That answers some things, but its not an airship. its an actual ship. The quest literally takes me to a location on the ship and there is a red circle on the map like I'm supposed to be there, but there are no NPCs to talk to and nowhere to go. I've google searched the quest a ton and they don't give me any info besides what I already know: that I have to talk to this YOUNG EXECUTIONER, but he's in the area of the ship that I can't go to for some stupid reason.
