I'm planning a campaign for my home game set in Westcrown during the Chelish civil war, in part looking at what Abrogail / House Thrune were up to during that time, and wondering what published resources would be useful background reading as I put this together.
I've got the Inner Sea World Guide and Council of Thieves.
It looks like the campaign setting guide "Cheliax: The Infernal Empire" would be good, as well as AP #100 for the discussion of Aroden's church.
What else would be of interest?
Cheliax: The Infernal Empire has a lot of good background info. The focus is mostly on modern Cheliax, but there's some historical stuff as well. Council of Thieves has a pretty thorough write-up about Westcrown in the back of the first book of the path, if you haven't read that yet (I know you said you had it). The Hell's Rebels and Hell's Vengeance APs might also have some good info, though I haven't read either of them yet, so I couldn't say for sure.
Thanks -- the Westcrown writeup in the first CoT book is definitely useful, with a little reverse engineering of the timeline to step back the better part of a century. And some of the other books in that AP also have good bits and pieces that reference things that happened decades ago.
Wayfinder #11 is all-Cheliax, and has good stuff, but mostly "modern" / infernal-tinged.
