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

[Valarya]

So happy you finally chimed in, Farseer. Hahah. While I don't want to get involved in the hermaphrodite discussion - the misrepresentation of Sa was annoying the crap outta me. So in case people aren't feeling very click-happy and don't want to do the research... I'm going to copy/paste something from aforementioned post #193 right here:

.....but Sa (at least as we are suggested of Sa thus far) has at least a female, male and a serpent aspect, as well as a jewel face. This use of the word 'jewel' in connection to the face could well be representative of the 'facets' of Sa (as jewels have facets and Sa, like Fool and many other characters, also has a number of facets) and/or be descriptive of Sa's actual, physical face eg scales like a dragon/Elderling.

As for the serpent aspect, Wintrow spoke of the followers of Odava when he went to Cress and Odava is the 'name' of the serpent god. Followers of Sa accept his part but followers of Odava believe Odava to be a god in his own right as they don't believe that he is an aspect of Sa. Possibly the male and female aspects of Sa could be El and Eda, though only known individually by those names in the Six Duchies and Out Islands etc?

Likely you'll find plenty more of all this over in the Mythical Creatures/Folk or earlier here in the Small, random questions threads, both of which will also include a discussion re Sa and connections with dragons and Elderlings etc.
