The Nocturne -also known as the Vampirate ship until Tide of Terror- is a ship crewed by vampires and shrouded in mystery.
It is the ship that rescues Grace Tempest in "Demons of the Ocean" after she nearly drowns when her boat capsizes. It is a strange ship cloaked in mist with red deck boards, stately cabins with elegant decor, a banquet hall for Feasts, and a beautiful figurehead dressed in 20’s attire. It is later revealed that the figure head is a female vampirate named Darcy Floatsom who “crossed” in a shipwreck and somehow merged with the ship’s figurehead to become one herself. She is a “figurehead by day, figure of fun by night”.
It appears to be a rather organized ship with a Feast once a week followed by “the sharing”.
