The Mourneland

At one point during the Last Battle, something triggered a deadly, twisted mist to complete cover the planet. The mist either killed or mutated everything in its path. After The Cataclysm the outer shell of the planet became known as the Mourneland. Rumors of deadly, mutated monsters crawling across the outer surface of the planet are whispered throughout Atrea. Every so often, rumors of something crossing over from the Mournelands into Inner Atrea will spring up in an outer village, but no one has been able to see or confirm with their own eyes the existing of such creatures, nor is anyone sure what happens to them after they are supposedly captured and whisked away.
