The captain's experienced crew splits up as some take up weapons while others keep the ship on course. Several minutes of eerie silence pass as the crewmen guide the vessel through the narrow channel.
A sharp THUD breaks the silence and steals everyone's attention momentarily. Then another, on the other side of the boat. A brave crewman looks over the side for the source while others scan the trees for threats.
"Pitch!" another crewman yells, as the first stands up from looking over the side, covered in the viscous goo. Soon after a huge band of goblinkin erupt onto the banks and from the trees, armed not with weapons, but with casks of pitch raining down on the ship, inside and out.
The captain stands stunned in the center of the ship's deck, seemingly unable to move. "They're gonna turn 'er to cinders," he says, defeated.
