The Gargoyle's Slipper
The Slipper was the ship under the command of Captain Morganna Fox, a well-known and dangerous pirate. It was a lightning-runner, with a hull as black as the souls of its crew, and reinforced rails with over-sized harpoon tips she used for ramming and hanging onto wooden flying vessels.
The Slipper was recently wrecked in the mountains of Mars, having been damaged in a lightning storm and pursued by the H.M.S. Gallant, which mistakenly ran into her, destroying both vessels. Most of both crews were lost, and the remnants were taken by the guard of Archduke Percival Edmonton, Prince of Mars and Lord of Warton and surrounding territories.
