Ma'at's pretty tough to miss. You can find her near the scales of judgment and she always has that feather poking out of her hair. It's pretty, yes, but be careful. It's also the feather your soul will get weighed against after you die. So watch out! Oh, and one other thing: when you do see her, please make sure you don't lie to her. She really, really hates that.
