That was kinda the idea with GG. As an information broker any history she has would be under tight lock and key, and probably entirely fictitious. I wanted to keep the details here vague until I was able to fill in the blanks in character during play. As an example, I don't want to come out and say exactly how her family died since it might play into the plot at some point, especially if she's holding the details as a marker against someone. I'd be more than happy to confer with you privately to make sure you know what's what, but letting everyone in on the story right from the start may force your hand on where to take the narrative later on.
