Many of these people can hedge out his thought detection sometimes, but none of them seem to do so reliably; he's reasonably likely to get people who were blocking him during the fight, or during earlier espionage.

Over time he can build up an impression of the churches and how they work. The church of Nethys doesn't have much in the way of centralized leadership, more like a collection of mentor-apprentice relationships and lots of owed favors, held together by shared bitterness about being driven out of their libraries and study halls by a bunch of resentful drunken second-sons and failed merchants who could have the respect they seem to want if they'd just become powerful magic users. They're objectively seventy percent of the firepower for their side but for the obvious reason not particularly coordinated in using it.

The church of Sarenrae is made up mostly of zealous recent converts concerningly eager to be martyrs for the cause of Good - understandably so, maybe, because their families and lives were mostly devastated by the first five years of the civil war and long wars have a frightening tendency to drop you out of Good. They worry that the rebels will not bother to have orphanages, which usually the good and lawful churches run. They are in the constant company of summoned creatures from Nirvana, many of which have true seeing and will hiss at Aroden if they see him nearby. 

The church of Norgorber is not very invested in winning the war because their main aim here, war profiteering, is going great. They're also getting magic weapons shipments from some idiot who thinks he's "helping" and is - well, probably helping but also making all of them very very rich. 

The church of Calistria is here to avenge the destruction of their temple in the early years of the war. It's not actually clear the rebels were involved in that but since then they've accumulated a bunch more things to avenge. They've encountered a lot of evidence pointing to the rebels being responsible for various atrocities in other cities, too. (The evidence...is if anything a bit too convenient, but if you're starting out already very mad at people maybe it's persuasive.)

Malduoni carries all of this information back to Onaku and the wizard in charge. Along with a few of his ideas. 

He thinks any plan to placate the church of Nethys into leaving will be helped by giving them back at least some of their books. He knows some left with the captain and ship but maybe they can set aside the rest in case an opportunity like that arises. (He will, of course, read all of them in the meantime and take copious notes.) Also, if they ever get to a point that this is even feasible or relevant, they should consider blatantly running orphanages and other public works projects, to show the Good churches like Sarenrae's that this isn't a case of innocents being oppressed. 

He wants to know what's going on with the weapons dealer "helping" Norgorber. The rebels unfortunately don't have the resources to spy further afield, but he wonders if he can set a different church to chasing this down. Probably Sarenrae, they'll have the strongest drive to - objecting to Evil things being done on principle, even if it's in service of a cause they share. He can try to point someone's thoughts in that direction, with Suggestion or with Lesser Geas if necessary. 

He really wants to know who planted the evidence for rebel atrocities in various cities. (He assumes it wasn't in fact the rebels but does check this.) Currently he would be betting on Asmodeus. His best idea so far is to wander around eavesdropping and try to find someone who's close to noticing that it's too convenient, and Suggestion them down the next few steps, of finding this suspicious and wanting to investigate further.

If he were Asmodeus, he would have spies amongst the churches forces. He hasn't seen any direct evidence for this yet, but will keep listening. 

They are enthusiastic about the idea of running public works projects but there aren't actually a lot of young orphans in the city on account of there having been a siege going on for months now. Maybe they could do other public works projects than that? Some people are coming up with designs for a water system that does not rely on clerics making clean water from nothing.

He hadn't been thinking of orphanages now, this would be - in future, in the scenario where they're winning and taking more territory. Designing a water system is an excellent idea.
