For years now, the sailors and pirates of the Lost Lands have been talking about a ghostly ship sailing in the heart of a storm. This vision disappears as soon as it comes to life, yet witnesses still spread rumors... About a huge octopus traveling with the ship. About its owner, the captain. About the Yarl's rage and his curse. And the sorceress they believe is responsible.
Meanwhile, somewhere else in space and time, Susan finds a strange pirate chest with the compass of the worlds inside, and a note begging for help. It's time for her to return to the Lost Lands again.
