The World of a Conspiracy of Truths and a Choir of Lies

I haven't actually been able to bring myself to use the word galaxy in the actual text. It doesn't seem like a word that's appropriate for a fantasy setting, even though I think they were using it as far back as ancient Greece. Any kind of minor change to the atmosphere, and you don't see through it. But if we ever want to have mythology surrounding constellations or any kind of navigation relying on the stars, that we will have compasses.
