I'm putting together a plot in a Pathfinder RPG campaign where divs (aka daevas) are orchestrating the downfall of civilization. I'm trying to set it up so that evil is working indirectly, by corrupting people and then letting them destroy themselves on both a personal and international scale.
Can anyone recommend literature on plots akin to this? The texts linked to on the daeva Wikipedia page are mainly treatises on history and religion. What I'm looking for is good plots fitting my above description. Any source is of interest - RPG sourcebooks, system agnostic plots, fairy tales, comics would all be welcome suggestions. Also, please include why think that the source you recommend is a good one.
