Leareth pauses, gestures to it. :Is there something magical in that shop, do you know?: 

...our world does not have magic. 

:Oh, I see. I was clearly mistaken: 

That makes NO SENSE, but Leareth keeps walking, not glancing back at the shop with his ordinary eyes; he does, however, focus on it harder with mage-sight as they pass, trying to decipher what the magic source is. 

It looks like that whole section of the air and the shop behind it are VERY MAGIC, not the way a node is magic - it's much more structured - but not less magic than that. It does not move as they keep walking.

The palace of Tirion is at the center of the city, in what is clearly an older architectural style; stone and arches and stained glass; the architecture has been gradually shifting for a block so it's not out of place. There are no guards apparent; the random orchard workers who found them walk right in.

...This place makes Leareth uneasy. It's hard to pin down why, but he's on edge. 

He glances around at the architecture, and follows the Elves' lead. 

They take him to the throne room. Its ceiling is angled so it's brightly lit by both suns, somehow; there are gemstones in the floor they're walking on; the golden thrones are on marble pedestals. It feels like it really really ought to be tasteless but through tremendous artistic ability they're just barely pulling it off. There are dozens of people gathered on the sides of the room, watching quietly and gossiping in their thoughts, too fast for reading their minds to catch more than glances of it -

- they're sharing guesses about the aliens with each other, and excitement about transit to Endorë perhaps being possible, and speculation about magic - 

Someone, speaking the local language, announces the guests to the King and the Queen. 

Welcome to Tirion, says the King. He is - slightly tense. Probably aliens are good news but there's always the chance that they're not. He is the only person in the room who seems to have thought of that.

Leareth immediately likes him more. 

:Thank you: he says, smiling slightly. :It is a very beautiful city: Pause. :My name is Leareth; this is Ma'ar, and this is Urtho: 

We are very delighted to meet you. We did not know there were peoples other than those in Valinor and Endorë. We are - confused, about whether your creator is our own or someone different. But meeting new people is always an occasion of joy. We hope that you will teach us more of your world and its history and language and art and inventions.

There's something nebulously confusing in this greeting. Leareth sets that confusion aside to poke at later. 

:We are very glad to have discovered your world, and it would be our pleasure to explain our own world - worlds, actually, we know of several at this point:

The King is not very startled by that. Someone pointed it out to him when the aliens first arrived, that there wouldn't be one other world. That sounds fascinating. What can we offer to make you comfortable here while you tell us of that?

:I think we are not in urgent need of anything right now. ...We are still unclear on who or what we followed to this world. Urtho had to return to get me in order to follow, and could not mark the location exactly - we travel between worlds in another plane, where space behaves differently. On further thought it seems likely that the entity we followed went to Endorë instead: 

We do not have communications with Endorë except through the gods there, none of whom have noticed anything.

:I understand. We may want to visit there ourselves - our interplanar travel ought make that straightforward - but in the meantime we can stay here for a few days and share knowledge, if that suits you?: 

You think the situation in Endorë is that urgent?

:I have very little idea if it is urgent, since I do not know what the entity was, except that it was also capable of magical travel in other planes - which makes it seem likely it was not from your world. It may be harmless, but nonetheless I wish to know more: 

Well, we wish you good skill, then. We would enjoy the chance to take a few days to learn of your world and the others you know of.

:- We would likely be interested in further diplomatic contact between our worlds after that. I cannot personally spare too many days here, but we have others we could send: 

Of course. We would be delighted to send some people to your world as well.

:I will need to check back with others in my world, but it is likely we would be interested in that also: 

Probably. Leareth still isn't sure how comfortable he is with this world's set of gods and whatever is going on with the Melkor situation, and he's also unsure how to go about learning more without risking making said situation worse somehow. He...might ask the King, privately, if he can finagle an opportunity for that, it's inconvenient how much these people are in and out of each other's heads and senses constantly. 

IF YOU DON'T ASK HIM ABOUT EITHER THE LANGUAGE OR THE MAGIC I WILL DO IT MYSELF someone tells the King loudly.

The King's face does not change (his wife's does, she looks irritated)

Would you be willing to speak aloud while you tell us of your world, so we can learn your language? We don't know of other languages that evolved independently of our own and we are very interested in learning them.

"Yes, of course. - Urtho, do you want to explain magic?" 

Urtho DOES want to explain magic!

"First of all," he starts, "we have magic from two different worlds. All three of us originate from one world -well, two in some sense, but they are the same world at different times in its history, it is somewhat confusing. Our world has Gifts, which people can be born with, and which grant the ability to do various kinds of magic; all of us are mages, and Ma'ar and Leareth are also Mindspeakers, which is a bit like your people's telepathy. At this time, though, all of us live in a different world, Golarion, which has its own magic - one kind, arcane magic, anyone can learn with study, and divine magic is granted to people by the gods. Leareth and I are both clerics of two different gods and have magic from them, as well as our native Gifts." 

Leareth can relay and translate this in Mindspeech. 

That is kind of a lot of different things that are going on, but the Elves listen attentively (and bounce this to the rest of the Elves everywhere) and start very quietly practicing the sounds of Tantaran themselves, once they've heard enough of them. They look so delighted.

Urtho thinks that they're very delightful! He can talk about magic for a while, and then he pulls Ma'ar into the conversation, since Ma'ar can talk and Mindspeak himself at the same time.
