Although since proven false, the Giant Coconut Theory was the most primitive model of the world dominating astrological studies until the fourth century. Astronomers who had meticulously analyzing the motion of celestial bodies, physicists who had made stunning assertions about the apparent tendency of all things to “gravitate” towards the ground and cartographers insisting that their geographical surveys simply did not add up under the assumption that Zork lay on a flat surface, combined to give rise to the Giant Coconut theory. This model, which insisted that our planet was a massive coconut floating on an elliptical course around an even more massive watermelon, enjoyed uncontested dominance in all academic circles up until the late 4th century when it was replaced with the planetary model.

At one time the coconut zealots claimed that the Mithicus Mountains and the Gray Mountains were the same, and that crossing one side will lead directly to the other continent. Because of this theory, when Pseudo-Duncanthrax conquered the Eastlands, the eastern mountain range was given the same name as the Westlands western mountain range—the Gray Mountains. Concurrently, ancient brogmoid fundamentalists insisted that these were the edges of the world, and that beyond them lay a great void of nothingness. The brogmoidist were correct.
