Wastes of Ancient Shadow
No one says “Welcome” on the Wastes because your not.
The Wastes of Ancient Shadow are just that, a vast and dangerous wasteland full of corrupted magic and unearthly horrors. Its not empty by any means. Decrepit abominations roam the plains and deserts feasting on anything they can catch.
There is no map of Wastes. The land is dimensionally and temporally unstable causing the random addition and reorganization of the land scape. A party travelling across the vast plains of Wastes toward the Shattered Spine Mountains may start to believe that they aren’t getting any closer because they aren’t.
Monsters of the Wastes can emerge from anywhere and from any point in the past. Wastes have no future.
