where it is stated that "The 'Black Elves,' or drow, are only legend." No statistics are given for the drow in this book, apart from the statistics for normal elves. The drow are described as purportedly dwelling deep beneath the surface world, in strange subterranean realms. They are said to be evil, "as dark as faeries are bright", and pictured in tales as poor fighters but strong magic-users. From 1978 to 1980, the Greyhawk adventure module series explored the drow in depth, including statblocks for drow and an introduction to their Underdark society. The first hardcover D&D rulebook featuring statistical information on the drow was the original Fiend Folio (1981). Gygax wrote this entry, listed under "Elf, Drow", according to the book's credits section. The text is a slightly abridged version of the text originally found in modules G3 and D3.

The third module in the series, G3 Hall of the Fire Giant King (1978) again mentions the party's need to find out whatever is behind the giants' alliance, and this time mentions the drow specifically by name. In the adventure, the player characters can discover the first hint of drow involvement in the fire giant king's council room, on a scroll which promises "powerful help from the Drow", signed by Eclavdra. Actual drow can be encountered starting on level #2 of the king's hall, beginning with a group of drow priests, and then other drow later. Having discovered that the drow instigated the alliance between the races of giants and its warfare against mankind,
