"I am appropriately terrified and really do not want to do this again with nothing more than a glance at a standard circle." 

Which is not to say there are no circumstances under which he'd try. If an army of apsels could defeat not just Cheliax, but Hell itself, and this one decides he'd rather go home – well, he might destroy the planet, but some things are worth it. 

"Cool. I am actually qualified to teach the semester course, but like, lesson one is finish the semester course, yeah?" And he pulls up an image of a standard Safe Summoning Authority circle on his computer. It's paragraphs of legalese written in a tight spiral around a circle.

"You know, my school had a mandatory course on safe devil-binding, I wonder if it's similar. ....Devil-binding isn't safe, if you're wondering." He's not going to memorize the legalese but he also wouldn't have guessed that writing the binding out in plain whatever-that-language-is would do anything.  

The picture winks out. "Good to know! Daeva can't summon daeva, I have no idea about summoning devils, it doesn't sound like it would be very fun."

"It's really not! They intrinsically value producing unfair contracts that screw the other party over." 

"How oddly specific of them. Why are they like that?"

"Asmodeus is the god of unfair contracts, among other things, and devils are the things you get when you torture people until they stop having free will and become automata in his service." 

".........is this process also magical in some way, I don't think torture victims back home ever spontaneously start talking about how much they love unfair contracts."

“I think it takes hundreds and hundreds of years. Though it wouldn’t surprise me at all if it’s magical and they just do the torture because Asmodeus likes it.”

"Ah-huh." Well. Dude has food, Cam has reading material. What's it say?

Depends on what he wants to start with. Last week's edition of Egorian's largest newspaper? Imperial Betrayal? A History of the Empire of Cheliax, With Particular Reference To The Civil War Lately Occurring In That Nation? A child's theology primer? The memoirs of some dude named Pierre Mariano Ramon de Montserrat? 

Let's start with the child's theology primer, since he is new to this.

This one's from an Abadaran publishing house in Absalom, written "for the edification of young people intended for a mercantile career, so that they may become familiar with the beliefs and customs of other lands in which they may be required to have dealings."

Everyone agrees that the world was created by Pharasma, the goddess of birth and death, the anchor of reality, the sole survivor of her own long-dead universe. At the birth of creation, Pharasma willed into existence the inner and the outer spheres – the inner sphere comprising the Prime Material, Elemental, Astral, Ethereal, Shadow, and Positive and Negative Energy Planes, the outer comprising the planes associated with each possible combination of alignments on the axes of Good-Evil and Law-Chaos. She also created the eight oldest deities, though there's a fair amount of disagreement about which ones those are (though the authors feel strongly that Abadar is included). These days, of course, Pharasma occupies herself sorting the souls of the dead into the appropriate outer plane (Axis is best, but it's rude to say this some places and outright illegal in others, here's a list).   

Most of the rest of this book is about regional differences in the worship of major dieties of the inner sea region, if Cam's interested in that sort of thing. 

He is at least interested enough to skim that part quickly so he will recognize names as it comes up and know which ones are. Y'know. Evil.

Asmodeus! Zon-Kuthon! Norgober! Urgathoa! Lamashtu! Rovagug! 

Okay! Them's the evil ones!

Newspaper now.

The imperial army reports another great victory over the filthy rebels in Andoran! Here's a report of the battle. Here's a list of towns whose adult inhabitants have been put to the sword (the children, of course, will be taken in by loyal Chelish families). Here are the penalties for trying to avoid conscription. 

There was a fire in Corentyn's dock ward Oathsday last. Four warehouses were lost, but a navy wizard on leave was able to stop it before it took down half the city. 

This guy is advertising his magic items business. This other guy has good farmland convenient to the city for sale or rent. This other guy wants to sell some halfling slaves; here are descriptions, they're all healthy, fertile, and good workers. 

His Infernal Majesty, Infrexus Thrune, King of Cheliax, Archduke of Taldor, by leave of the great god Asmodeus protector of half a dozen other places, repaired to his country estate at Cornellà for the beginning of the fox-hunting season. 

There were three public executions for heresy and insurrection this week. Here's all the gory details, complete with illustrative woodcuts. Traitors should be grateful for such a death, which is still ten thousand times more merciful than the punishment awaiting them in Hell. 

Surely if... punishment awaits them in Hell... they should not be grateful for such a death... this would make more sense if they were being kept alive under awful conditions, probably?... whatever, this does look pretty icky. History of the Empire etcetera?

This is one of the ones with both censored and uncensored versions!

The uncensored version starts when Aspex the Even-Tongued, then the governor of the Taldane province of Cheliax, declared its independence and proceeded to take over most of the rest of Avistan. Cheliax became the greatest power in the inner sea, and the seat of the worship of Aroden, the god of humanity. About fifty years before this book was written, Aroden was supposed to return to Golarion and usher in a new age of glory. Instead, he died. This caused worldwide famine, opened up a permanent planar rift to the Abyss in the former nation of Sarkoria, created a permanent hurricane that still occupies a good chunk of western Garund, and plunged Cheliax into decades of bloody civil war. By the time Abrogail I of house Thrune made a compact with Asmodeus and seized power, thirty percent of the population was dead and the survivors were too exhausted to care. 

The censored version starts with the death of Aroden. The names of House Thrune's most prominent adversaries are elided. There is some interpolated moralizing about how Aroden's defeat by Asmodeus is proof that mortals who try to rise above their station will inevitably destroy themselves and everyone who ever trusted them. It is otherwise reasonably complete. 

What's the content of the compact, can he get that?

Nope.

"What's a halfling?" he asks his native guide.

He's alternating watching Atriama and casting Detect Magic at the apsel until his head can't take it. 

"Humanoid species, about so big, stereotypically cheerful and happy-go-lucky. I think they're nomadic normally? Most slaves in Cheliax are halflings." 

"How many sapient species are we talking about here?"

"Here in Galt or on Golarion or just in full generality?"
