If I had a group like this, I would have so much fun with the first one. Player paranoia is one of my favorite toys.

They show up and the ruler is healing children. The ruler hires them to help people constantly, even lets themself be taken hostage to free the previous hostage, a little old lady. But the whole time, they keep speaking in indirect ways, leaving things up to player imagination, which player paranoia would fill with devils and monsters. There’s nothing wrong with them, though. They really are just trying their best to help everyone. It’d be great because I know the players would be shitting themselves trying to figure out what nefarious plan is supported by setting up a hospital, despite there being zero reason to assume there is one.
