Description: When AIVAS-the Artificial Intelligence Voice Address System - was first discovered at Landing, the entire planet of Pern was awed at the knowledge
it divulged. All the history of the people of Pern was there. Dragonholders, Lord Holders and Craftmasters crowded into the tiny inner room to
learn the secrets of their beginnings. And AIVAS had other gifts to offer - stored information of old crafts that had been forgotten, of medicine, music and technology.

But the greatest promise AIVAS offered was the chance to rid Pern of Thread forever. All the great ones of Pern began the long and arduous task of
learning just how to operate the incredible plan -a plan of such daring and epic proportions that both dragons and riders would be put at risk.

ALL THE WEYRS OF PERN is a new history which follows the discoveries made at the end of THE RENEGADES OF PERN. Both stories are part of Anne McCaffrey's world-famous Chronicles of Pern.
