I find it more reasonable that in Part 1, the white cathedral in Kessary fell due to committing cardinal sins like greed, as you mentioned. But if both cathedrals in the two regions—or all cathedrals—were like that, I wouldn’t believe it. It’s illogical. In Kessary’s cathedral, we see the men of the church give up and become fanatics of the one-eyed white monster, while the women simply become slaves because they’re forced to bear and reproduce for these creatures, so they resist and turn to stone. It’s clear there are no men, like priests or fathers, fighting back with relics or prominent male statues. But in Part 2, in the Arcezon region, the priest seems very determined. The trap paintings don’t look like monsters but more like magic, and since the weapons aren’t tentacles or mutated flesh, it’s likely he made a last stand with traps in the treasure vault of the church after leaving suppressive books in the library. The only place he didn’t protect was probably the dining hall, and in the library, the warnings like ‘don’t read’ suggest he knew some people might read them and use the elevator to do evil or cause harm unintentionally. The problem is, the monster succeeded. The spider paintings weren’t his creations, some monsters still got in, and there’s no trace of his body. Like how the church characters sent to check the eastern village were killed by parasitic villagers, their bodies consumed, the monster that eats corpses is the Master Lake, a version similar to the giant leech in the blood swamp but a fish-like monster like in Part 1. As for the giant flesh monster at the bottom of the lake in front of the church, there’s no point discussing it—it’s not an experiment but a creation of the final boss. The priest’s body might have been thrown into the lake and digested. That’s how it grew so massive—anyone who approached or was at the church was thrown in. Almost an entire village and a large cathedral were swallowed and digested, allowing it to evolve to that size. What do you think?
