I have a campaign I'm running that heavily involves cultists working to save the planes in a kind of "we live here too and would prefer not to die" motivation. There is a cultist that one of the players has a history with.
The party consists of a warlock, ranger (the one with the history w/ the cultist), fighter, wizard, and paladin (who I expect will have the most trouble with accepting help from a cultist).
The group is currently working for a church that, unknowingly to them, actually trying to purge the world which is what the cultists are actively working against.
I want to introduce this cultist NPC to help them out a little, and guide them to the knowledge that their church is actually working against them, but want to be able to do so without the group immediately going to kill them. Is there a way to do this, or have I dug myself into a hole?
