It's much less scary when you know that's a person!

They fly back to camp.

They go almost all the way around the island-- maybe a mile or two. Iskierka and Kulingile fly low above the jungle, not as high as the mountain in the center of the island. There is no other land in sight on the horizon, even from the air. Only ocean stretches off to the sky.

They land at a camp on the beach, made up of around thirty men in various states of bedragglement and of various ages-- though if he looks closely, he may notice that one of them is actually a teenage girl dressed the same as all the military men, practicing fencing with one of the teenage boys. There's also a small tent near their fire pit. 

A few of the men are wearing green coats like Granby's.

There is also another dragon lying on the beach. He is a bit larger than Iskierka but not as long (so about the size of a house), black and glossy with horns and a webbed ruff.

Kulingile lands near the other dragon. The green-coated men and a few others drop what they're doing to come greet them.

"Ho, the camp! Look what we found!" Granby hops off of Iskierka, gesturing at Harry to come with him.

"Not fresh water, I take it."

"No. This is Ensign Harry Kim. Says he's from the future. ... He has something that can make the hottest fire I've seen, I think. Melted sand into glass right in front of our eyes."

Iskierka scoffs angrily and jets extra steam. "I am sure that I can do hotter."

Laurence turns to Harry. "Pleased to make your acquaintance." He's not sure he means it. "William Laurence, of Temeraire. And I see you've met Captain Demane and Kulingile as well." He emphasizes Demane's title a little for the benefit of those around them.

"Nice to meet you."

To Granby: "I'm pretty sure I'm not from your future, actually. There weren't any Dragons on my Earth in the 1800s."

"No dragons! How terrible! Much better that you came here," Iskierka opines.

"Would you perhaps be willing to demonstrate this ... sand-melting device again?"

"No problem."

He melts more sand!

Well. ... He can't actually think of a way that that's helpful right now but it is impressive.

"Well. As you may be aware, we were recently marooned on this island with no recourse but to wait for the enemy ship we surrendered to. They gave us their word that they'd return, and supplies, but we have no particular guarantee about how long they will be in returning and the supplies they left us with are less generous than we might prefer.

"But if you are willing to put in your share of labor to assist us, you are welcome to a share of what we have."

One of the sailors nearby spits on the ground in disgust.

"Of course it would be better for us to find a way to escape the island and get to the Sapa Inca directly," puts in the large black dragon.

Hmm. How many of them are there?

Around thirty men (mostly) and three dragons bigger than his shuttle.

They could easily evacuate the humans by shuttle. 5 or 6 trips maybe?

The dragons are a problem. Harry doesn't know much about Dragon logistics.

"Well, if we fixed the shuttle we could take the humans, of course. I assume the Dragons can't fly far enough, or you'd have left already. How far is it to the nearest land anyway?"

"I don't know. The dragons can fly a hundred or perhaps two hundred miles without stopping if they must, but we cannot risk flying so far over the ocean when there might be no land for much further than that; nor do we have any notion of the mainland's direction. We are not within easy distance, which is all we may safely establish."

"Your ship can fly??"

Weird question.

Oh wait, probably they mean, "can fly in atmosphere". Most spaceships can't.

"Yep! It's just a shuttle so it's designed for atmospheric flight."

"Amazing!! How does it work??"

"I am quite sure we could fly to shore without any such thing, if only we had some notion where we are," grumbles Iskierka.
