And they get curious stares, rather a lot of curious stares, mostly from people they recognize -

"Is there anyone here who can explain themselves -" Fëanor shrieks at them and so someone steps warily forward and starts explaining, "uh, okay, there's a we-think-infinite multiverse with lots of copies of the same worlds..."

Elspeth shows up. "Oh my god thank goodness," says Wilhelmina, "cool, do your thing -" And she disappears.

Elspeth can do her thing! She has an explanation composed in something resembling a sensible order but if the undead Elves would like her to put anything in particular first she can do that.

No just start please right now.

She starts, at quite a clip. Multiverse! Ardas! Variously interrupted timelines! Their Arda is old as balls and therefore sucks! The peal! Magic and science and non-Arda worlds!

"Thank you," he says when she is done explaining everything. "You are actually useful - where can we get computers -"

Depends if they want the chiplocked kind, those have to be demon-installed, if they just want regular ones they can have some right away.

Right away sounds lovely. Maybe the chiplocked kind later.

So she grabs them all computers. Computers work like this!

It does not take them too long to pick up, even though wow, weird.

Anything else need explaining or are they good?

They would like the spells she mentioned, can they have those.

They're out of eidetic memory necklaces right now, people keep wanting eidetic memories.

Yes but this is important.

...they're still out of necklaces. Elspeth can't even loan them one, she just has an eidetic memory all the time.

When are necklaces expected?

Nobody's told her.

Okay computers are all for now, then, thank you.

They're welcome! Off she goes

And Vanda Nossëo's Fëanáro finds them a little while later and launches into a faster-than-reading-about-it explanation of modern physics and computing, at which Celegorm snorts disgustedly and says he'll go off exploring, and after that there's a steady trickle of new arrivals to acclimate.

Elspeth manages to show up reasonably promptly for all of them. (Indestructibility: it has broken the yoke of her sleep cycle!)

And after a little while Vanda Nossëo concludes that, yep, these are perfectly lovely people when no one steals their things and yokes them into horrible efforts to retrieve them, and then, what do you know, they finish up some new eidetic memory necklaces (sorry for deceiving you Elspeth but you know why we did it).

Yeah that's totally reasonable.

And, uh, whenever relevant persons are ready it's just the Maitimo now.

Are they going with subtle arts sensory dampening in lieu of a stint in a Lórien altogether?

Perhaps in addition to? Lórien can make itself soft or dark but apparently breathing and having a body and so on are still unpleasant.
