The Fool (spoilers for all RotE books, including LST)

[finella]

Artanis is absolutely right in stating that Sa is most commonly referred to as male but there are several places within the text, especially during Liveships, where you learn the deity is a duality of male/female.

I just finished LST. In "Ship of Destiny" there is this scene, when Althea escaped her cabin after Kennit had raped her. In the companionway she met Wintrow and Etta and shouted out her accusations. There it says "But for their (Wintrow and Althea) expressions, they looked very alike. It reminded Kennit of the old depictions of Sa, male and female, face-to-face on the ancient coins."

So in former times it was common, that Sa was both, male and female. (Sorry, that I come back to this. But reading this passage, I had to think of this discussion here )
