I'm trying to create an adventurer from a fortress I founded and retired, but there are seemingly no options to select any beliefs. I tried reclaiming the fort and setting up temples to specific deities that some of the citizens believe in, and then retired the fort again and tried to create the adventurer, but still no beliefs. Is there a minimum number of followers of a deity/sect required before the option to believe is available for an adventurer? Is there a configuration option to make this 1? Or is it something else?
Edit: I was looking in adventure mode articles and articles about beliefs, and didn't find the answer, but I think I found the answer in
https://dwarffortresswiki.org/index.php/DF2014:Temple. It looks like just having a temple zone isn't enough, it has to actually be an official temple requested by petitioners, of which there must be 10 by default. Haven't tried it out yet, since that's some work, but this is probably the answer.
Edit2: Well, I changed these settings:
[PRIESTHOOD_UNIT_COUNTS:1:2]
[TEMPLE_VALUE_LEVELS:2000:2001]
Since I already had a temple worth 2000+, just to check I lowered the temple complex value too. I have more than 2 worshipers of various religions in the test fort. I lowered the guildhall levels too to see if it did anything after initializing the fortress the first time. It does. I have 2 guilds of 2 workers each that popped up. There are no petitions for temples. I tried in adventure mode again to make an adventurer with the established temple complex that has no priest, and it still isn't working (no beliefs). I am keeping the fort going, but still no petitions for the temple or a priesthood. Not sure if I'm still doing something wrong or missing anything.
