Tales of the Fourth Age
The Drow are a reclusive race that inhabits the Underdark. They are hardly ever known to initiate contact with any of the surface-dwelling races, and almost all of the contact with them occurs when people seek entrance to The Under-Gate.
What is known about the Drow are that they seem to be related to Elves in some way. Some scholars have speculated that they are even a sub-species of Elf, in much the way of Wood Elves and Sea Elves, going so far as to call them Dark Elves. If this is true, it has not been confirmed by the Drow or the other Elves.
