The swamp was normally a quiet place, filled with only the ambient noises of birds, bugs, the occasional amphibian, and the even rarer rustle of the wind through the rushes which populated the boggy landscape. Not a particularly peaceful quiet, per se, but things had a way of feeling still in the humid air, as if the oxygen itself was stagnating. Of course, that was just a side-effect of the carbon dioxide being put off into the atmosphere from all of the things decaying in the general vicinity of the swamp...but it was really better not to think about that.
However, it was singularly difficult to think about much else aside from the stench which seemed to seep from the very ground itself, an eye-watering aroma that hinted at death and other unpleasant things. In the middle of the unusually warm summer day, the damp (and in some places, boggy) ground seemed to simmer and bake at the same time, letting off putrid clouds of whatever noxious gas was hidden just under the wet dirt. The trees scattered throughout the landscape hardly did much to mitigate the heat - instead, they somehow managed to make it look even more bleak and dead, as if the greenery was just barely clinging on to life in a world of muddy brown hues. All-in-all, a lovely spot.
