A ship, made of grey wood, named the Moon's First Daughter. The Fog Ship was able to repeatedly run the Savanna blockade of the Butterfly Kingdom, making the journey in about twelve hours rather than the standard 2-3 days. Kiri, a friend of Cai-Wen, used to be an officer on the ship. Captain Xie is a tall, thin man, pale as his ship with odd light grey eyes.
The ship visits Three Piers, where it brings the inhabitants news and supplies.
We are not supposed to tell anyone about Three Piers or its relationship to the Fog Ship, or any of it, really.
Lijuan got a tour of the ship, but in general people were required to stay in their cabins while the ship was under way.
