"Secret for now."

"So you have... secret intelligence... suggesting some things about this planet's magic. And in exchange for... unlimited wishes... you want to provide..."

"The ability to power magic without grief seeds."

"And with, instead, alien technology you will provide but not explain?"

"I intend to explain in enough detail that you could reproduce it."

"I suppose that's good... but you won't tell us where it came from, so we will have no idea if it's, say, under patent, or has side effects and is meant to come with a warning label..."

"I actually intend to explain a lot more later. But explaining technology is halfway to handing it over, so I’m not saying much yet."

"That might make the most sense of any of the choices of omissions. But you could demonstrate by brightening somebody's soul gem?"

"Yes."

"I'll... see if one of my magical girl friends are available." He pulls out his phone.

"Sure. You want your friend to come here or what?"

"Yeah, here is good."

"Okay." She'll just wait for an update on the magical friend.

In comes a magical girl in fawn and dark green and gold. "You can undim gems?" she asks in tones of mild skeptical interest.

"Yes, I can. My setup's kind of fiddly to arrange since it has to vary depending on the room and the people in it, and it will work by making you happy, which I'm told is something some people find philosophically objectionable. Are you interested in trying it?"

"People... philosophically object to being happy?"

Shrug. "There are some strange aliens out there but I think it’s more that they dislike it when things cause their feelings to change in a way that doesn’t feel natural? If looking at weird tech wouldn’t usually make them happy then it’s uncomfortable if it does this time?"

"I'm okay with being happy. Philosophically."

She’ll arrange several objects with an assortment of lights and twiddle some dials and ask that they keep any phones a couple feet from this central one and that the magical girl stand here...

"What's it do to phones?"

"Information useful for reverse-engineering the device will be provided if we come to a satisfactory agreement. If you follow instructions, your phone will not be in any unusual danger."

"Okay but like, is this radioactive or something?"

"No - uh, yes, I saw a comic explaining that all materials are radioactive - uh, actually I don't know if this is even as radioactive as the average banana. I would need to ask the manufacturer. The question is whether it's as radioactive as the average banana, though, not whether it's as radioactive as an atom bomb."

"...okay." They set their phones aside.

And Relu sets everything up and turns it on. Fake indicator lights flash. There is a noise. (The microphones in the room benefit from some behind-the-scenes coordination between Relu and Inanna and some active noise canceling. Hopefully it'll be enough.)

Relu, of course, is delighted.
