The Arrival on Eelong and the Mysterious Plague
Bobby Pendragon and fellow Traveler Loor arrive on Eelong, a dense, swampy jungle world with the cat-like Grall and ape-like Klee. Press, the Eelong Traveler, tells them about a terrible plague killing the Klee. The Grall seem immune but their society and ecosystem are also suffering. Press explains this plague is new, and he suspects Saint Dane, though how he is involved is unclear. Bobby and Loor start investigating the disease's source and spread.
The Hunt for the Cure and Saint Dane's Taunts
As Bobby and Loor investigate, they learn the plague is a bioweapon made by Saint Dane. The villain appears to Bobby, enjoying the chaos and saying the antidote is on another territory. This gives Bobby a difficult choice: Traveler rules strictly forbid moving anything, especially biological material, between territories, which could upset Halla's balance. But if Bobby follows the rules, the Klee will die out. Saint Dane wants Bobby to break the rules, corrupting his role as a Traveler and possibly destabilizing Halla.
A Desperate Plan: Seeking the Antidote on Earth
With the Klee facing extinction, Bobby decides to break the Traveler rules. He determines that the only way to save Eelong is to get the antidote from Second Earth, his home. This choice is dangerous for him and all of Halla, as changing the natural order of territories could have unknown and terrible results. He knows if he fails, or if other Travelers find out, he could lose his Traveler status, or worse, cause lasting damage to existence. Loor, though unsure, supports Bobby's choice, understanding how serious the situation is.
The Journey to Second Earth and Mark and Courtney's Role
Bobby makes the dangerous jump to Second Earth, arriving when his friends, Mark Dimond and Courtney Chetwynde, are facing their own problems. He explains Eelong's serious situation and the need for a specific antidote. Mark, with his scientific mind, and Courtney, with her resourcefulness, quickly understand the urgency. They begin to research and get the biological agent needed to cure the Klee. This task is hard because they must do it secretly, without drawing attention to Bobby or their unusual mission, while dealing with their own daily lives.
The Antidote's Creation and the Race Against Time
Mark and Courtney use their knowledge and contacts to make the needed antidote. They face several problems, like finding rare chemicals and doing experiments without a proper lab. Meanwhile, Bobby, back on Eelong, sees the Klee continue to suffer. Time is running out, and more are dying. He talks to Mark and Courtney through the flumes, updating them on the Klee's worsening condition and urging them to hurry. All three are under great pressure, as their plan's success depends on acting quickly and secretly.
The Return to Eelong and the Distribution of the Cure
With the antidote made, Bobby returns to Eelong with the life-saving substance. The challenge is now to give it to the many scattered Klee, many of whom are very sick. He, Loor, and Press work tirelessly, traveling through the dangerous jungle, giving the antidote to the sick. The Klee are at first cautious, but as they see others recover, hope spreads. The process is slow and hard, needing constant watch and careful planning to reach as many Klee as possible before it is too late.
Saint Dane's Final Gambit and the Grall's Betrayal
As the Klee start to recover, Saint Dane makes his final move. He reveals the plague was meant not just to kill the Klee, but to start a fight between the Grall and the Klee. He had secretly given the Grall a 'cure' that, while seeming harmless, was actually a slow poison, meant to further destabilize the territory. Also, he made the Grall believe the Klee's recovery was a threat to their power, encouraging them to attack the Klee. This twist forces Bobby to deal with both the plague and the growing war between the two species.
The Conflict and the Truth Revealed to the Grall
A full war breaks out between the Grall and the Klee. Bobby, Loor, and Press are caught in the middle, trying to protect the recovering Klee while also trying to reason with the Grall. They must convince the Grall they have been tricked by Saint Dane and that the 'cure' they got is actually a poison. This is a huge task, as the Grall are very proud and distrustful. Through talking and showing the antidote's power, they slowly start to change things, revealing Saint Dane's hidden lies.
The Aftermath and the Lingering Consequences
The Klee are saved, and the Grall eventually understand Saint Dane's trick, stopping the war. But Eelong is damaged. The Klee population is much smaller, and the Grall must now deal with their own slow poison, though a milder antidote can be made. Bobby, Loor, and Press think about the high cost of Saint Dane's actions and the hard choices they made. Bobby knows his act of bringing the antidote from Second Earth has changed Halla's balance and that other Travelers will find out, leading to serious results.
Bobby's Reckoning and the Future of the Travelers
Bobby carries the weight of his decision. He knows he broke a main Traveler rule, but he believes it was the only way to save Eelong. He understands this act will have effects, not just for him but possibly for the entire Traveler order and Halla's stability. While he regrets breaking the rules, he does not regret saving the Klee. This experience strengthens his resolve as a Traveler, making him question strict rule-following when faced with clear moral needs. The future of the Travelers and the fight against Saint Dane now seems more complex and morally unclear than ever.
