"I don't know what the local wizards are doing but it's probably not 'prophecy actually still works far enough north, no one noticed'. Maybe I will predict many good things next year, by which time hopefully we'll be home."

"Yeah. Seems valid to me."

After breakfast she will go share Taldane with the man indicated.

He is busy talking with some other people (and then has to be convinced to talk to her by the first woman), but then he can accept the spell and talk to her.

"Halla tells me that you are a great witch."

Wizard, she does not say. "I don't know how your people measure the powers of magic-users. At home I was an enchanter of magic arms and armor."

"Strange work for a woman," he says, but does not sound altogether disapproving. "What magic do these weapons have?"

"They are deadlier, and find their aim more easily, and cannot be broken or tarnished or rusted. I cannot do that work here, I need special metal to hold the enchantment, but a wizard here might know of the metals I need."

"I know that Hauskuld the White is a wizard of some power. He lives at Foss, to the south. But you may wish to go to Reykjavik, and speak to the court wizard there, if you are foreign."

"I might want to do that. But - I think I would like to talk to Hauskuld first, if that is all right." They'd better have their story about which country they're from very straight before they go to the court wizard.

"We can spare men to escort you to Foss tomorrow, if you have no business here. It is nearer than Reykjavik. Perhaps Hauskuld will find more reason to make that journey than we do."

"That makes sense. I am grateful for your hospitality. I can conjure us horses, for the trip, if it's best made by horse."

"We do not need spells to reach Foss," he says, narrowing his eyes a little. "Our own horses can easily make the journey."

But real horses have personalities and will be scary to ride. She does not object, obviously. "Thank you. Ah, what stories are told of Hauskuld's magic?" Teleport, please please please Teleport...

"He is known to break curses and to lend men strength in battle, and has often seen the future. I do not know whether he is skilled in the enchanting of weapons. But he is good to deal with, and will deal fairly with you."

Lawful. And Remove Curse is fourth circle for wizards. It's not as good as Teleport but it's pretty solid. ...and the local wizards are all, what, in a conspiracy to pretend prophecy still works? Maybe there were no clerics of Aroden, so far north, and prophecy is sketchy anyway, and they didn't know what happened and just passed on traditions that no longer worked.  "I see. Thank you so much."

"We will ride tomorrow, then. I am told that with some time you can tell men's fortunes."

"The art of seeing the future might be more studied here but I have learned a little of it," such as the fact it doesn't work and hasn't for a hundred years. "I would be happy to see what I can see for you. I will need some candles, and an item that is precious or significant to you. I will not damage it, of course."

Then Thorgeir can offer her the great sword that was given to him by his father, and which has slain many men in combat, if that seems like an appropriate focus for such a ritual.

Yes, that is perfect. (Is it a good sword? It is presumably not a magic sword, though it's not out of the question for a treasured family heirloom.)

Not a magic sword. It looks well-made, and has some decoration on the hilt, but it's made of iron.

She sets the candles around the sword and closes her eyes and casts Detect Thoughts, not particularly disguising that she's casting something, she's supposed to be casting something. Even if there were anyone here with the ability to identify it as a divination that'd be fine.

This gives her a sudden impression of the minds of everyone in the room - a very shallow one, just a glimpse of what they're capable of - and she pauses, at Korva, but - not right now -

- focuses on Thorgeir. Hopefully he is thinking something about how fortunetelling (which doesn't work) is supposed to work (which it doesn't). 

Thorgeir believes that those who are sufficiently wise can tell the future. It is a gift given to people from all walks of life, and to both sexes, and therefore it is not so unbelievable that this woman might have some form of sight, although it is unusual in one so young. He does not intend to place much stock in whatever fortune she gives, because Halla is no great judge of wisdom or sincerity, and no one has ever heard of this woman before, but it is right to offer something to those who have offered a stranger shelter from the elements. Perhaps she will have something to tell him about whose counsel to beware, or what preparations he may take to protect himself from misfortune, or what will become of him if he goes away raiding next year, as one of his friends suggested.

Okay, that's actually extremely sensible starting from the premise that ...those who are sufficiently wise can tell the future...she flicks through hypotheses about why people would believe that, hyper-local god? That's not unheard of - but even the gods don't have prophecy - you could imagine a society with heavy reliance on augury (it's not common in Cheliax, asking someone other than Asmodeus would be suspect and it's hard to even imagine circumstances under which the question would be worth Asmodeus's attention) - 

- she needs to focus, Detect Thoughts won't last all day. Whose counsel to beware she can maybe do. She reaches for the thoughts of other men in the area.

Most of the men in the area are working in the fields, which are large enough that they are mostly out of range. A very old man is copying a manuscript in his room, the long way, and thinking about how his back hurts. (Perhaps more helpfully, Thorgeir is occasionally thinking about people who he is already suspicious might be trouble. There's Gerlief of Stóruvellir, who may be angry about an entirely deserved insult to one of his friends last summer, and Asgrim the Red, who lost a suit to his cousin three years ago, and Halbjorn of Önundarholt, who just looks incredibly shifty all the time...)

Sure. 

"I see a man with a long nose, and red hair, and scarred hands. He is speaking loudly, he is angry - I think he is angry about something that has occurred already in this moment, not about something that will come to pass in the future, but his anger is in the future. Trouble may come, but it looks to me like it could be avoided." Maybe this is too vague but he didn't expect her to be a very good fortune-seer.
