The Monolith of Kal'Doram

From the introduction: There are few things more concerning than that which we cannot affect. Environmental phenomena happen whether we want them to or not. One phenomena in particular that has been utilised more than most in the building of suspense, uncertainty and horror is fog. It envelops everything it comes into contact with and obscures the vision of everyone either inside it or attempting to see through it. This encounter exemplifies the idea that we cannot affect nature and that to attempt it will only work against you.
