Nothing you wrote applies to what I wrote. First of all, IIRC the Priestess mentions that he has already fathered children with them, it doesn't matter if that PARTICULAR one is his.
Second, my comment was about not burdening Zahra with too many children to raise by herself while he was out establishing his reputation as a stalker as a reason to only have two kids. My comment "Also, while he has done well for himself, he wasn't rich like Omar when younger and could afford servants." is referring to when he were younger and not as well off as he is now so what he can afford now is irrelevant. Which why he can take in "strays", as you call them, because he has accummulated some wealth. Plus, depending on how you play the MC you can start to impregnate household members which is another sign that finances would be a limiting factor with not having more offspring over the years.
Thirdly, since his compound is outside Zeta it it would be safe to assume within the context of the story it was probably deserted and run down so his money would have gone to renovation and expansion and not buying slaves or hiring servants, another reason to not have too many children.
So, there are many "real life" reasons why he didn't have a dozen squalling children and it wouldn't be out of place to limit it to two.
It does not actually say that he definitely had impregnated any priestesses only that he very strongly BELIEVED that he had knocked up that one. He had been set up as a partner with that one Priestess before, but the fact he says "believe" instead of "is" what he actually replies to Kateryna suggests that there MAY be a few guys who got a crack at her before him. It also specifically does NOT say he had any other children with the priestesses, only that THAT Priestess had had 32 prior children successfully, but it doesn't indicate ANY of them were his. I mean, some MIGHT have been, but we don't know
Talia claimed to have had six kids with him and gave them to the temple but we don't actually know for certain that they were his since she supposedly fvcked every guy in sight, or at least that's what the queen says.
His finances at the beginning are debatable and yes he does indicate that he doesn't have servants normally but Zahra likes doing homebody work, and he's also had 20 years to make his fortune and he started out with a bang having two kids right then and there and was able to afford them, so the odds are his finances weren't particularly bad over the last 10 years and he probably could have afforded more kids, unless his finances VERY recently made a very large upturn, which we don't have told to us at all.
The game is conveniently vague on money matters, excepting that he always seems to have more than enough when he needs it, and discussions in the past between Rabiah and Zahra suggested that stalkers do make good pay: it's just dangerous work that often takes them away from home for days .
Omar being richer is definitely a fact, and seems to be a matter of disdain for MC. Omar breaks the cultural code we read about in the library, in that he OPENLY DISPLAYS his wealth, effectively rubbing it in everyone's faces, which is something you're NOT supposed to do. I get the distinct impression MC believes Omar is one of those people who knows the cost of everything but the value of nothing. Note that Omar has a ton of money but still doesn't spend on servants, despite this DIRECTLY pissing off his wife, so Omar cannot be used as a yardstick for economic or cultural normalcy.
Last I checked, there's NOTHING at all to indicate that the compound MC's in was abandoned: that would just be making up a claim because it's convenient for your argument. If I'm wrong about that and you can find evidence in a text that he says it was abandoned then I apologize but I'm pretty sure it's never stated or even suggested.
We have to assume that that's not inherently the case it was abandoned, especially considering it's a fairly developed compound that appears to be in good repair, and is WITHIN RELATIVELY CLOSE PROTECTIVE DISTANCE OF THE CITY( not subject to raiders, decayed, etc) which would mean it could easily have a decent property value, although we don't know THAT for sure, either.
And, yes, you can start to impregnate family members, except that, IIRC, it's never specifically mentioned that you can impregnate ZAHRA, only that you can come in her. At least not that I've seen within the text, and I went looking. Insemination does not inherently equal impregnation.
The game makes a bit of a big deal IIRC, that Ain is just now of legal age, so getting her knocked up earlier would have been a no no.
Shani still resists getting knocked up because she's to be a stalker, so the potential of not getting her pregnant is critical for that reason, though she may well change her mind, givien hints in the text.
Emelia was a recent gift from the queen so was unavailable before then.
Fairy was found recently, on the fuel trip to Cairo: she is either a gift from those two decayed (if you didn't kill them earlier at which point you don't get elf Ivy/Yuna, because she got her head blown off by the shotgun collar and then she got eaten) or was a purchase (SPECIFICALLY TO SAVE HER LIFE, although you might also be buying her because she's hot) while on that trip (if you had killed the two Decayed to save the elf at which point Fairy was in the hands of a merchant). So, again, she was unavailable until recently.
Katrina was also unavailable until recently because she was only old enough to travel recently and it's only because she's old enough that she did travel: she specifically was fleeing her Village so that she didn't get ritually gangbanged now that she's of legal age to bear a child.
if MC had Fairy earlier he might very well have been knocking her up
if MC had Emelia earlier he might very well have been knocking her up
If MC had Kateryna earlier he might very well have been knocking her up.
BUT WE DON'T KNOW FOR SURE if he would have been knocking them up because all these cases are recent happenstance, SO PROVE NOTHING ABOUT HIS PAST FINANCES.
We only know that he can presently afford them not that he couldn't have afforded them say, 10 years ago when he had already had plenty of time to build up his business.
Regarding servants (which Emelia and Fairy are) he presently had the money to support them but just didn't bother going out and getting servants because ZAHRA ACTIVELY LIKES TO BE A HOMEBODY, unlike Rabiah.
Emelia was a gift from the queen and it's not wise to turn that down and Fairy was going to be killed if he didn't buy her or accept her as a gift so he gets them both EVEN THOUGH HE WOULDN'T NECESSARILY HAVE PICKED THEM UP OTHERWISE. All the same, he clearly ALREADY HAD THE MONEY TO SUPPORT SERVANTS.
(PS EDIT: and Fairy isn't even a servant who helps Zahra out with anything: she's just a mind-broke fvckdoll for MC to use, tho we can try to be nice to her and spend money on her as a result).
So none of this stuff proves his past finances one way or the other, if he could have had servants helping Zahra out or not, although she doesn't seem to really inherently want them. She'll accept them if they're given to her, but she seemed to have matters in hand
There's a big difference between conjecture based on evidence and conjecture based on what one wants to be true: the two are NOT logically equivalent.
We only know that he DID have enough to have 2 kids right off the bat, from the beginning of his marriage, strongly suggesting he WOULD have had decent funds in the interim unless he fell on hard times for a while.
It's a matter of probabilities, but the preponderance of the evidence says he at least had the cash and seems to have it at hand without any trouble now suggesting that he may have had a decent pile of cash for a while.
The fact that he can just blow money on renovating a room because it makes his daughter feel better suggests that he has more money than he's letting on, and may very well have been decently well off for a while. It's not a definite fact but it's a strongly suggestive pattern of presented evidence within the text of the story.
Yes there are plenty of potential real world issues, but none of them are actually convincing one way or the other without specific evidence.
OtOH, there are definite standout patterns of behavior including Zahra's bizarre behavior in trying to push Ain into becoming the new head wife when Zahra is nowhere near menopause, and her clearly preferring to keep taking loads into her from her husband, yet not having kids in 15 years.
There are a lot of factors which all coalesce on an interesting pattern, given actual evidence within the text, as opposed to making up evidence based on random possibilities.
