Oh, right.  She was a Lunar.  She could change her whole body, so changing something like skin and hair color was nothing.  "Hmmm..."  Mera thought about that when she was asked the language question.  "High-class, educated, traveling with a Terrestrial bodyguard..."  Mera tapped her foot.  "Are those all you speak?  Most Sijanese, even if they aren't part of the funeral business, speak Old Realm.  Language of spirits and all that.  But if you don't, then go with High Realm.  I don't speak it myself, but I can get the gist of it enough.  Basic idea: don't speak the local language, and I'm your translator in addition to bodyguard, okay?"
