Gwynne is an obvious crossdressing trap, whose androgynous beauty is only belied by his slightly masculine voice.  He behaves and dresses female in all ways, wearing lingerie, makeup, heels, etc.  He is beautiful. (unmodified starting CHA 18), and looks to be in his teens, if you dont see his elf ears.  His/her hair is black, complexion very fair, eyes blue.  He is very short, even for an elf, and built small as well.  He speaks common with a languidly aristocratic precision that bespeaks upper class background.  His/her demeanor is urbane and reserved.
