The Underdark.
A place of brooding darkness where no shadows exist, and where Drizzt does not wish to go. The noble dark elf must return there though, must go back and find his friends in the great gnome city, and then travel on to the city of the drow.
Only then can Drizzt deiscern what perils might reach out from the dark place, to threaten his friends at Mithril Hall.
