Qahsa Qahsas were an organic creation of the Yuuzhan Vong and served as a type of computer . Overview . These creatures were capable of storing the knowledge of the Yuuzhan Vong empire ' s Shapers thus serving as living memory banks . They came in a variety of sizes from personal devices to databases for worldships . A qahsa was accessed through the use of a cognition hood . They were capable of being grown quickly on demand with portable versions of the device being present . It was possible to place a lock on the qahsa that was coded - genetically that was only capable of opening to an incredibly complex biochemical key . The information within these computers was maintained in increasingly dense cortices with each successive one being accessed only by an experienced individual . The Shaper caste maintained seven cortices which surrounded the ultimate eighth cortex . Master Shapers were capable of accessing data beyond the fifth cortex while Shaper Adept ' s were restricted to the fifth . Being analogous to computers or memory banks , qahsas stored information on history , techniques , and other past events . The data within a qahsa was believed among the Yuuzhan Vong to have been bestowed upon them by the Yun ' o . Those that sought new information through innovation suffered from being labeled as heretics . Genetic splicer s were used to access them . A special type of qahsa was the Qang qahsa which held the eight Shaping protocol s History . During the Yuuzhan Vong War , Jedi Klin - Fa Gi and Bey Gandan attempted to follow Wurth Skidder ' s example and pose as slaves . They were later taken aboard a Shapers vessel before the galaxy became aware of that caste . At the time , they were assigned to tending to one of the living information systems known as a qahsa . While the Shaper sects were assigned on creating anti - Jedi weaponry , they encoded data inside a qahsa that was to be delivered to Warmaster Tsavong Lah . It was at that point that Klin - Fa Gi and Bey Gandan sabotaged the ship in an attempt to recover the qahsa . However , as it was coded - genetically , she was incapable of opening it which led to her infiltrating Wayland to find a method of opening the biot . Onboard the worldship Baanu Miir , Shaper Adept Nen Yim attempted to consult the qahsa ' s knowledge to determine a means of healing the dying Rikyam brain of the ancient vessel . However , she discovered that the knowledge was insufficient for the task and attempted to consult the Qang Qahsa ' s database only to discover that the Eighth Cortex was nearly empty of knowledge . When Tahiri Veila , Nen Yim , Corran Horn , Harrar and Nom Anor went to Zonama Sekot in 28 ABY , Nen Yim brought along a qahsa to gather information . The qahsas also contained protocols in case Zonama Sekot proved to be a danger . Nom Anor used these protocols to try and destroy Zonama Sekot . Nen Yim later made use of a qahsa during her study of the living planet of Zonama Sekot . After studying the native life , she discovered many organisms that were similar to ancient Yuuzhan ' tar which was later proved by the existence of relatives of the lim tree ' s which were extinct with only their blueprints present in the qahsas . In order to test her theory about The Force , Nen Yim used a newly grown qahsa to link her mind with that of Zonama Sekot thus discovering its secret as being a child of their ancient homeworld . She was killed for her knowledge by Yu ' shaa , who was really Nom Anor , who in turn used one of her qahsa ' s to release a replicative disease onto Zonama Sekot in order to destroy it .
