"I'm glad. Just let me know when you're done with them."

She plays with them for a few more minutes and then, slightly reluctantly, sets them down. 

And Harry shows them around the rest of campus. Cottage, cottage, classroom building, library, massive combat arena-

"Oh, neat. Any special features?"

"Yeah, it's all hooked up to a virtual reality interface so you can fight full-force without anybody getting injured. It didn't used to be, I had my Combat Finals in the old arena and I broke more than a few bones, but they had healers on standby to fix up anybody who got hurt. Still, it's better to avoid the issue entirely."

"How does the virtual reality model everyone's powers? Is it just that good?"

"It was built by a Devisor, and they don't have to follow the laws of physics. So yes, it's just that good."

"Devisor?"

"-oh, nobody's given you the Powers Theory spiel yet. Devisors make machines that don't function based on the same laws of physics the rest of us use. Avatars channel the power of a spirit, granting them other powers besides that, based on what spirit they access. Espers have various forms of extrasensory perception, like empathy or psychometry. Energizers absorb some form of energy from some source and can release it in some specific form, often either physical speed or energy blasts. Gadgeteers have an instinctual understanding of technology, and can create things far beyond the current cutting edge; technically they're a kind of Esper, because they're easily capable of understanding and improving on devices they've never seen before. Manifestors can create some form of temporary material, like a suit of metallic armor or a geyser of human blood. Mimics can mimic other powers, regenerators can, well, regenerate, shifters can change their shape. Telekinetics have telekinesis, which can be at range or to enhance their own strength, or both. Warpers affect the laws of reality directly in some way, such as by altering probability or by teleporting. Mages have an easier time using some specific form of magic, and psychics have telepathic abilities, often along with telekinesis. There's a class you'll take that'll explain all this in more detail."

"...Mmmmmmost of those we don't really have an equivalent for...but Dr. McCoy could maybe be a Gadgeteer, and...I know of one guy who could be called an Energizer and, uh, he killed my grandmother. In Auschwitz."

"...well, most of them aren't like that, fortunately. Powers aren't very personality-correlated."

"I imagine. He's just...the relevant example, from our world. And I don't feel comfortable even mentioning him without giving context."

"I can understand that."

Harry shows them the rest of the campus. After the arena it's mostly normal, apart from a couple of shooting ranges. They eventually circle back to the Crystal Hall, and Harry shows them into an attached building, which after they go down a few stairs turns out to contain a space about the size of an aircraft hangar, occupied by a massive shopping center.

"You can get anything you need here - I'd recommend getting clothes and toiletries, obviously, plus a cell phone for each of you and anything else you think you'll need. Your ID cards are loaded up with some spending money. A thousand dollars each."

"Whoah. --What's a cell phone."

"It's a phone you can keep in your pocket, and the better versions let you connect to the Internet too. -the Internet is a global network that links all of the computers in the world together, it's kind of like a combination library and public forum, it's really neat."

"The future is neat." 

"I've often thought so!"

Prominently displayed near the front of the store is a display of one-inch marbles of various metals - everything from lead to tin to osmium. "Oh, and the store stocking algorithm has precognition. I always forget about that."

Eeeeee. "Precognition?"

"Sees the future, like some kinds of Esper. It was made by a Devisor. Nobody knows exactly how it works."

"And it has weirdly perfect stock as a result?"

"Yep! Everything from metal marble samplers to, in one memorable case, fifty pounds of dried seaweed, which my protege Ariel saw as it was being purchased."

"Any idea what it was for?"

"Not a clue. Probably a devise of some kind."

"That makes sense." 

"Probably not hypersteel, though."
