"What happens?"

"It basically fails to respond."

"Well, that's disappointing of it."

"I'm not really sure it's a person."

"Was it made by sorcerers too?"

"No one knows exactly what it is or where it came from, but maybe."

"Is it new enough that 'it's always been around' is not a candidate?"

"I think the first recorded magical girl activated twenty-seven years ago."

"Wow, that's really recent. How many are there now?"

"About fifty million?"

"Worldwide?"

"Yeah."

"...what's this world's population?"

"Something like seven billion?"

"Mine's lower but on track to be there in a few decades."

"You're a couple decades behind us, technologically, so that makes sense."

"Yep! I wonder if we specialized differently enough to be ahead of you on anything."

"Oooh we should see if we can find out!"

"First place to look would be anything that's mostly handled with magic here. Basically nothing is mostly handled with magic in my world."

"Hmm...light pollution is the first thing that comes to mind..."

"We kind of just have that rather than handling it. You handle it?"

"Yeah, cities have wards over 'em."

"Cool." Not that she will be able to get a good look at the stars thusly revealed.

That's a shame. Maybe she can get a spell for that.

"Why is light pollution enough of a priority to ward all the cities, or is it just really easy to do and doesn't have any side effects anyone cares about?"
