Powerful women as in they all are very skilled in magic as well as high up in a political hierarchy.
So far no femdom at all (other comment says there's one scene that kind of is, woops). Though I wouldn't doubt the possibility of there being some femdom in the game in the future, preferably optional. As it AND its maledom counterpart are surprisingly common fetishes in these games as I've discovered.
I do believe that there IS setup for maledom in the future though with a specific character named "Anwen" who has some fantasies about it. Oh and the game also includes a harem route. Also took a look at your comments and saw that you dislike lesbian content, so I should mention the game has setups for some of that too. When it reaches that point, I believe you can discourage and most likely prevent a "lesbian-yet-still-in-the-harem" style relationship between two of the characters. Where they are both with each other AND you/the MC.
