This world has a Sun. She has no way of knowing that it is rising for the first time. This world's grasses and shrubs are not universally edible, but the ground is soft, here. There are other people waking.

Oh.

Maybe her world has an afterlife. This is good if it means she gets to see her parents again and terrible if it means she's never going to see her husband again. 

--Is Imliss anywhere nearby?

Yep. She even has the fingers back that had rotted off from frostbite.

Oh, good. Then there can be weeping and clinging.

The other humans are staring curiously at them.

"...Hello?" She says. ...Not in any of the three languages she had known before. She now speaks a fourth language. For some reason.

"Hello!" they agree. 

Okay. "What's your name?" she asks one.

Blink.

Okay then. They have officially exhausted Idaia's knowledge of what to do in this situation. She's just going to hug Imliss until someone attempts to interact with her.

Everybody instead starts wandering around exploring.

Reasonable. The two of them can eventually get up and do that too.

The temperature is pleasant, getting warmer as the Sun rises; the area is hilly. There is a creek. There are occasional patches of trees.

Not the worst afterlife ever, then. Although, uh. Maybe they should figure out clothes at some point.

No one else seems bothered. In the distance there is a lake. Some people seem tempted to walk to the lake.

Lakes contain water which is necessary for survival, so someone probably should at some point. It's not urgent, though.

It is not! The sun is now high in the sky.

It's sort of weird having a sun again.

...So this is not Valinor but are there any edible plants nearby? They should eat.

There are a lot of plants nearby. 

Great. They will identify edible ones and eat them and drink from a creek.

The other humans will mostly follow their lead on this.

Something weird is up with these other humans and it seems to be different from the weird thing that's up with them, if this isn't an afterlife, but there doesn't seem to be a practical way to deal with it. Aside from going on being a good influence, she supposes. 

None of the other humans seem to know each other, for one thing.

Okay, that's maybe sort of weird but she doesn't know anyone but Imliss either.

...Elves just started fully grown. And humans were supposed to start at some point. And all those fucking prophecies had a sun in them.

So if this is that---

Okay which way is west.

This turns out to be surprisingly difficult to determine, unless 'the sun sets in the west' is a safe assumption, in which case it's straightforward.
