William Randolph Flathead, also known as "Citizen Flathead" was a publishing giant sometime before the fall of the Empire in 883 GUE. A Frobozz Magic Toboggan with a faded image of a blooming morgia plant and the name "Morgiabud" may have once belonged to him. If so, his one-person sled was the once used by the First Dungeon Master to slide down a slope in the Gray Mountains.
