Ok the story is about the prince (Aurelius) being a homophobe and transphobe, etc. He threatens the hermaphrodite slave and tries killing it but his father (the king obviously) wont let him hurt the slave (love story? Seeing what's in the heart, not the body) and the prince, angry and hateful because there's (what he calls) a freak in the castle and it is allowed to live, runs to the forest and is tricked by evil, flesh eating pixies (smaller and meaner than Faeries) and the faerie prince/princess saves him and starts to hang around the prince and they become friends, etc, etc, by the end of the story, the king dies, the prince talks the hermaphrodite slave into killing itself for the sake of the king and he finds out the slave was actually his half brother but became a slave (metaphor for a second class citizen, sort of like blacks were in America even after they were considered freemen, they were still hated and abused) because he was different.
Well somewhere in the story, the prince marries the faerie princess, but because he's only like 12 in the story, he doesn't see him or her naked (so he doesn't know anything about it being either a boy or girl) and he finds out the faerie was actually a boy who just liked wearing girlish things and had a high voice and was just playful and cute lol (btw I actually was basing the faerie on Ed but I wanted it to go the other way around. People thought ed was a boy but her father reveals Ed is a girl)
