Petra, one of the deuteragonists, is a warrior and a fighter known to be very tough and determined. Before, she often swapped known items for treasury before becoming a part of the New Order of the Stone(I call it the Modern Order of the Stone). If you thought she wasn't a part of Jesse's Gang, then you're wrong, since she is still a part of it. Luckily, unlike Reuben, she is still alive.
