At this turning point, Saint Dane steps in to guide the territory towards utter chaos, while Bobby and his allies attempt to stop these efforts.

"[4] The remaining five books, The Rivers of Zadaa (2005), The Quillan Games (2006), The Pilgrims of Rayne (2007), Raven Rise (2008), and The Soldiers of Halla (2009) were all originally published in hardback by Simon & Schuster.

Robert "Bobby" Pendragon is an everyday athletic junior high school student from (fictional) Stony Brook, Connecticut, located in the greater New York metropolitan area.

Most of the novels in the series are structured around a similar basic conflict: as one of Halla's ten territories reaches a crucial turning point, in which its people must make a critical global decision for their future, Saint Dane arrives, hoping to lead the people towards self-destruction, especially through cultural homogenization, social inequality, discrimination, and totalitarianism.

Bobby also comes to respect the diverse peoples of Halla, who wildly differ in their social structures, technologies, philosophies, traditions, and other cultural aspects.

Saint Dane's long-term strategy also eventually surfaces, centering on a mysterious event called "the Convergence", in which the territories' turning points all begin to coincide, potentially causing an escalating chain reaction of chaos throughout Halla.

By the ninth book, Bobby and his friends have successfully prevented the destruction of five territories, but they have failed in their fight against Saint Dane on Second Earth, Veelox, Ibara, and Quillan.

Even worse, by overrunning Second Earth, Saint Dane manages to reverse all previous Traveler victories, allowing him to establish an elitist and genocidal cult called Ravinia.
