The Mistmarcher was a sky pirate sky ship that was present at the Battle of the Great Sky Whale. Before the battle, Filbus Queep discovered that a long-lost cousin had become the Mistmarcher's head cook. On the way to the battle, it ended up going through the turbulent fog that got in the way of the fleet, but it survived without too much damage. Midway through the battle it abandoned the fight. Years later, in 51 ᴇ.ʏ., the Mistmarcher was grounded in the Armada of the Dead, and it was finally destroyed when the dark maelstrom struck.
