So I like to listen to soothing music while I write and I was looking for something new when I stumbled on this. I saw the video playing and thought, "That is exactly how imagine flying on Lilly at night is!" Remember the scene near the end of Book 2 where she takes them up above the clouds for the first time at night. The world melts away and becomes rolling clouds below and stars in a black sky above. This is the image I was trying to capture.
