"No, I don't know where any of these planets are."

"Hell is technically a plane not a planet. The difference is that no amount of travel would get you there. We go there when we die, but I don't think people from where you are go there when they die or I'd have heard about that."

"That sounds... imaginary," he tells her, though he's not sure it's really kinder to tell her than to let her go on believing that.

"I am not sure what you mean by that. Planes sound imaginary? Specifically Hell?"

"Planes sound fairly imaginary but mostly going somewhere when you die."

"Do you just not go anywhere when you die? You...all turn into ghosts?"

"Ghosts are also imaginary."

"Then...what happens to your soul when you die. Does it just - immediately get eaten or something."

"...Souls are imaginary."

"...okay, then how does resurrecting people without a body work, and why, if you've cast Trap the Soul on them, is it impossible to resurrect them until you've smashed the gem that you in the conventional parlace 'trapped their soul' in."

"I do not think I am on enough drugs to be convinced that you can resurrect people."

"- right, sorry, I forgot you don't have divine casters - you can actually do it with a Wish too but I don't know that people would've been confident they had a safe wording, if there were no divine magic - you are not on any drugs, I don't think, and I don't see how that'd cause me to be claiming to you that we can resurrect people while you disbelieve me, drugs don't do that."

"Magic is imaginary."

She does some dancing lights. 

"I don't know how you did that but I'm still pretty sure it wasn't magic."

"Wanna go watch people fight demons?"

"I had a concussion last time but I remember swords."

"The fighters use swords and the wizards cast fireballs or blind people or whatever but they mostly save them for when they'll do the most, since you can do swords all day and you can't do fireballs all day."

This is all extremely imaginary and he has no idea what the point is! Are... Numerians with high tech... infiltrating the superstitious barbarians... with technology they're passing off as magic... to keep the demon population down, or spy on people or...

She Detects Thoughts when he doesn't say anything but it's not very illustrative. "Is there something that would convince you that there was magic."

"I never really thought about that before."

"I guess you can be skeptical about magic if you want to. How do people sail their space ships without magic?"

Uhhh what's common knowledge that it won't be a huge betrayal to say. "They need a lot of electrical generation capacity, same as what charges the gun, and in-system propulsion is different from what jumps between stars -" And he can explain in the loosest possible terms what the deal is there.

"Electrical generation? Do you know how that works?"

"There are a lot of ways to do it. I don't know how to build a modern reactor from scratch."
