Barovia has a dark feel about it. From the gothic style homes, to the overcast sky, to the roving monster hunters.
It grows cold enough in Barovia to coat the land in a foot of snow even throughout most of spring and fall. When it isn’t snowing, its raining, or at least it seems that way.
Vampires and Were-creatures are a nuisance in these lands as the overcast shields them from view.
