The Last Continent

It's the Discworld's last continent and it's going to die in a few days, except...Who is this hero striding across the red desert? Sheep shearer, beer drinker, bush ranger, and someone who'll even eat a Meat Pie Floater when he's sober. A man in a hat whose luggage follows him on little legs. Yes, it's Rincewind, the inept wizard who can't even spell wizard. He's the only hero left. Still...no worries, eh?
