Night Sisters

The Night Sisters are two elderly vampires who have fed on human blood for over 500 years and frequently ingested Elder Vampire blood in order to maintain their human appearance and avoid going insane. They are the Elder Vampire's left and right hand and serve him in whatever he needs. Their vampiric form does not differ much from their human appearance except for a couple of changes, such as larger, bat-like ears and enormous rubbery wings on their backs. Their physical abilities are far superior to those of any other vampire, including the supreme ones. They are very strong, agile, fast, and ferocious, and it is very difficult to survive an encounter with them. The only creature above them is their lord, the Elder Vampire, Valachian emperor.
