From what I can gather from various wiki's, the book The Order speaks on some of this and says that her mental state was declining from her contact with demons.
What I am wondering is
1) Any details about her psyche? Perhaps signs of hitting 0 San and becoming a cultist?
2) AFAIK the book doesnt say she is dead. So.....is she still alive?
She was last seen in Caldeum. Any easter eggs hinting at this, or where she may have went?
