She's a Witch!!!
I never played it but I came up with idea of a side-quest where the players run into a farmer with a pig who is upset that an evil witch turned his wife into the pig he has. If they investigate they find out the “witch” is just an innocent old woman, the pig is just a pig, and the man is simply off his rocker. Considering the murderhobo tendencies of the players I play with I seriously doubt they would figure it out and simply assassinate the “old widow theresa”.
