I'd like to see the danger of "Old Night" make a comeback. Not at the level of, "You can't go outside or you die, even if you are at level 20" like some events have gone to. But ... just a very high chance of something spooky happening any time you go outside at night. Maybe some monster or group of monsters that attack at any old place at night, not just the Vallaki outskirts. Instead of wiping out all resistance, the monsters could keep pressing an attack and spread the savagery around until *some* PC falls, and then take off with the body for a time. Or a spirit that places curses on people, if they don't RP their way out and then fail a rolled check or two. Wererats could invade the crafting shops at night, do some damage, and leave. Angry elf spirits could come out of the woods and do ... what ever angry elf spirits might do ...
