What's the darjest Opeth album in your opinion?

The atmosphere in Ghost Reveries is somewhat dark...but tbh havent considered any of the albums as "dark".
 
The only acceptable answers are Deliverance and Ghost Reveries, the others don't come close, /thread :)
 
In terms of the mood of the music..... My Arms your hearse, no contest. Then Watershed or deliverance.
