The major protagonists, now gathered together on board the submarine, are menaced by the Leviathan, a giant, pyramid-shaped single-cell sea monster that has been growing in size for hundreds of millions of years. The over-the-top nature of this encounter leads some of the characters to question whether they are merely characters in a book. This metafictional note is swiftly rejected (or ignored) as they turn their attention to the monster again. The threat is neutralized by offering up their onboard computer as something for the creature to communicate with to ease its loneliness. Finally Hagbard managed to defeat the Illuminati Primi and went to Alpha Centauri in 1999.
