They are a vampire type of Elf race introduced in Wraith of Lich King.
I think it would be cool if we got these race to unlock it would add to the lore and immersion cuz right now the closet we have is a Blood elf being a Blood Death Knight even then pretty much different.
Chances are no one has posted there in a few months thus the thread getting buried by newer ones. That being said I fully support this. The more race class options we have the better this game will be. (IMHO)
