are listed in fuller detail below. Acolyte: A person native to some territory who is chosen by that territory's Traveler as his or her own personal aid, including the receiver and keeper of that Traveler's journals. The Convergence: The chain-reaction event toward which Saint Dane manipulates Halla in which all the territories reach critical turning points simultaneously, spiraling them all toward total chaos. Dado (): Any humanoid robot member of the security and police forces of the monopolistic mega-corporation Blok (on Quillan) and which Saint Dane later mass-produces on Third Earth and elsewhere into his own personal armies. The name originates from the acronym D.A.D.O. (Dimond Alpha Digital Organization), a First Earth corporation that produces forge technology. Flume: Any of the tunnels that link each one of the territories with the other nine. At the entrance to a flume, a Traveler must speak the name of a territory, causing the flume to writhe to life, turning its rock walls into transparent crystal, emanating a jumble of pleasant musical notes, and lifting and pulling the Traveler gently into the flume towards the spoken destination. Forge: A shapeshifting, voice-activated technology patented by D.A.D.O. (though seemingly actually invented in Third Earth and stolen from that territory by Saint Dane) consisting of an object with flexible, elastic skin that can change into various simple geometric forms including a pyramid, a cube, and a sphere. Apparently, it is the main technology inside the robotic bodies of dados. Gar: The human race on Eelong, though the gar of Eelong tend to be of smaller stature than the humans of Earth and most are not educated or civilized, largely kept as slaves in klee society. Halla: The multiverse, including every person, thing, time, and territory there ever was. Press Tilton describes it also as "what separates order from chaos." It includes at least seven worlds with human beings; Halla, however, is also physically divided (by Saint Dane's flumes) into ten distinct territories. The Jakills : a rebellious youth subculture of seventeen critically thinking teenagers on the island territory Ibara, including Loque, Krayven, Twig, and their leader, Siry Remudi, who help Bobby Pendragon seek the world beyond their island's oceanic boundaries. Klee: the dominant, sapient species of Eelong, who have bipedal feline bodies and live in treetop village societies. Pentagram: The symbol of a five-pointed star made by interlocking lines, used by the spirits of Solara to designate
