The city above is being plagued at night by shadow people that wander the streets. Where they walk lights flicker out and a cold chill fills the air. They don't seem to be hostile but their presence is startling. At night it is best to stay indoors but they ignore walls and barriers so they will often walk straight through houses. In the event that one makes contact with a creature they experience an icecold chill that shakes the bones. As the shadows pass through the creature it's soul is pulled out and dragged along with it leaving the creature to witness their own body falling to the ground experiencing the horror and fear as they gasp for air that no longer exists for them only to get a 10 feet away, blink and wake up gasping back in their body. In the end they are tramatized but alive and well. The Mayor seeking to resolve this employs the the party to travel into the depths of a dungeon below the town that he has since kept secret. He has tried everything to keep them contained but nothing has worked. He has tried going down into the depths but can't endure the shadows or the feelings that over come him in the depths.
