Holds, in Anne McCaffrey's science fiction series Dragonriders of Pern, are the residences of the bulk of the planet Pern's population. Members of specialized professions on Pern live in Crafthalls and dragonriders live in Weyrs, but for most people, the Hold is both the residence and primary social authority. As the series opens in the novel Dragonflight, there are fifteen such Major Holds, occupying the entire Northern Continent (other than the uninhabitable Arctic). These holds are listed below.
