Most evidence points to the mysterious dark elves as being an early developmental form of the night elves. It is hinted that the dark elves, possibly along with others (the book says, "others came, lesser forms, minute life spans"),DotD 161 had something to do with releasing the Burning Legion on Azeroth.
According to interviews and references made in The Art of Warcraft and on the The Making of World of Warcraft DVD, night elves were based off the dark elves of other fantasy settings (especially the drow from D&D), but their personality and culture were made to be the direct opposite of the culture and personality of dark elves.
A story nearly identical to the one told about the dark elves in Day of the Dragon is later related to Khadgar in The Last Guardian by Medivh, where he gives these ancient magic-users a more familiar name: Kaldorei. It seems most likely, therefore, that the "dark elves" are in fact the night elves under an earlier name.
