They'll start exploring in a more westerly direction for the moment. They can make a concerted effort to get back to the others when they have their bearings better.

If they wander westerly for a while they will reach a desert.

...

They're going to wander right back over to the other humans for now. And consider how to get through--or better yet around--the desert.

The other humans have found some soft patches of ground to sleep on, and are sitting around describing the things in front of them, rather idly.

Soft patches of ground are not exactly ideal but it's warm here so who the fuck cares.

And eating plants is all very well and good but are there huntable animals around, meat is good and also skins are good for things like clothing and carrying water across a desert if it comes down to it.

There are animals around. No one present has the faintest idea how one would catch one.

She doesn't really feel like trying to explain the complexity that is Her Life So Far so she's going to pretend to invent the bow and arrow instead of admitting she knows how to make them already.

...Or she would if she had anything to fletch arrows with or make a bowstring out of. Hmm, snares have the same problem as bowstrings...what kind of animals are present?

There are rabbits. There are geese. Just before sunrise there are deer who come to drink from the lake.

Yeah she's not fucking with geese up close and personal. The rabbits haven't learned to be scared of people yet, though, have they?

No, but they're scared of most things without needing to learn to be.

Ugh.

After a few fruitless hours spent attempting to capture lagomorphs with her bare hands she starts experimenting with grasses to see if she can turn any of them into anything remotely resembling string.

There's straw! People used to weave straw! Probably not into string, though.

Oh, straw! She knows how to weave straw! She made a hat out of straw once and then put incredibly garish wax fruits on it! She can make a basket out of straw and attempt to trap rabbits with it.

It works slightly better than trying with her bare hands! After a day of trying she gets a fluffy, bewildered rabbit.

Poor thing. But she spent a gloriously happy month living off of random plants and game and is rather inured to the charm of fluffy things as regards not killing them. She makes it quick and painless.

Everyone else is kind of staring.

She's going to act like this is perfectly normal because they proooobably don't know any better. Right? ...She is less neat than she could possibly be in getting the skin off and roasting it. Fire: A Thing. Neat, huh?

Weird. 

They stare, a bit.

Some of them come over and try to touch it.

Idaia can't think of a better way to demonstrate that this is a bad idea without admitting that she knows this already than doing it herself. Luckily she knows things about fire and can get it close enough to be demonstrative without seriously hurting herself.

Some of the humans are persuaded. Some try it themselves.

Around midnight glowing, shifting mist-figures rise out of the lake.

This is alarming!

Everyone is alarmed!

They don't do anything; there's a splash on the far side of the lake and they head towards it, getting less and less glowy until they are impossible to see.

Everyone is very alarmed.

Idaia would totally abandon her not-admitting-things policy to warn people about this if she knew what it was to warn people about! She does not. "Probably a Maia or something" doesn't really count, they're too varied.

They could check out the other side of the lake once it's daylight an less likely to be inhabited by spooky things. Probably less likely to be inhabited by spooky things.
