Well of the World Brain
this was the name of the deep, yorik-coral cavern which was grown by the Yuuzhan Vong to hold the mature dhuryam which would control the planet Coruscant, which they had renamed Yuuzhan'tar, some twenty-eight years after the Battle of Endor. The Well, formed from the hollowed-out remains of the Galactic Senate Rotunda site, was protected by a series of defenses, the least of which was a cadre' of Yuuzhan Vong warriors protecting the entrance. In essence, the Well of the World Brain was a huge skull, shaped to protect and contain the World Brain. The foremost defensive mechanism protecting the Well was an intricate hedge-maze, grown from heavy trees which produced thorns up to a half-meter in length. The thorns produced a deadly neurotoxin, and the tunnels which were formed by the branches were almost impervious to blaster fire and explosives. Each passage in the maze was twenty meters high and thirty meters wide, and around almost every corner was a place where Yuuzhan Vong warriors could ambush unsuspecting intruders. The trees which formed the maze completely enclosed the space, so the pattern of the maze was impossible to discern from above. Only the Master Shaper, Ch'Gang Hool, and the Warmaster, Tsavong Lah, were permitted access to the Well without an escort. However, Jacen Solo managed to reach the Well with Ganner Rhysode, on the pretense that he needed to commune with the World Brain in order to ensure Ganner's sacrifice would be accepted by the True Gods. Ganner gave his life protecting Jacen, who used the little time he had alone with the World Brain to strike a deal with it. Hidden within the Well was a coralcraft designed for Nom Anor, who had bribed a minor Shaper to create it and hide in in the Well. This provided Nom Anor wth an escape vehicle, should he ever have to flee Coruscant in a hurry.
