The palace of the Pharaoh of Osirion is not less luxurious than the Palace at Egorian of Cheliax's Infernal Majesty. It is stylistically pretty distinct. 

Osirion has not made a lot of changes to impress Keltham - they're not making errors about the organization of their society on purpose, and if they are making errors, they want him to know about them to help them correct them! But they have ensured that all of the concubines are dressed the same as the male palace staff.

They're not planning to hide that that wasn't how it worked yesterday, just, maybe it'll help get off on the right foot. 

The Palace is mostly full of open, half-overlapping courtyards and balconies. The sky up above is the eerie, magically-lit Dome interior, not the sky. 

There is a small packet of notes for Keltham; each of them includes some money, for his trouble reading them. 

Micropayments!  Keltham is happy for all of 2 rounds before he remembers not to be.

Decor seems very standard, very prosaic.  Sky effect is interesting.

What do the notes say?

Keltham:

We met yesterday; I am Prince Merenre, a sixth-circle priest of Abadar and the pharaoh's primary advisor on economics research and, lately, the Keltham Situation. I'd like to extend an invitation to join me and my wife Ismat, who developed a system for training non-wizards to craft magic items, for breakfast. Today is not particularly better for us than any other day this week.

The next letter inquires as to the intellectual property status of the things Osirion stole from Cheliax through espionage on the Project. All spending and profits related to that are enclosed for his review, and they haven't spread it onwards.

The final letter has a list of all of the Palace servants, concubines, royals, Church operatives, etc. who did not decline to participate and the prices they listed under Fairness this morning for Keltham to grab them in particular for an hour of questions if he happens to want to talk to a not very selected person. There are hundreds of people on it. Many of them listed negative prices because they think Keltham grabbing them in particular would be really cool. 

...feels like the next story-arc of unreality is supposed to be the one where they imitate Civilization and like he's finally home at last, and he has to notice all the smaller notes wrong with that; which will be harder to detect compared to the louder notes in Cheliax, now that he / the reader have been alerted that Conspiracies are a thing.

Who's got the largest negative price?  Keltham is contemplating trying the most predictable action possible, to see what the next layer of Conspiracy prepared for that.

There was probably something clever he was supposed to do to have the character Korva Tallandria with him at this point, who'd be very useful for figuring this out.  Like, not get her almost sent to Hell.  That was probably the flag event he missed.

Largest negative price: seventh circle cleric of Abadar Temos Sevandivasen put 1250gp.

Okay, you know, sure, let's try that one.

Keltham was planning to ask a lot of questions about theology and afterlives anyways.  If there is some kind of bizarre metaliterary mirror-universe business going on, he'd like to know about that part immediately, actually.

How does this guy feel about breakfast, and then maybe helping Keltham spend a bunch of time in a library trying to figure out what's up with the universe?  It can go on longer than one hour to make up for any time Keltham spends eating or reading instead of just asking questions directly.

He is willing to do that though he actually just arrived in Sothis last night so he isn't an expert on the palace library. 

Well, does he have a negative price for a quarter-hour, then?  Keltham does need somebody who knows the palace library well, he's pretty sure, but Keltham doesn't want to miss whatever it is he's supposed to find out here.  So maybe just breakfast.

...Keltham realizes he's making an expression he copied off Carissa, and wipes it off his face.

Sure! 500 for a quarter-hour.

They can have breakfast brought up to a table on one of the balconies overlooking one of the courtyards. Temos Sevandivasen looks exactly like the fake-priest of fake-Abadar Keltham met yesterday.

"So, you look exactly like - somebody with a very similar but not identical name - that I saw in a scry of Absalom yesterday.  I'm actually going to just say this out loud, because if it crashes local reality I think I'd actually be happy with that outcome."

"I generally work from Absalom; I came to Sothis yesterday afternoon following a suspicious interaction with a Chelish agent. Our best guess is that they intended to use a real conversation between the agent and myself to get information to feed you, and then they had to alter their plan on the fly when I refused them, but you probably know much more about that than we do; it's indeed why I was so desperately curious to meet you."

How totally logical!

...Keltham actually does remember, then, something about Carissa saying yesterday that she used the Queen's overpriced headband to make up an entire theology.  Which, sure, very legitimate rationalization for this, in retrospect.  Maybe the point of this part is to raise his alarm level and then defuse it with a totally logical explanation.  That's to signal to the reader that most things about the pseudo-Civilization will seem to make sense at first and won't just have outright transparent flaws on day one.

"Well, they got your appearance off the brief encounter, and then I had a long conversation with, I think, actually, my girlfriend, and her version of Abadarian theology which was basically that Abadar was about running business concerns.  I assigned her a research-level math problem to do while 'we' were talking, and at one point also tickled her, because I was suspicious that what 'you' were saying was something she could fake, but she was apparently wearing the Crown of Infernal Something Something at the time and was able to juggle all of that simultaneously."

"You should send her a bill for using your name and likeness.  I'm genuinely curious about whether she'd pay it."

" - I'll try, if no one can think of a reason that's a terrible idea. I'm not sure just from the description 'running business concerns' whether it's something where there's genuine Abadaran theology or not? From my own background I'm much more concerned with the applications to governance but there are merchants who've made progress on theology related to running a business that captures wealth in an Abadaran fashion and not through coercion or deception or things that end up amounting to it."

"I was trying to verify that I was talking to a genuine priest of Abadar - who I did not know at the time was" supposedly "my god, and that you were hearing my actual questions, and responding to those in ways that only a priest of Abadar should've been able to do.  Except that their version of Abadar was supposedly just about, economics, supply-demand stuff.  So, for example, after I asked 'you' about women not being able to own property in Osirion, and 'you' said that women had relatively more rights after Abadar took over and Osirion was slowly moving in a generally Chelish direction there, I asked 'you' to say something economics about that.  'You' gave an extended analysis of how different combat rules in Avistan had resulted in fewer men, an oversupply of women, and that had invalidated mating strategies where women held out for marriage."

Temos isn't very readable, but in a different way than Chelish people; it's like he's very deliberate about the steps between hearing something and deciding how he feels about it, so his response is faster than the eventual arrival of his face at a trouble expression. "There might be something to that. Nonetheless I find myself objecting that it's not the answer any true priest of Abadar would have given you; it is too purely descriptive, and we would struggle to refrain from referring you to a dozen different papers about theoretical models of filial piety, in the course of trying to give you a proper answer."

"What's the actual situation there, relatively briefly?  I've got - a number of high-level questions and should go through them breadth-first before going deep on any of them."

"About Osirion and sexism? Osirion is unpleasantly sexist, the Church less so than nearly every other social institution in it but still enough to appall you, probably, if you're accustomed to places that treat men and women no differently. I wouldn't raise a family here, wouldn't really even live here. I don't have a fundamental values disagreement with my colleagues in the Osirian church, I don't think, we just have very different instincts on some questions that are hard to answer."

"Have to say, if the representation I got of Osirion was basically true - that women can't own property - among my first instinctive reactions there would be to tell them I'll only be teaching Osirian women, so as not to distract the men from their important work of owning property and being allowed to participate in the economy."

"I might be misunderstanding what you'd hope to accomplish by that but I don't think it'd work. Among other obstacles, women in Osirion overwhelmingly cannot read or write, and that is in fact the main sense in which it's true they can't own property; the sort of educated woman with independent means of support or a supportive husband who'd be able to attend your classes also is able to meaningfully participate in the economy in every other way."
