Keltham takes a deep breath.
"So, you've now ever been partially exposed to snippets from the basics of the basics of childhood training for dath ilani, you don't have zero idea of how we see reality. We're used to knowing things legibly. Including places where Golarion might have the idea that it's important for people to obscure things, because you've built a weird not-quite-Lawful thing which requires illegibility to work."
"Like - bargaining, the way you first described how somebody would do that for my shirt. You can imagine a non-dath-ilani with a shirt thinking 'oh no, I must conceal that the true value of my shirt to me is just a million gold pieces, if they think it's really five million I can get a higher price, if they know it's one million they can just give me an ultimatum to take one million one hundred thousand take it or leave it. A dath ilani wouldn't be scared of things becoming legible, because they have more Lawful approaches that don't disadvantage them in the presence of that legibility; they know the right thing to do is refuse unfair but mutually beneficial trades with very high probability. The real value they put on their shirt isn't a secret for them the way it's a secret for somebody bargaining the usual way for Golarion."
"I mean, if they were playing by Golarion's rules, they might still try to make the other person think it was five million if that was the game. If it wasn't anything serious like negotiations with Cheliax, I could see myself playing the bargaining game the illegible way if that saved me time explaining things, I'd try to have fun with it even, though I doubt I'd be very good at it on the first try. But I'd have a legible game to fall back on if the illegible game blows up or isn't going my way."
"If you're used to that being the way things are, trying to play an illegible game with no known legible Law underlying it feels like walking on wet ice... you don't have a lot of ice. Feels unstable, like you're about to put your foot down wrong and fall over, any second. As kids they train us to keep going anyways and parse the universe as we run through it, but that doesn't make illegibility feel safe."
"There's places even so where Civilization would - give somebody a hug and tell them it was okay to not be totally legible right away. A mother who just gave birth to a child doesn't need to immediately put a value in unskilled-labor-hours on her baby's life, how much she'd pay to avert a 0.1% chance of various bad things happening, any of that. Anybody who burst in and started quizzing her about that would be ejected from the maternity hospital and probably from most of the cities in Civilization."
"But when Civilization gives someone a hug and tells them it's okay not to make up numbers today, what that relies on, very crucially, is the expectation that the numbers the mom isn't making up and doesn't know to herself are roughly correct numbers in the sense of leading to roughly the same decisions as better numbers would. The reason we give a hug of it's-okay-not-to-be-legible-today to the mom who just gave birth is that, if she did make up numbers about the value of her baby's life to her, they'd be more like four million labor-hours than four labor hours. She's not going to frantically drop her baby in order to save a water-glass from falling and breaking. If you expected her to get decisions like that wrong you'd tell her to make up legible numbers immediately and run them past somebody else."
"Someone tells me that she's given herself to me, to do with as I want, and if I'd grown up in Golarion we'd probably both be fine from there. But in reality, I'm pretty sure there would be some things I could do that were really not what you had in mind, like, like taking that sharp thing... +3 vicious nasty bigsword, and killing you with it, and then after you're brought back I just kill you again and tell Cheliax not to bring you back that time. That is probably really not what you had in mind, and just to be very clear, it is not what I had in mind either. And you can't spell out things like that for me, my model predicts you replying, because then it's you telling me what I can't do, and contrary to the nature of this thing the way it needs to be. In this case there's no problem, right, because it so happens that I don't want to do that to you, my brain is generating the correct answer despite it being illegal to tell me an underlying Law. But that also means I'm playing an illegible game that has no known legible game behind it, and I feel like I'm walking around on wet ice every time I try to think about moving forward with it, because I did not grow up in Golarion, and I am not confident that the numbers I'm not making up are roughly correct ones."
"Done."
