Demon psychology: chaotic evil as exemplified thus and such. Sociology: Blai has not mostly encountered demons working together or talking about each other directly beyond "there are several dretches here instead of just one". Tactics: chaotic evil, as exemplified thus and such.

"This is very helpful. Demons are terrible interview subjects."

"I would expect so. One hears about the occasional one who stays turncoat long enough to give anything up and happens to find captors who feel secure in holding it, but few and far between."

"We can hold them"-- he says this with the same matter-of-fact tone Blai might use to say 'I can create water'-- "but they don't answer questions truthfully and interplanar shenanigans are always difficult to get past the provosts."

"I don't know about the provosts but you could try hiring Abadarans for the good truth spell."

"The provosts run the Archive, where we Yithians preserve all of the knowledge of the universe as best as we can. We have good truthspells-- does Golarion get the Nethysian truthspell?-- but even a good truthspell requires either a quite good idea of what you're looking for or a research participant who wishes to be helpful."

"I don't know of a Nethysian truthspell but it's possible I just haven't heard of it."

He flips through his notes. "Can you walk me through a typical day in the life of your Worldwound fort?"

"There are patrols going out several times an hour - every fifteen minutes in the ideal case - about half originating from my fort and the other half returning to the adjacent ones. Sometimes with horses, especially if the frequency is down for any reason like reduced manpower. Endure Elements is indispensable in winter and patrols often keep moving for the better part of the twenty four hours when applicable so as to not waste it; that's mostly wizards, some clerics, and we build up a supply of wands over the summer and spend them down over the winter. Wizards are otherwise on Prestidigitation duty - dishes, stables, people, rooms, laundry that's mostly blankets because people don't get out of their clothes even indoors when they can avoid it - and help man the parapets to keep watch and be ready to attack any approaching demons. Clerics also cover some Endures but are fewer in number, and also create water. There are classes on things like the treaty, the common Taldane dialect, and demonology, for new recruits or refreshers or just because it's boring there, and similarly various drills, sermons, card games played for imaginary currency or raisins... The standard food is stew that is usually predominantly composed of beef and rice because the supply comes in on an Ant Hauled ox that is then butchered on site but they do porridge with dried or previously frozen fruit in it during the time when day shift wants breakfast. The fort operates around the clock, with three main blocks of time someone may have as their sleep shift - the wizards are shifted a little because if one tosses and turns whoever wants the bed next had best not wake them up when they've only had seven hours. Patrols carry mail, so it's possible to get letters or orders or requisitions or pass around books, but it's slow and it's easy for something to be lost in transit or wind up going the wrong direction. Patrols have to be screened on entry, most typically with a Detect Fiendish Presence and, if the patrol contains a cleric, their squadmates vouching for their continuous observation."

"I don't know what you mean by the wizards being shifted? They have longer blocks?"

"More beds are allocated to a number of wizards than the same number of similarly ranked martials and they have slightly shorter required work hours though the First Arcane is supposed to investigate if they are actually using all of this leeway on a daily basis to see if they're using it to stay up drinking or illicitly gambling for alcohol rations or something."
