Shadowmoor was once the world of Lorwyn — in fact, in a sense, it still is. But thanks to the Great Aurora, everything's changed. Where it was once constantly sunny, now it is always night, steeped in gloom and fog, with only cold moonlight to light the skies. Once-clear waters have turned brackish and chill. The howling wind creaks the brittle branches of rotting trees. Life, once abundant, either struggles to survive or is twisted into something vicious and cruel. This is not a world of despair, but of oppressive terror and constant death.
