Silvia?

This is less of a question on what she can do, and more of one on who she is. I mean, I wonder due to some hints of her backstory (From what Zer0 said, met a Salubri as well as what she's willing to say in TFN).

But my question is basically: Who is Silvia Black and what is her Backstory? Only if it's willing to be answered, if not then please feel free to delete this topic. D:

She's an ex-Fu Syndicate member would use to hunt vampires but almost lost her life doing it. She was rescued by a powerful Salubri and he began teaching her peace and the path to Golconda. She quit the Fu Syndicate and began helping him instead.

That's all I can tell you for now however I do have ideas on expanding her character.
