"Yeah. We make our humans learn for the military reasons, I guess maybe otherwise most of them wouldn't bother?" They clean blood and soot off themselves and put on shirts.

Shirts are great.

And they approach the city.

A very large very fast metal thing on rails zips past them, stops a little ahead of them so people can get on, then zips on again.

"Oooh, clever."

"Yeah, neat."

Twenty people come soaring through the sky and land on the platform for the rail thing. The bug-winged person zips off and the others board the next rail thing. 

"This place is so cool."

"It's so alive, it's so convenient - wonder how much of it we can take home - do you want to try the rail thing or shall we walk it -" 

"I'm a little wary of the rail thing. I bet it could be done by steam, if not so fast, though."

"Oooooh. Gates are more convenient but do have, uh, the one disadvantage." They keep walking. A bat-winged person lands near the edge of an empty square of concrete and suddenly it's full of shipping containers. No one blinks at this.

A very tall blue-grey humanoid walks by with a little box which is singing a magic song for cold. Findekáno bounces this to Cor - "So they have our magic in addition to -"

"They have so many things. Are all the things native or do you suppose -"

" - it almost makes more sense to presume they figured out the dimension-hopping before we did, did the thing we're planning to do -"

"I wonder if they have a procedure for visitors!"

"Do you want to ask? 'Hello, where's the interdimensional visitor's center?'"

"It might be worth a shot!"

He waits until they're closer into the city. The rail lines, it appears, tunnel under it. There's an information booth, staffed by a red-haired woman and her husband trading off their newborn baby. 

"Excuse me, is there a center for interdimensional visitors -"

         "Silver building at the corner of 48th and Skyline, it's about a mile from here, would you like walking or train or teleport directions?'

"Ah. Walking."

        "48th is six blocks that direction and then turn left and go three more."

"Well that was easy," says Cor, walking in that direction.

"Yeah. Wow. How many worlds do you have to have visited before it's barely even a remarkable question -" Someone in front of them disappears with a pop. 

Cor jumps. "Dozens?"

"I suppose I could ask someone that too." There are shops. They seem to sell pieces of reinforced glass with words glowing on the surface, and groceries, and table space to sit and do things with your glowing reinforced glass. 

"I want to know what all of this is."

"Me too!! Maybe we can requisition a guide at the interdimensional visitor's center."

Someone bumps into him in the streets, murmurs "so sorry, your grace," and bustles off. He stands quite still in confusion.

"...maybe people just call Elves that in general?"

"Maybe? Since we have kings at all and no one else does - that'd be kind of funny - or in their Quenya it could've turned into more of a generic -"

"Yeah, something like that."

But he frowns. They walk on. Vendors are selling delicacies of various kinds. There's a bat-winged man lounging on a fountain who appears to just be making things out of nothing for people by request.
