Rise of the Runelords
Sabyl has been running the House of Blue Stones for seven years, ever since her father died. She is a worshiper of Irori, the god of self-perfection and knowledge.
Evan a casual glance will note that she is in excellent physical condition, and anyone who spends time talking with her will find she is very intelligent.
She is more than willing to open her personal library to those who also follow Irori, though those who do not will need to persuade her of their good intentions before she will let them in.
