomedae'll obviously look pretty hard for you, if anything goes wrong. But - there's nothing obvious to attempt in advance, really."
