Circa 200 years after the Three MATA Brothers left their bunker to reassert MATACORP dominance over what remained of the destroyed planet, a hobbyist cartographer, Mavic Pengellan, born to an affluent penguin family in one of the Penguin Protectorates, would create his depiction of the world (with a fair amount of creative liberties).
His work was immediately suppressed in favor of the official MATACORP map of the world.
Pengellan's map however remains as the closest approximation of the world, used by wandering techno-mages.
The earth is fat.
