The Reshi King from Rysn's interlude is probably trans. This statement is based on a few points
1: Everybody but Rysn (who's whole thing is that she's extremely green and unaware of the world) uses He/Him pronouns to refer to the reshi king.
2: When Rysn first meets the king, She genders him as a man, until she notices that he has breasts. This suggests that he has taken measures to present more masculine.
3: When Rysn refuses to call the king "king" his son loses his temper and tries to send her away. Up until then, he had been firm, but that was the point where he outright tells her to leave.
There is one line in the text where The king's son says "gender is irrelevant" in response to a question Rysn has about the king's gender.
I will say that this was written before the Author stopped using Gender and Sex interchangeably according to the WoB database.
Beyond that, I doubt the language they were speaking (thaylen) would have a robust understanding of sex and gender.
/u/mistborn was this your intention with the scene if you can confirm it? Or was it more the Egyptian style Hatshepsut-like others are mentioning?
I love Hatshepsut as an interesting quirk of history, and have long thought about ways to incorporate something similar. I did have that partially in mind when I was writing this, but more in the way that the culture was trying to understand him, rather than his own view of himself.
The king sees himself as male, and wishes to be treated that way--not just in title. In fact, in the coming months, you will see this character again briefly in some scenes I've already written, if you keep an eye out.
ooh are we going back to the Reshi Isles? Will we get a beach episode?
Ha. RAFO. :)
