:Yes, let's. Nayoki's not hurt but she's going to want a quiet place to rest, she did a lot of magic: 

Nerdanel goes to put Macalaurë in his crib, then locates beds for Vanyel, Leareth, and Nayoki.

Now that Leareth is relatively stable and no longer requires the suit to levitate, Tony takes it off him.

Fëanor continues to interrogate Tony about physics and engineering.

Thor rescues Tony with an interruption.

"So what's the plan here, are we waiting on the wizards to wake up?"

"Wait—how do you speak Quenya?"

"Translation magic. I'll explain it later."

"We need to make a second pass at the Time Stone. Unfortunately I don't know anything about its history, except that the founder of Strange's order of wizards discovered it thousands of years ago—well, before our time—and it's been with them ever since. I want to get it from slightly before then, while it's unguarded. Problem is, we can't really look up history here, since I'm pretty sure none of it has happened yet."

"So you're saying we should go back to the future. Er, the present."

"Yeah. Actually—ask Fëanor if he knows an Agamotto. Maybe he was an elf, wouldn't surprise me."

Thor relays the question using Allspeak.

Nope. Never heard of him. What does that name even mean—it's not Quenya—

Tony has, of course, no idea.

They go back to 2018 and ask present-day Fëanor the same question.

"Nope, no idea. You could probably look him up, though—most of our libraries are digitally indexed, now—"

He goes to the computer terminal and performs a search.

"Agamotto," he reads. "Local name of the Blue Wizard Pallando, one of the five Istari sent to Middle-earth in the Third Age to aid in the war against Sauron. Known to have abandoned the war early and founded a cult of magic in the East. Fate unknown."

"Wait—Strange's magic order was founded by Gandalf's cousin?"

"Apparently. How are things going in the Years of the Trees?"

"We met past you, he's very excited by our tech. Wizards are still unconscious or nearly so. We're kind of waiting for them to recover—we need one for this mission and another to get to work on long-distance portals."

They go back to the Years of the Trees and wait for a wizard to wake up.

Leareth is going to be deeply unconscious for the next twelve hours, local time, and even when he does start to wake up he's not especially lucid. He keeps trying to ask the Healers something about shields. In Kaled'a'in. Which they don't speak. 

Vanyel, however, gets a solid "night's" sleep - it seems like it never gets DARK here, it's terrible, but he can manage by burrowing under the covers of the bed they've offered him - and then he feels mostly fine.

He gets up, still squinting at the sheer amount of light, and starts wandering around looking for something to eat, somewhere to take a bath, and someone to talk to about the next steps of their mission, ideally in that order. 

This is (a) Fëanor's house, in (b) a time without a clear day/night cycle, so regular mealtimes aren't really a thing. But he runs into Nerdanel, who can show him where the kitchen is and help him make some breakfast, and also osanwë-yell at her husband to start heating some water because Vanyel wants to take a bath. In Tirion there's a central boiler system for the whole city, but this house only has cold-water plumbing—it would be wasteful to heat water continuously in this warm climate.

When he's done with his bath, he can find Tony to explain the next steps.

"We've mostly figured out where we want to make a second pass at the time stone. There are going to be more wizards involved, and probably a language barrier that requires telepathy, so you'd be really helpful, if you're up to it."

:- Oh, right. Of course I'm up for helping. If we don't expect a huge fight, I'm all right now - I guess I might not be at my best yet, if we do expect a huge fight: 

"Not expecting a fight, barring Thanos somehow managing to find us, which I think is much less likely this time. You able to do portals, though? Those seem to be much more tiring for your people than they are for Strange, for some reason."

:I think it's because he gets all his power through that magic artifact, the ring he has. For us, it either comes from our own bodies, or from nodes, if those are around - and even then we still have to channel it through ourselves, so even then it's some amount tiring. - Um, and I'm - not very good at Gates right now. I was...badly injured, in a magical accident, almost a year ago - I think being dead and coming back fixed all the physical damage but I'm a bit...off-balance. If I could have a day - and an energy source - to just practice a lot, I'd be more confident about it: 

He frowns for a moment. :...I think the Silmaril might work. As an energy source, I mean: 

"Mostly the problem is that Thor and I can both fly and you'll need to move equally quickly. I can let you borrow a spare one of my suits, though, or you can practice for a while with the Silmaril. Or both. We have as long as we need."
