A deep gloom is pervasive in the skies above, the ground below, and in the dark waters all around. A silent song can be heard echoing around the withered trees, and faint wisps and lights can occasionally be seen dancing around in the dense fog. If you brave the many mundane and magical dangers of the swamp, you may find and ancient and majestic castle. Ivy and moss cover its walls, and ghost villages can be found scattered around it. Welcome to the Howling Marsh, the domain of Karthus, the Deathsinger. Visitors are welcome, assuming they can walk on the razor thin edge of Karthus' good graces.
