She waits for indication of whether she should sit down, or sit on the floor, or stay standing, or be restrained to something, or something else.

That is an interesting type of world. (Jewel will likely be excited, if Xeyr lives long enough for her to get here.) If no one seems to be minding, she'll look around and out the windows and at any book titles she can see.

"You can sit," the Captain says. "I want you off my ship but that's no reason to be mean about it. Sanha, go relieve Carl. Galen, watch her, stay diligent, give a shout if she tries anything. I'll have Willis make up a castaway's crate and go back to the bridge. Nice and neat."

The tense woman nods sharply, a little sullenly, glaring at Xeyr. "...Aye, sir." The big guy holding a gun just nods.

The captain leaves.

"Thank you." She sits, and does not try anything.

In about an hour, the ship turns and descends slightly. There's a large - floating island? - visible outside the lounge windows. There are trees and birds and alien things visible. There don't seem to be any people.

Some other sailor comes by with a wooden crate full of dry food and four full canteens and a big white cloth sheet. They lead her to a sort of elevator as the ship maneuvers to try and stay steady over the island. "Down you go, miss."

"Thank you. I hope your travels go well." She goes.

"Likewise." He pulls a lever and the elevator starts to descend. It touches down on the island with only a little bit of a jarring impact.

(She doesn't seem too worried about being stranded on an empty island. So she probably does have a crew coming after her with some kind of radio nonsense, or something. Good riddance.)

"Please don't worry about me or feel you've done wrong by me or feel guilt on my behalf. You've been very kind, and I will be well." (It's true, even if this will be a time it takes Mia a while to come to her. Being on an island is not a bad temporary fate, as they go. And if not well here, she will be well somewhere, however short or long away.)

When it has descended, if it seems like she is supposed to get off the elevator, she does that. And brings anything that was put down with her.

The elevator goes back up. The aitship's engines rev and the backwash ruffles her hair a bit as giant propellers pass overhead.

Now she has a wooden crate, a big piece of white cloth, some food and water, and a smallish floating island to explore.

She looks at what the ship is like from outside, while it is still here.

It's pretty big. The lower section is hundreds of feet long and maybe eighty feet across, and the large balloon section is proportionally larger. Though the lift section might be smaller than one would expect of such an airship, compared to one that exists on Earth.

There are four large engine nacelles with propellers sticking out a bit from near the rear of the ship, and there are giant rudders and ailerons you could fit a house on. There are only a few windows. It looks to be made mostly out of wood and canvas, flimsy in the way that airships tend to be, though there's some metallic equipment here and there.

Earth is not her own reference. She's seen a lot of sorts. People craft so many things in so many places and ways...

She looks what food she has, and explores the island.

Dried fruit. Biscuits. Hard bread. A little bit of jerky and something like trail mix. All told, maybe a week's worth of food for one person. But she'll run out of water in a couple of days unless it rains.

The island is made of some strange coral-like rock, tiny thin-walled cells that are very delicate alone but surprisingly tough packed together, covered by a layer of dirt thinner and thicker in some places and then by a lot of Earthly and otherworldly plants. There's some tall grass with floaty seeds, bushes and shrubs, an alien plant with thick, waxy leaves like palm fronds, some trees. There are few insects - these tiny barnacle-jellyfish things seem to have out-competed them. There are a few squirrels, some birds, and a small colony of manta-ray-shaped floating critters resting on a sort of mangrove clinging to the side of the island.

In terms of forage there are some unfamiliar maybe-poisonous berry bushes, and wild onions, if she recognizes wild onions.

An interesting world. 

The berries are unlikely to be poisonous to her. She has too much variety of experience to be sure of the onions, rather than too little to recognize them, but she checks out various plants and discovers them successfully. 

She tries some onions and berries (spaced), in case they do something she is not expecting.

Does she have anything she could collect water in, if it does rain?

The berries aren't poisonous. The crate probably isn't waterproof. The big sailcloth could get nice and soaked at least until it dries, and maybe be used to refill the plastic canteens.

Is the food also inside something waterproof, or should she attempt to arrange protection from water for it? 

She finds a good location for the sailcloth for that eventuality. 

The food is wrapped in a mix of paper and plastic bags. She might want to eat the paper-wrapped ones first.

In the distance there's a - squeal. It looks like a flock of birds are pecking apart some unfortunate flying critter. They rest on it, dragging it down and eating voraciously, until it gets too low and then take flight again.

She consolidates food that can be stored in plastic bags into those as possible, and tries some waterproofing with the waxy leaves.

Oh dear. What happens to the critter? Do the birds look likely to attack island-bound persons?

Critter's definitely dead! There's blood and everything! It was about the size of a big raccoon or a medium-sized dog. It's plausible that the bird swarm would be wary of larger prey.

OK. 

She makes a plan for the food and water. She begins further exploring the plants. Can she weave the tall grass? Could she potentially spin the fibers of the floaty seeds? Can she make anything with the waxy leaves? Does any other vegetation seen usable for that kind of work? Does any of it look like it would have potential if dried?

Also, what color are the berries?

The tall grass is mostly dry and fragile. The trees seem healthy, if a bit - thin? There's loose sticks here and there. The floaty seeds aren't very fibrous. She can catch a seed easily, but it's a paper-thin shell that weighs almost nothing. The floaty critters seem to enjoy eating them whole, though. The waxy palm-frond-ish leaves would take well to being woven into things, they're relatively thin and flat, tough and flexible. There are fluffy tassels on the edge of some kind of mangrove thing that might turn out to be spinnable fibers - or hold some water.. The berries are dull red. They don't seem to be poisonous, upon testing, but they don't taste very nice either. Kind of starchy and hard.

Can she eat the floaty seeds? Did any of the people she saw have hair that color or close to it?

She hangs up some picked waxy leaves to dry, to see what they will be like then. 

The floaty seeds taste like inedible dry grass.

The hair colors she has seen are various shades of brown, grey/white, black, and blonde.

Hm. Is any of the dried fruit a local-hair-like color or close?

Some of the dried fruit is pale enough to probably pass for blonde.

Not her choice of color, but it is better than to alarm people. She holds it in her hands and squeezes. The new color creeps through her hair from the roots until it has all changed.

She starts weaving a test square from the waxy leaves.
