I'm more worried about them being on guard for the next regular old, run of the mill, monster encounter.

As much as the Nightfall is a big spooky end-of-the-world. I'm worried about the next few weeks, few months. And it isn't clean, it isn't nice. I'm also in charge of the floor so if you've got an issue with it, you can either suck it up or try to pick a fight with me.

I wouldn't try it.
