Hovertech

"And so it came to pass that (the Eskatonic mystic) Diophora, lecturing to (the tyrant) Kurgari'i Alecto, spake unto her, `Wilt thou be as the hovercraft, which, so long as the terrain is easy and sure, bears its master aloft on invisible wings of false hubris, detached thereby from man and Pancreator; but, upon coming to a great and lightless abyss, fails in its boastful endeavor, and sends both itself and its  erstwhile suzerain spiraling down into the void?'"
