Reign of Kings Plague across the land at night

Ive been thinking about this for a few days I just have no idea how to go about it. Anyways, I'm fairly new to rok and my first day playing i ran into the plagued village not knowing what it was. Ever since I've seen that fog, I've thought it would be great to have the plague spread across the land at night and to steer clear of the fog you would just have to be surrounded by 4 walls and a door. Not every night though. Maybe an algorithm to choose a night at random. Idk, just a thought. and to steer clear of the fog you would just have to be surrounded by 4 walls and a door

 

nope. wait a few months. haha
