Captain William 'Dark' Markham was the leader of a band of Pirates who threatened the area around Markham's Isle and The City. He was the commander of the pirate vessel Catherine's Folly. After his death, he returned as a ghost to protect his ship and treasure against plunderers. Markham is an Apparition, with the sounds of a Haunt. Another difference is that he has his own special texture. He appears when Garrett steals the treasure in the hold of the Folly. Flash bombs kill him easily, with a minimum of two to four needed to kill it. The same rules of fighting a haunt with a sword apply here. The third option is to run for the water, where Markham cannot go.
