The Wolfwill is a ship belonging to Gundar Hardstriker, which was made for him after the Wolfcloud was destroyed in a shipwreck by the Araluen coast. It was named after Will, a good friend of Gundar, and made at the end of the Siege of Macindaw.

In the Emperor of Nihon-Ja it is revealed that the ship has been refitted with a new type of mast created by a half-Skandian half-Araluean boy called Hal, who appears in the Brotherband Chronicles, a new series by John Flanagan. This new type of masts make the ship go faster and also gives it the amazing ability of being able to sail against the wind.
