What is the plot for Antrax?

Answer 1

The voyage to find the lost magic takes the companions to the continent of Parkasia. Here, they are split up, and Walker, despite all his plans and his enormous power, finds himself caught and trapped by an unseen force, a supercomputer built by the ancient humans. Antrax was created to store data and information from its time and it is given a duty, an order to protect the information that it holds. However, when the Great War broke out, the last of its creators returned, and gave Antrax its final task: protect the information at all costs, no matter what the price. Antrax then began to build its own arsenal of defence mechanisms: lasers and Creepers.

Above Castledown, the crew of the Jerle Shannara find themselves besieged by evil forces, and the Ilse Witch confronts the Druid's protégé, Bek Ohmsford, who claims that she is actually Grianne Ohmsford, and that he is the brother she last saw as an infant - now a young man who carries the Sword of Shannara and wields the magic of the wishsong.

Meanwhile, Walker realises that the 'magic' they have been searching for is actually the science of the Old World, stored on Antrax, which could be used to rebuild society with new technology. But there is no practical way to access this information, so Walker chooses to destroy the power-hungry computer, which is quickly becoming a danger to the whole world. However, he is mortally wounded in the process. He dies soon after.

It is believed that Antrax was in fact initially known as Oronyx Experimental and appears in The Elves of Cintra.
