Many, many thanks to Seras for providing the sketches used to construct Luna's appearance in this page. Hope I didn't alter 'em too much for you! She has a gallery that you can visit through this link.
Non-Exalted players may be a wee bit confused. So behold! One of the faces of Luna, the God/dess of the Moon, Creation's chief trickster-type deity. In particular, the incarnation you see here is the Two-Faced Bride, who may appear as either gender but is always heavily pregnant in either. Now that's what I call mythology!
