Mary Delacroix is an orphan who was raised for a time by Sister Justine ("Ju-Ju'), who tried to instill in Mary a reverence for life and God, and also taught her how to shoot. Mary went on to train to be a warrior nun. Rebellious from the beginning, she left the order to strike out on her own, in part because of a resentment over the preferential treatment the priests received over the nuns.
