They do not have those, those are super expensive and rare.

Okay. Do they have a world map or know where she could find one?

Oh yeah there's probably one of those in the materials for tourists that're here somewhere behind the desk. 

She finds it after a moment.

She stares at that for a while and then asks if they could translate the scale for her.

A mile is the diameter of the great dome outside, or a tenth the distance a soldier can march in a day, or about ten city blocks.

Okay. This is a side plane then. That's complicated. She thanks the innkeeper and asks about where she could get paper.

There's a shop right down this street.

Then that is where she will go.

They have regular paper and ink and also paper and ink for spellbooks which is ten times as expensive and also some spell scrolls.

NOPE not touching those just some normal paper and pen please.

Sure, that's cheap, here she goes.

Back to her hotel room to write all evening and then try to go to sleep to get on local time.

There aren't other women in the streets on her way back. The city quiets substantially at night.

She's not paying that much attention to the gender balance.

She bought a lot of paper and will need a significant fraction.

Fëanáro is certainly going to try to come after her but will probably not be able to get anywhere on that for a long time so he's not in immediate danger. She doesn't dare cast anything, but her boots and watch work and haven't caused any problems yet. It'd be... pretty darn antisocial... to sell the boots and buy locally enchanted replacements, because if she did that it'd be because she was worried they'd explode on her or something. She can't do without very effectively, so she will tentatively hope these continue to work.

She doesn't dare try to go back to Arda, but it's probably safe to try to get back to the Imperium. That will just take planar transit instead of an airship. That's going to be expensive, probably more than the value of all her jewelry even if she doesn't eat through any more of it with room and board expenses. She's not an adventurer, but the idea deserves a few minutes' thought, it'd be the fastest way to make money... she isn't an effective enough psion to adventure on that basis and certainly can't lean on being a wizard, and she doesn't have a therapy license and even if she did she wouldn't have a local one. Plus going on an adventure in her boots would be more dangerous than walking down the street in them.

The Valar are stupid and terrible and she HATES THEM.

It is probably not safe to predicate any major action of any kind on Valinor's existence. That means no message for Rúmil (sending one to Fëanáro probably wouldn't even help). She can almost certainly keep braiding her hair and wear these robes till they fall apart and try to reproduce Tirion street food when she has a kitchen but nothing else.

She's been gone for a long time, so everyone back home thinks she's dead or worse, so she doesn't have to be in a particular hurry because the issue's moot from their perspective.

She needs to know how much a plane shift casting costs around here and maybe look into getting a local therapy license. Or she could do translation, maybe, she hasn't sensed any other subtle artists and while it doesn't seem unheard of it may be rare on this plane? So maybe that's a niche.

She could fall asleep now. She goes to bed.

No one interrupts her.

She goes and gets breakfast in the morning. She asks if the innkeeper happens to know how much plane shift castings cost.

Four hundred fifty, five hundred crowns, some people will quote her more but unless she's in a roaring hurry she can generally find something at that price if she asks around enough. 

She counts what she's got, after returning to her room post-breakfast.

Thirty eight. Selling all the jewelry might get her reasonably close.

She'd really rather not, but she'd better find out if she can finagle it that way sooner than later. Out she goes to try to find quotes from wizards.

Couple people will quote her five hundred.

She goes back to the jewelry shop to have everything on her appraised.

They'd go as high as, like, four hundred ten.

Okay. She will try a few more wizards and a few more jewelry shops and have lunch and try a few more but if she can't make ends meet she will spend the second half of the afternoon inquiring about such a thing as a therapy license or a niche for her translation services.

What's a therapy license? She can ....therapize people... if they want to pay her to do it. Is this associated with the counseling services offered by some churches? This country's leaders are chosen by Abadar and Abadar is lawful neutral but all non-Evil and non-Chaotic faiths are allowed here and many of them have at least a little bit of a following, she could probably find hers. 

Comprehend Languages is a first-level spell and doesn't require an intermediary so it seems unlikely that'd be very lucrative? Telepaths are definitely wanted in the civil service, though, for interrogations and so on, and one expects it'd pay absurdly well.

She can get an offer for the jewelry as high as 430 and a offer for the plane shift as low as 450.
