The story began with a group of talented misfits from the Galactic Milieu of 2110 A.D. who passed through a time portal, hoping to find an idyllic world six million years ago in Earth's Pliocene Epoch. Instead, they encountered two exiled alien races—the knightly Tanu, who had made slaves of the time travelers,and the dwarfish Firvulag, fierce rivals of the Tanu. At the end of The Golden Torc, one of the humans, Felice Landry, engineered a stunning cataclysm, a flood that destroyed the Tanu capital and put an end to that race's domination of Pliocene Europe.

In The Nonbom King, Aiken Drum, a young human with awesome mental powers, manages to usurp the Tanu throne. Aiken faces opposition from human-hating Tanu, from free humans who mistrust his fantastic mind-powers, from the madwoman Felice, who has vowed to destroy him, and from the revitalized Firvulag, who now greatly out-number the Tanu-human coalition that Aiken has patched together. Aiken's efforts to retain his throne are complicated by the appearance of a new menace posed by survivors of the Metapsychic Rebellion of 2083, who, for the past 27 years, lived quietly in North America. Now these powerful humans, led by Marc Remillard, who almost succeeded in destroying the benevolent Galactic Milieu, seek to take advantage of the chaos in King Aiken's Many-Colored Land in order to seize control of the time-portal.  The Nonborn King features the same blend of adventure, rich pageantry, humor, and fantastic eroticism that characterized The Many-Colored Land and The Golden Torc.
