I suppose that might mean Nosferatu is out of the picture, but one of the preview clan images on the website (which are supposed to show havens, IIRC) was some form of alley or sewer. So, wait and see.Based on what has been said, that is my take as well. You were mass embraced with others so no one knew who your sire was or what clan you are so you’re put as caitiff. After a while you show affinity for one clan(have the right powers and/or outlook) and they accept you as one of their own.
EDIT: Thinking about it, its a clever way to introduce new comers to the clans and let them develop a play style that works for them.
