Sea of the Dead

The Sea of the Damned or Sea of the Dead seems to be a body of water with unknown size, which is not located inside the Sea of Thieves, nor behind the The Devil's Shroud. The only place where Players can see the Sea of the Damned is from the Ferry of the Damned which seems to sail on it. From there, it appears to be mostly dark, but also has one or more islands (though only seen in reflections). During the Ghost Fleet event, Flameheart also mentions that his fleet of ghost galleons are provided and come from the sea of the damned.

There are also mentions for "land of the dead" where the Ghost of Graymarrow and other ghosts come from. The information is so vague about the land of the dead that it doesnt deserve its own page.
