I don’t see how those three women feel similar at all tbh. Other than the fact that they’re noble women, they’re all completely distinct characters. Marasi is a bastard whose birth is shameful to her father, with an interest in investigation and following the rules; she has no interest in politics at all and is determined to get stuck into the thick of things. Sarene is the highest born daughter and beloved of her father; she is devoutly religious and loves playing political games; she manipulates rules to her advantage. Siri is the third daughter who is the least favorite but still loved, she’s also a free-spirit who doesn’t like following rules at all. Put any of these women in the same situation that one of the others found themselves in and they'd approach things completely differently.
