As they flee back to the river in one of the researchers' aircraft, they see Orlando and Fredericks being swept down the river on a leaf. As they attempt to rescue them, Renie and !Xabbu are pulled through the river gateway with them, but the two groups wind up in different simulations.

Meanwhile, in the real world outside the network, other people are being drawn into the widening Otherland mystery. Olga Pirofsky, the host of a children's net show, begins to suffer from terrible headaches. She suspects that her online activities might have something to do with it, and in the course of investigating her problem, begins to learn of the apparently net-related illness that has struck so many children (including Renie's brother.) Olga's research also draws the attention of a lawyer named Catur Ramsey, who is investigating the illness on behalf of the parents both of Orlando and Fredericks, since in the real world both teenagers have been in a coma ever since their entrance into the Otherland network.

John Wulgaru, who calls himself Dread, and whose hobbies include serial murder, has been an effective if not one hundred percent loyal employee of the incredibly wealthy Felix Jongleur, the man who heads the Grail Brotherhood (and who spends most of his time in his Egyptian simulation, wearing the guise of the god Osiris.) But in the course of killing an ex-member of the Brotherhood at Jongleur's orders, Dread has discovered the existence of the Otherland network, and has even taken over one of the sims in Renie's marooned company. As his master Jongleur is caught up in the final arrangements for the Otherland network—whose true purpose is still known only to the Brotherhood—Dread busies himself with this new and fascinating puzzle.
