As the one who's done a lot of the planning IC, as I understand it the plan has gone: Attack the city, burn the mill, devour everyone possible. Then revised to: Avoid the keep,raid the food supply while they're holed up. That was pointed out as nonviable and things were shifted too the "Lightning raid" as of the scouting mission. To just get in and out as fast as possible. Minimizing human damage for maximum conversion potential.<br/><br/>Post scouting mission we're probably looking at something like: An attack goes through the drainpipe if they/we can manage to get through that door, otherwise that detachment is diversionary. The mill is being burned as the time needed to eat everything in storage is too long. People who flee to the church are getting devoured by the PCs. Unnecessary deaths of non-combatants and surrendered defenders are discouraged among the rank and file.<br/><br/>It's less "Siege them in and starve them." than it is "Destroy the food supplies so people start going hungry." We don't have the time or manpower for the former.<br/><br/><br/><br/>A period of time later some volunteers and possibly Lilissa return to the town. The volunteers peacefully preach Taimat's teachings to encourage the embracement of vore among the population. Thanks to the heretics remaining nearby and still actively attacking Lilissa has the cover of pursuing them with the help of some adventurers she met outside the town. Likewise our attack can be pinned on the heretics. Giving the evangelizing cultists a "No no, those were heretics. We are the truthful followers here to help you through this." way out of accusations of being the raiders.<br/><br/>The loss of Tyr's cleric will likely increase the effectiveness of those efforts greatly.
