The Shadowfell is what the world will be like when entropy has claimed it. Likened unto the world at the end of all things, it is devoid of life and emotion. No birds sing or insects buzz, nothing natural lives in the Shadowfell. Where natural rivers and forests are in the mortal realm, only dried river beds and dead marshes exist. Cities, villages, and towns are massive sprawling metropolises. Unlit, and inhabited by the dead, these cities offer no comfort or refuge for travelers. The Shadowfell is home, however, to the Unseelie Fey court. And it is from here that they wage their wars upon the Feywild. Travel to the Shadowfell is often by accident – walking through a graveyard at midnight, turning down a dark alley, or other unfortunate event often leaves the victim screaming and running through a nightmarish hell before they are killed and consumed by some long dead thing.
