Foreign Fog

Pleasure to meet you, adventurer. I wonder if you might be willing to help me with some research? I'm sure you've noticed the fog beasts that have recently started encroaching upon this area. People see them as a bad omen, they always seem to show up during periods of ecological imbalance. I disagree with this assertion. Still as an expert in all vapor-based magics, I've been hired to find out where they're coming from so they can be cut off at the source.
