I'm really enjoying this little fantasy yarn. I have a moment that I'm building towards, but everything that's coming up in between is coming to me as I go along. We'll see what obstacles await our intrepid seekers in the days to come. If we're really lucky, we might even find out their names! Anything is possible in the wonderful world of writing!
