World Brain

The World Brain was the fully grown dhuryam that the Yuuzhan Vong used in Vongforming Coruscant into Yuuzhan'tar. Jacen Solo was part of the group of slaves that were assigned to take orders from it, so that the Shaper caste could select which of the twelve dhuryam was to be the World Brain. Jacen aided his fellow slaves, and the dhuryam was aided for it. The dhuryam was ultimately chosen, however, when Jacen killed all the other ones. The dhuryam was placed in the Old Republic Senate Building, where it grew to it's full size. Jacen later convinced the World Brain to sabotage the Vongforming in small, irritating ways in an attempt to convince the Yuuzhan Vong to compromise with other species. The World Brain did exactly that: causing damuteks to melt, an itching fungus to release on the arrival of Supreme Overlord Shimrra, and a swarm of stinkbugs to overpopulate. Shimrra eventually gained control over the World Brain prior to the Liberation of Coruscant, but Jacen convinced it to help the Galactic Alliance groud forces. The World Brain was remained as part of the new Coruscant.
