you give them too much credit. Neither Merlwyb nor Kanne-E-Senna have done anything to actually help you up to this point. It was Merlwyb's second in command who came up with, and executed, the Leviathan plan. All she did was complain about how she didn't know what to do. there isn't a single useful female character in any position of power. They're all figureheads.
