Mist rot

I just had an interaction with the rare and ever ominous Mist rot, it is a disease obtained by the Mist in the dead end, I was told that the level I had witnessed was stage four, he had boils all over his body and anyone whom touched him had to get decontaminated including his wife Margry whom was taking care of us and providing food and drink for us before we start our adventure, I truly hope he gets better.
