Ghost Pirate Captain

Undead prowling the ocean on derelict ships have long been threats sailors keep an eye out for. Other than corporeal undead, some undead pirates take on an incorporeal form, especially if their bodies have been lost to the fishes. Captains of crews in particular are likely to return from the dead, perhaps on account of their strong personalities.

Tethered to the world after death by powerful emotions that haven't been resolved, ghosts haunt the living as sad echoes of their former selves.
