The renegade crew of an airship is almost reaching port when a massive sight looms in the distance: an impossibly huge giant rises out of the valley and slowly lumbers towards their destination port. One of the four arms of the monstrosity reaches up and in a single swoop, utterly smashes the port into nothing, but a crater. Without even losing a stride, the colossus takes another slow, thundering stride towards it's next destination: another port far in the distance. The crew are left with an impossibly daunting task: somehow, board that heaving hunk of metal and put a stop to it's reign of terror before the entire continent is turned into a lifeless field of impact zones.
