"Awww, tiny baby pre-space-travel world," Dion coos. He's clearly teasing, but also genuinely seems to think Val's world is adorable. "You'll get there. Right, so, lightsaber—" 

He starts disassembling his lightsaber with the Force, partly to show off and partly because it's faster. The pieces float in the air like an exploded diagram of a 'saber's inner workings. 

"You're good at that, that's a lot of little things to control at once."

But normal good at it, he's ever in his life seen people that good. And Dion might have practiced doing this specific thing a few times.

"Yeah, I couldn't do it if I didn't know this thing like the back of my hand. Probably better, actually, I didn't build my hand."

Time to explain the important features of his lightsaber. Lightsaber: when activated, emits a two-foot-long plasma beam, contained in a blade shape by magnets, which can cut through just about anything and also deflect or block projectiles. Parts that need to be able to move are these and these and these; parts that probably shouldn't be messed with include the power pack and this tiny crystal floating right in the middle. 

"I've never seen anything like that - you don't have to personally contain the plasma? How does it generate it?"

Complicated technobabble explanations! The tiny crystal is apparently an integral part of the mechanism despite not being noticeably connected to anything. 

"So what sorta wards could you put on this thing? You probably don't wanna do, like, all the little pieces, but you could ward the casing?" 

"I could! I can make it immune to magic or immune to magic besides yours. I can ward it against extreme temperatures, but if it lets you hold plasma in your hand already that's probably redundant. I can keep the case from breaking or something, too. I'm not clear on what lightsabers are usually damaged by, though, so I don't know what would be the most useful for you."

"You probably couldn't make it watertight and leave it working...making the case unbreakable sounds really useful! Most of the time when lightsabers break it's 'cause the casing got beat up," he explains.

"So does warding it against other people's magic...but I'm guessing you'd need to do that one last. I think it's probably fine with heat but making it not get too cold would be nice?" 

"I can do all those things! I think the information you've been giving me is worth one of them, got anything to trade me for the other two?"

"Uh...not really? Jedi aren't supposed to have, like, stuff." He deflates slightly.

"You could just make it unbreakable?"

"I could but I'm just as interested in information as stuff right now and I'm sure you know other things I don't."

Dion perks right back up again. "Oh, sure! So what d'you wanna know, should I just give you a crash course on scientific advances more recent than spaceflight...?"

 He pauses and spends a second or two in an internal debate. 

"Aaaaand my ethics teacher would yell at me if I didn't tell you this, so...Bar will give out books on that stuff. She doesn't even charge unless you wanna take them away with you." 

"Oh, thanks! Maybe you can help me figure out what books to ask for. Space travel is cool but maybe you have other technology we don't, too?"

"Sure! Do you have, uh...comlinks? Holograms? Droids? Cybernetics? Tissue cloning? Repulsion coils?" 

"We have ways of getting sound and pictures from far away but if you don't have most kinds of mages then I think you must be doing that a different way. I don't think we have any of those other things."

"...you use magic for a lot of things we do with technology, huh. Guess that makes sense if you have more mages per population than we have Jedi, and they can do more types of things." 

"...Mages per population?"

"Yeah, like, Jedi are one in...a trillion? I think it's a trillion. But it sounds like you have way more mages than that." 

"No, we only have people. What are the other, uh, what else are you counting when you say Jedi are one in a trillion?"

"The...rest of the sentient population? A lot of the galaxy is humans like me—and I'm guessing you as well—but not all, there's hundreds of intelligent species." 

"But... so are all the humans Jedi?"

Dion is looking increasingly confused.

"...no? There's some species like that—Neti, and I think Miraluka and a couple others? Humans are higher than the galactic average for Force-sensitives but not that high, more like one in ten billion or something." 

"But what are the other humans? They're just - empty? Fake?"

"That's kinda rude. I mean, some Jedi think that about non-sensitives, but you're not supposed to say it."

He takes a moment to get the implications. "So does your world just not have non-sensitives? People who aren't mages, I mean." 

"Of course not. For any given type of mage, most people aren't, but everyone has some kind of magic, otherwise they wouldn't be people and that's horrifying. Why - why would it be rude, why would it matter if you're rude to animals, do you need to move to a world without fake people?"
