The Druid Histories, kept in Paranor, are magical tomes written and maintained by the Druids. They chronicle the known history of the Old World and New World, with particular focus on magical, supernatural, and mystical phenomena. The tomes are held in the library in Paranor in a special crypt created by Allanon. Before that, Bremen gave the Druids' librarian a bag of magic powder with which to render the Histories invisible to prevent them from being seized by Skull Bearers.
