[@TheUnknowable][@Lionheart] [color=lightgray][i]I am wondering how the monsters were able to survive outside the fog and how he, and for that matter the captured villagers, survived in the fog, though.[/i][/color]

I could see the monsters performing raiding strikes, since the description says they attacked the village and carried people off. As far as the people surviving in the Fog, that all depends on what the monsters intended to do with them. After all, dinner only needs to be kept warm for a couple of hours at the most, presuming the monsters liked eating live food.
