KEEPER (TERRIS): Often used loosely as another term for a Feruchemist. The Keepers were actually an organization of Feruchemists dedicated to discovering, then memorizing, all of the knowledge and religions that existed before the Ascension. The Lord Ruler hunted them to near-extinction, forcing them to remain hidden. After the Collapse, they began teaching and revealing their knowledge. However, they were attacked by the Inquisitors about the time of the siege of Luthadel, and are all presumed dead, save Sazed.
