"Mmm not bad," Jack said, mock appraising. "In fact it's actually quite sexy when you do that. You should do it more often."

He let out a slight laugh and looked back to the water and then again to the Doctor. It looked calm from here, and what had been so obvious up close was barely a shimmer on the surface.

"It's not always doom and gloom, Doctor, sometimes it's just this. They're not afraid. Not of anything here, at least. Boeshane is safe, at least now. They're just inside because that's the way of the city, and fine there are some jackals that come out after dark. Now there might be the odd trader boat out, sure, but they should have all birthed up by now. And I don't see anything out there, do you?"

As they reached the city it was more obvious that it was contained. The large mass of zig zag buildings were actually even bigger than they looked from a distance, and they formed a surrounding wall with the majority of the city within it, like a huge atrium. Ahead there were gates and they'd have to pass those before they could get in at all.

"Psychic paper," Jack said to the Doctor. "You'll need it."
