Welcome to Gre'thor - the Klingon equivalent to "Hell".
This is where the souls of the dishonored go when they die
You are being ferried there on the Barge of the Dead in the waters inhabited by Kos'karii
Beware of the monster Fek'lhr, guardian of the gates of Gre'thor.

You will be directed into hell shortly, or if you are in a hurry..... Grethor
