Your character used to be a ghoul in service to another regnant, and was passed down to her current master (probably when the last one went into torpor or suffered the Final Death). The intimate relationship she shared with her previous regnant left her with information that could be valuable to others. During situations in which information pertaining to your character’s last employer is a factor, you should apply a +2 modifier on an Intelligence + Composure roll to see if she can recall anything useful.
