Barge of the Dead

From Memory Alpha, the free Star Trek reference

For the VOY episode of the same name, see "Barge of the Dead".

The Barge of the Dead is a mythological Klingon ship which ferries the dishonored souls of the dead to Gre'thor, captained by Kortar (also known as "Kotar"), the first Klingon. When Kortar became more powerful than the gods who created him, he destroyed them, and, as punishment, he was condemned to ferry the souls of the dishonored.

Along the Barge's path, the kos'karii try to lure the dead off the Barge, like the sirens of ancient Greek mythology. (VOY: "Barge of the Dead")
