"Absalom, the Grand Bazaar if it still exists, otherwise whichever location you most expect to have multiple bookstores."

It is definitely one of the more inconvenient requests he could have made, but not outside the range of things he might predictably have wanted. 

Do it, she thinks. They have lots of books they've been faking for Keltham. She wants a team prepared to swap the covers and alter the first pages to match ones he might request from Absalom.

Fennelosa Teleports. 

Arayo casts Greater Scry, and there Fennelosa is, in the middle of a chaotic, bustling marketplace, the iridescent symbol glinting on his back.

Message:  Move the mirror close to the scry viewpoint and turn it around slowly.

It's his first glimpse of Golarion for real, and Keltham will be examining it carefully and not without a sense of wonder, for he may be in Ordinary Golarion after all.

Fennelosa irritably holds the hand mirror up to the scry sensor and rotates it, very slowly, so Absalom's landmarks can be seen in its edges. He has nothing to hide, yet. 

A skinny child tries to pickpocket him while he's staring up in the air doing something weird with a mirror. He kicks them.

...okay, if he asks he'll be told that this happens a million times per day, if the Conspiracy did it on purpose then they're - trying to distract him - it rhymes with other things, other worrisome signs, like he noticed under Owl's Wisdom months ago -

He'll do what the Conspiracy predicted, he supposes, in the version where they predicted that Keltham would think that being distracted and asking questions because a child got hurt was supplying the Conspiracy with the wrong retrospective incentives.

Message:  If possible, please carry out the rest of this operation while hurting as few children as possible, as little as possible.

"Acknowledged," Fennelosa says. The mirror is showing an absurdly tall lighthouse, the spires of some cathedral, a clock tower with incredible stone detailing, a flying person passing overhead, a pseudodragon perching to stare at them.

Another pickpocket brushes up against him and he levitates them fifteen feet in the air rather than kicking them.

Okay, nothing obviously out of line with the century-old 14-volume history of Absalom that was left in his bedroom in the 'Imperial Palace' where the Conspiracy brought him immediately after faking the 'Zon-Kuthon godwar', the point at which the Conspiracy started to take its game against him seriously.  That probably wasn't enough time for them to fake entire books, which is why they gave him a century-old set of 14 books, which is the sort of thing that Conspiracy Asmodia would not have permitted if she'd then been in charge, she would have had his room devoid of books rather than do that.  There's a lot of reasons they might be trying to hide something that happened in the last century, but whatever it is, it's even more likely to be in Absalom than elsewhere, and Keltham has any idea of what Absalom was like a century ago.

He can't exactly sight-read the city skyline - for all he knows, anything really tall could be the Starstone Cathedral - but the wide variety of weird tall buildings at least looks like 'Absalom' should look.

Does Keltham see anything that looks like a bookshop?

Not in the Grand Bazaar. It's mostly food carts, selling fresh fish and things just-arrived on merchant ships: grains, livestock, textiles.

Fennelosa asks, privately, if he should stay away from the slave markets. 

Ideally not, because they've claimed to Keltham that other places are worse than Cheliax and that'd be useful as evidence. However, if there are children in the slave markets he's going to have an entire full-scale breakdown about that. Someone should scout ahead, spend some gold, and get any children removed or illusioned into adults/halflings/gnomes, after which Fennelosa can walk through there as normal. 

"Okay if I hold the mirror less conspicuously, it's like advertising I'm not paying attention to my surroundings," says Fennelosa, weaving through a bunch of stalls of pigs and ducks and caged cats.

...call it 1.5x for Conspiracy, the description Keltham had read in the century-old book implied more of a chance that you could buy everything in the Grand Bazaar, where you would've thought that 'everything' would include books.

Message:  Head to where you'd expect to find bookshops, please.  Fiction preferred to nonfiction, if that distinction exists in Golarion.

(Fiction books are harder to coherently rewrite on the fly; easier to change a paragraph in an encyclopedia than to change a key plot point.)

"I haven't been here in a while, okay if I ask someone where to go?"

...Asmodia is confused by why they don't want Keltham having a full-scale meltdown about child slaves in Absalom, to the point of changing the fabric of local reality in a possibly inconsistent way about that; but she realizes this may not be the best time for Sevar to stop and explain her reasoning.

"Go for it."

Carissa would love Keltham to have a breakdown if it meant he'd stop pursuing Conspiracy. She suspects it instead means he demands Owl's Wisdom and Fox's Cunning.

"Good Wealday," says Fennelosa to a stall vendor. "I am looking for booksellers, where would I find those."

"You're on the wrong side of the market, sir, they're uptown from here."

"Thank you."

There sure are a lot of different people in Golarion.  Less variety in clothing, compared to dath ilan, of course; but the people inside the clothes sure are different - does that person have scales?  She's pretty.  Keltham will have to think about whether or not he's perverted enough to ask Meritxell to look like that next time.

A toad breathes fire at him from one of the stalls. A woman wrings a chicken's neck and hands it off to a tall, green-skinned orc. A beggar grabs at his feet and starts a spiel about his dying wife. 

And if he has a go-ahead from the lead team (which is covering up any Abadaran holy symbols they see as well as any child slaves) he'll cut through the slave markets, on his way uptown.

Go.

Absalom has periodically debated abolishing the slave markets. Not the institution of slavery, nor even the slave trade; both bring Absalom much prosperity. But the markets, yes. They're an unpleasant place, an eyesore both literally and metaphorically; they make people who don't mind slavery in the slightest uneasy. 

The slaves are mostly very minimally dressed, in some cases nude. Some are in cages, but most are for efficiency just chained to each other, shackled hands and feet. Most of them stare at the ground, or at the wall. Some are crying. Some are struggling. There's an auction block, where a man with a booming voice is collecting bids on a lot just arrived from distant Casmaron. 

There are no children. This required ripping some babies out of their mothers' arms before Fennelosa got there, but their owners were duly compensated.

And give the babies back, afterwards. Even nearly-fully-corrupted Keltham will care about that, not to mention that Snack Service is about to threaten me about it.

Snack Service would otherwise have advised Carissa Sevar against disrupting future relations with Keltham, had she been that silly!

The suspicious Asmodeans should really have enough evidence by now to update about some things!  They should not feel constrained in how they serve Asmodeus by Snack Service's presence, even if Cayden Cailean wouldn't like something.  Snack Service will warn them if they're about to do something that is about to significantly harm Asmodeus's interests simultaneously with Cayden Cailean's.
