Due to an engineering miscalculation during the construction of the walls that enclose Sky Island, the lower district, known as The Murk, is regularly shrouded in a grey-green haze, the byproduct of the wall's fog cyclers, which is where the district gets its nickname.

The increased risk of living in The Murk has made it fertile ground for the shadier elements of the city. Here you can find anything... for a price.
