More of the Drow

“Drow are a dark-skinned sub-race of elves that predominantly live in the Underdark. They are generally evil... are shorter than many other sub-races of elves and, in common with most Underdark-dwelling creatures, have a tremendous resistance to magic. They also have a much higher birthrate than most other elves, but strife tends to keep their numbers down.”
