"Danger Room?"

"It's a room where we use science illusions to train combat-based applications of our powers, if that's something that interests us."

"Science illusions," giggles Bella. "Sounds fun. I'm not cut out for skirmish myself - I need magic boots just to walk down a hallway without tripping and a good skirmish team has someone to jam my knockout trick."

"Emily likes it more than I do, she's much more suited to running around hitting things than I am."

"I bet she'd cost a lot of points to field in skirmish."

"I don't know how skirmish works, but from context I bet you're right."

Giggle. "I think it costs extra to have a player whose skillset is really off the wall, and someone who controls metal would be that."

"Yeah, it's pretty great. And did I mention she can fly? And take passengers?"

"That would definitely contribute. Of course, if you have too high a point cost you're just kind of out there with four other people fighting forty opposing players, so..."

"My world's cheating?"

"Theoretical noping of our powers."

"Well, even if you went into the world and in local terms your sister counted as a weird elementalist and you counted as a subtle artist, a well-constructed skirmish full army would have a lot of tricks up their sleeves. You'd be jammed and tie up at most three of their guys, and somebody with flying shoes and good stealth would stab her or she'd think she'd blunt-traumaed a guy only to find that he didn't count as 'dead' and still had his sword or an archer with wood arrows that multiply midair would take her out."

"Wood arrows, okay. I'm not saying I'd bet we'd win, but I don't know enough about the system to say we'd lose. Doesn't matter, anyway, I'm not risking potential noping just to play a new game."

"Oh, yeah, definitely don't come to my world."

"I think sometimes Emily has fantasies about being pitted against a vast army of people in metal armor carrying swords and metal shields who haven't got a clue what she is until it's too late."

Bella giggles. "Modern warfare is not quite like that, but she could be a nasty surprise for some people before there were counters invented."

"It's not like that in our world either, although there is still a lot of metal involved."

"Metal's useful stuff."

"It really is, even when two of the people you love most in the world don't have fantastic power over it."

"How does she fly, just wear a lot of metal things and pick herself up by them?"

"Partly that, partly remember how I said our planet was a magnet?"

"Yeah?"

"She's not reliably good enough at this not to have to use the metal bit you guessed, but Dad can just push himself off the Earth's magnetic fields even if he's not wearing a speck of metal on his body."

"Huh. I'm tempted to turn your family into a science fantasy book back home."
