All the Weyrs of Pern is a novel in Anne McCaffrey's Dragonriders of Pern series. It features a computer called AIVAS (Artificial Intelligence Voice Address System) which lead Pern in an attempt to destroy Thread forever. During this time, Pern regained much technology that was lost to the colonists in early attempts to survive Threadfall. Among this was the knowledge of electricity, surgery, printing, and a few other useful tools, which led to the creation of new Crafthalls, notably the Print Hall. The knowledge of this technology and its origins was transmitted by Aivas (the Pernese changed the initials into a name) to the Pernese. Aivas itself had been programmed to speak with a masculine-analogue, inquisitive, somewhat humorous personality, which gave the impression of a lighthearted counselor.
Eventually, the Red Star is thrown into a more distant orbit, dooming the coming Threadfall to be the last of its kind to fall on Pern. Masterharper Robinton is killed mysteriously when visiting AIVAS; at the same moment, Aivas also dies. Those who perceived the sentient, intelligent computer as an "Abomination" take this as fuel for their prejudice, claiming that Robinton killed Aivas while trying to discover what evil it was plotting, only to die himself before passing that knowledge on. This claim, and its proponents, cause trouble in "The Skies of Pern".
