Out of the Abyss
Denizens of the Underdark
"Drow, also known as dark elves, are a dark-skinned sub-race of elves that predominantly live in the Underdark. They have earned their reputation as evil people, with all justification, though some members with more neutral disposition do exist, as do an even smaller number of actually good members. On the surface, the drow are sometimes referred to as "The Ones Who Went Below".
