Drows are the D&D "Evil elves".
They have black or very very dark skin tones, and live often in the underdark (Underground drow societies), except for followers of the surface (And good) Drow Goddess of Dance and hunting Eilistraee.
They are Matriarch (Women rule...and men are for breeding, some high level roles, or plain warriors and slaves), and worship Spider gods and goddesses, the biggest being Lloth. Some drows who fail her are turned into horrible things, something along the lines of a spider legs and abdomen, yet a drow body and head.
Dark elves seem a little Matriarch (Pirotess has some sort of Dark Elf guard who punches a human who probably wants to fook her.

), and are tan or dark skinned, but not nessisarily Black.
Night Elves are the WC III creation, a sort of Wood Elf and a Drow/Dark elf.
Purple Skin, a sort of Matriarch society, except that its just lots of females and fewer Males, and more in tuned to Nature than Magic.
Deedlit is a High elf, or a Sun Elf (Tan/white skin, blonde hair), since while her magic is more shamanistic or something to that matter, shes a creation of the anime.
HAH! I am such a geek.
