This game takes place in a fictional world, one related and which shares some historical characters and/or legends (ie Davey Jones Locker) but the use of gender is not anywhere a teachable lesson or a vehicle used to further any overt agenda.
In this world, the female captains are more open and overt than in our historical reality and females are in the nation-state navies but everything fits naturally in this world’s ethos and everyone’s role in the story seems natural and non 4th wall breaking.
The new Hero series should take note - by making the characters “normal” and part of the “natural order of things” this work advances the ideas that all types of people, no matter the gender identity, belong in the mainstream society and that it should be considered normal and not abnormal or unexpected.
