The Women of David

The Women of David are a intern sect inside the Vampireark Ages Clan of Cappadocius. As far as I remember, they are most common around Constantinople.
The roots lie in the fact that Cappadocians lack the ability to perform the "flush of life" (to appear alive). Thus, they have to find a way to conceil their dead-like pallor.
One day, they stumbled across a conservative tribe that cleped itself "The people of David". They had a strict dress-code after which the women had to go either veiled, or wear a make-up, which made them look pale, and take belladonna, so their pupils widened, appearing completely black. Furthermore they painted thir lips in a deep crimson.
Because this style looked so very similar to the Cappadocian's appearance, some of them infiltrated the tribe to live as one of them and make the people of David their disguise. Thus they wandered the nights of Constantinople without being recognised for what they are.
As the time marched on they recognised how very good this worked out and that they weren't even recognised by other Cainites. This made them perfect infiltrators and assassins.
