I will try to ensure he doesn't go near anything that's liable to explode if he does collapse while using it, he answers Yfandes.

Then, to Leareth—My house. He gestures straight ahead, to a low, sprawling stone building. The laboratory is built into the hill behind it. However, I think we should rest and resume our experiments in the local morning. It has already been long enough since the Snap that this mission is not time-critical in the sense that is worth sacrificing health for.

He starts walking toward the house, slowly, as though dreading something.

Leareth is kind of suspicious that he's being railroaded into something, here, but resting does seem like the path of greater wisdom. He's also not sure if he should be alarmed by Fëanor's obvious apprehension. It turns out to be impossible to actually muster alarm; now that he's managed to relax, his body is absolutely refusing any of his bids for adrenaline. 

He follows Fëanor, doing his best to keep his eyes open and look awake, though he's not really processing his surroundings. 

Yfandes is also curious what Fëanor is so worried about, and has more energy to spare for it. It's not clear if she'll fit inside the house, but on the way there she makes sure to stay close to Leareth in case he stumbles. 

Shavri is, almost absentmindedly, checking if Doctor Strange's mind-shields on the Elves and Earth humans are still active now that they're on a different planet, and if so, whether there are any new local Elves whose minds she can read. 

She's not even sure why she's bothering, it just seems like it might be useful in general. 

The shields are intact.

Most of the elves down in the village are participating in the singing, which already tends to broadcast their emotional state over a range of several miles even if no one is deliberately trying to read their minds. They're thinking and feeling pretty much what one might expect under the circumstances. The depth of it is inhuman, though; it takes Shavri's breath away. There are also two elves in the house, but their thoughts are tightly guarded.

Fëanor's apprehension is for personal reasons that have nothing to do with anyone else present.

The house is surrounded by a wide, ground-level porch supported by intricately carved columns. There's a red-haired elf sitting in a chair near the front door. If he's surprised to see the visitors, he doesn't show it. His eyes seem to pierce right through Leareth's mental shields.

"She's gone," he tells his father in Quenya. The tone of his voice is utterly flat.

"I—" he begins to reply in the same language, not broadcasting the accompanying thoughts, but the words catch in his throat. "I had hoped to meet her again under better circumstances, anyway. Right now, the world needs saving, and she—last time, she didn't understand that."

A blond-haired elf emerges from the house and embraces his newly-arrived father and brother. Then he sees Yfandes.

You're...not a horse, he says.

:I'm not! I'm a Companion of Valdemar - we're people, just in bodies that look like this: She tilts her head, regards him curiously. :How could you tell so quickly? Most people don't realize at first: 

Leareth is at this point desperately longing to sit down, but it seems rude to steal the red-haired elf's vacated chair, and equally rude to just march inside and lie down on the nearest flat surface before the introductions are complete. 

He doesn't understand the content of their short conversation, of course, but the gist is clear enough; he bows his head. 

I don't know what Valdemar is—I assume that it is not some corruption of 'Valimar' that has occurred during the past six Ages of linguistic chaos, since if you were a Maia that just likes horses I would probably have met you—but I can speak to horses, and your mind is not the mind of a beast. Also, your eyes are too far to the front of your head.

Hopefully we can find suitable accommodations for people of your...shape. We have stables, which are quite well-furnished, but they are still meant for beasts and not for the Children of Eru.

Fëanor leads them all, less Celegorm and Yfandes, into the spacious central hall.

"I have guests who are in need of rest," he tells Maitimo in Quenya. "We will discuss the situation among ourselves once they have been seen to their rooms."

Then he broadcasts his thoughts, gesturing to indicate where things are—Guest rooms are in the west wing. Please do not go in the east wing. I would like to see you try to go in the south wing. Maitimo will help you if you need anything.

Awww. He's so thoughtful. Yfandes likes this Elf already. 

:Honestly, the stables would do just fine - it'd be more suitable for me than what they could set up on Earth! Also, if anyone has time, I could really do with a good brush-down:

Companions, in general, prefer not to have anyone but their Heralds do this, but it's not like that's an option right now. 

Leareth is much too tired to want to investigate forbidden wings anyway. He thanks Fëanor and heads straight for the west wing and flops down onto the first bed in the first room he finds. 

He still expects to find it hard to fall asleep, but in fact he's out within less than a minute. 

Shavri has been sleeping kind of a lot, actually; it's a temporary escape from waking reality. She's not exactly tired, right now. 

:Thank you. I...think I want to go sit outside and listen to the singing for a while, if that's all right?:

Celegorm leads Yfandes to the stables. He has plenty of time to brush her down, if she'd like.

Of course it's alright, he tells Shavri. It changes his meeting plans slightly, but that's okay.

He, Maitimo, and Atarinkë go to his private study in the east wing of the house. He locks the door behind them. The room is warded against eavesdroppers; hopefully that also works against off-world magic as well.

"Where are the others?" he begins.

"Moryo and the twins are in the city. Cáno's down in the village leading the requiem. Turco is, I believe, dealing with the horse-person. And to round it off, Curvo's been with you and I've been here trying to hold this town together in Mother's absence—it's also kind of the only place in Valinor I'm not looked at as though I'm the second coming of Moringotto.

"Now, pray tell—what the fuck is going on?"

"Some purple maniac called Thanos got hold of something called the Infinity Stones that let him kill half of everyone, everywhere. Not the Silmarils, obviously, though that's what both I and Father thought when we first heard the name. He wanted to do it because he thought we'd multiply until we consumed all available resources. Stupid-ass plan, if you ask me, although having ruled a kingdom that included mortals I understand the temptation. We've been helping a group of Men with a random assortment of pseudo-magical special abilities gather the resources to fight him and maybe undo this. The current plan is to try to travel back in time and grab our own set of Stones that way.

"Then, like two days ago, Endórë time, a woman who could fly through space dropped off thirty mortal wizards in a space capsule they'd built themselves with technology worse than what we had during the Exile. I'm not sure how this is supposed to help, but one of them is pretty good at math, and apparently they have some mind-altering magic that might be useful."

Maitimo takes this all in stride. He doesn't really have emotions, these days. But "travel back in time" catches his attention.

"Do you think it's actually possible? To go back, undo something? The way we were taught, in the old days, I wouldn't have thought so."

"The math checks out. Apparently the structure of space-time isn't perfectly smooth at really small scales, and they have some sort of particle that can modify the scale of matter, but they don't have enough because whatever stabilization medium they're using to isolate them is shit and, consequently, one-time use. I'm going to try to use some leftover silma instead; if my assumptions are correct that should give us reusable crystals.

"Now, for the reason I called this meeting: what we—this family—are going to do with the Infinity Stones, once we get them and undo this."

"Destroy them."

"Once I wished I could do the same—no, wished I could want to do the same to the Silmarils. But now that that bond is broken, I do not think it would have been wise."

"We are not going to destroy the Infinity Stones. At least, not until we've used them first."
