The later material displayed a penchant for humor, often at the cost of breaking the mood. The edeinos of the Living Lands proved a popular target, transforming to other realities and becoming among other things "Skippy the Edeinos" (who in the campaign setting came complete with an action figure), a Nile Empire "Rocket Ranger" named Captain Verdigris, and an Elvis impersonator. Supplements such as "The High Lords Guide to the Possibility Wars" went so far as to address this issue and advise readers to read the original material on edeinos to make them more dangerous/serious and ignore the trend WEG had itself established. The Nile Empire also often slipped from the genre of pulp heroes into outright self-referential parody. For example, Nile Empire ninja engaged in elaborate martial art moves and high-pitched battle cries, compared to their stealthy Nippon Tech counterparts who would mock them. Scene titles in the published adventures were often elaborate puns, and there was a "Five Realms" role-playing game-within-the-game where the author Jeff Mills was a parody of game designer Greg Gorden, and who eventually went on to help save the world in the final published adventure, "War's End".
