Why Is the World Round Anyway?

Fred had read something in that evening's Daily Expatiator regarding the disappearance of a brilliant Lecturer by the name or Professor Casa Blanca from the University of Marrakesh. Blanca had just formulated several secret theories on the reasons for global roundness. His vanishing had left the academic world screaming: WHY IS THE WORLD ROUND ANYWAY?

So it was with a strange feeling that Fred retired to bed that night, as if he were about to experience a bout of deja vu, and with the vague notion that he was about to set off on another adventure game!
