Fonferrus

 is a galleon ghost ship in, helmed by Lucia Rivan, a Darcozzi Paladini turned Death Guard.

Background
Known as The Floating Hangman, the ship is a frightful legend among sailors in the Deadfire. Many sailors fear the Hangman, and flee at the first sight of thick fog, an omen of its arrival. It is rumored to have a crew of undead, captained by a visage of death itself, and the ability to magically clear even the roughest storms.

The hangman is the resurrected remains of the Grand Vailian galleon, the Fonferrus, meaning "Iron Strength", a ship that Darcozzi paladin Lucia Rivan used to flee the burning palace when charged to protect the royal family's sword, the Engoliero do Espirs.

After being tracked down by Yseyr the Berathian, Rivan was slain during the ensuing fight at the Battle of the Dusken Isle. Himself being mortally wounded in the battle, Yseyr retreated to Neketaka and begged Berath for another chance to serve his cause of protecting the sword, even in death, thus becoming a Death Guard. Out of sheer will and faith, Rivan too rose from the dead, spawning a crew of undead to aid her. She now roams the sea in the tattered ship, attacking unknowing vessels in hopes of one day coming across Yseyr and reclaiming the sword.
