The Crying Priestess

Once an Aztechnology assassin, now a bogey man haunting the Noose. There were rumors that she was a banshee, but it turns out that she's a Nosferatu, and that she turned over a new leaf when she caught HMHVV. As a Nosferatu, her corporate bioware is now... different, and she doesn't have to kill every day. While sometimes her hunger forces her to take a life, now she prefers to offer a service of providing euthanasia to those who want a peaceful death. 
The Priestess has long ties to Mercy and Silver of the Pure, back from when she was working for Aztechnology.

You choose murder. I live by it.
