"Some people with questionable taste make basement-dwellers to have sex with," says Cam.

"Ewwwwwwwwwwww," says Sable. "Ew ew ew they don't have minds."

"I don't do this!" says Cam. "I'm not even friends with anybody who does it! It's just the most common reason to have them around!"

"Well that's good!" she says. "It's still not much fun to think about!"

"I didn't exactly want to explain!"

"In Hell, where I live when I have not been recently summoned to physics-defying worlds, most demons live on a gigantic plane of solid gold, which is very impractical," he offers.

"...Why?"

"Some demon decided it would be a good idea to have a gigantic plane of gold. So they made one. And it was very big, and more or less in the middle of parts of Hell that demons had previously settled, so it became a pretty obvious place for people who wanted to live in cities to build cities. And new demons tended to appear there once there were population centers, and it's snowballed over time."

"Most of the places anybody lives are covered in less intensely stupid substrates. Soil and lakes and such."

"Well, that's better. ...Can you make local gold, I wonder? It's not quite the same as the gold I knew about before I came here."

"What's different?"

"It can be made into tools that are harder than iron, for one."

"That's... bizarre. I'll go with bizarre. I don't know if I can make it but I can check."

"Try it. It comes in little cubes like the wood, after you mine it," she says.

Cam tries making a cube of local gold.

He makes one of those too.

"Ooh. That'll be useful. Can you make them in bar form, I wonder?"

"Are those a local phenomenon like cubes or do you just mean the shape?"

"Ores can be crafted into bars and bars can be crafted into all sorts of useful things," she says. "They're about as local a phenomenon as the cubes are, I guess."

Cam makes a bar of chlorophyte.

"You're very handy," approves Sable. "Can you just keep making those the rest of the way? Do your demon powers get tired or run out?"

"No, they're pretty unlimited. It would probably be a better idea to make them on the ground in a larger batch when we're wherever you like to store things; I don't have arbitrary carrying capacity."
