Deity-specific quests handed to worshipers, like Carl's kill order on Hellik or a god's demand for recruits.
Church quests are deity-specific assignments issued to adherents — Carl compares them directly to his own quest to kill Hellik. Of the four light gods who grant both Travel the Path and Welcome Home on conversion, two carry identical church quests: the new worshiper must recruit at least one more person into the religion.
Both of those gods, Theia and Khepri, provide a Prospect Congregation method letting volunteers take a day pass into the temple to see what they're missing. That recruitment requirement, meant as a growth mechanic, is precisely the hole Princess Vinata drives an entire court through every season.
The recruitment-quest system whose day-pass provision doubles as a warlord's smuggling route.
