Crafters are the skilled artisans of Pern. For every need, there is a Crafter, a trained professional, who is able to advise, teach, and solve problems. The Harper's oversee music, teaching, history, politics and archiving. The Healers take care of the sick and injured, prepare lotions and balms, and are involved with the hygiene of the population. Smiths create mechanical items of need, such as Flamethrowers, Starsmiths watch the heavens and teach navigation. Vintners brew wine and beers, and Woodsmiths oversee the forests, prepare wood and make items of furniture. Weavers and Tailors make furnishings and clothes, and Tanners prepare leather for straps, saddles, and flying leathers. Bakers see to the nutrition of the population, and introduce new ways of cooking, whereas the farmers oversee the crops, testing soil and recommending various harvests. Beastcrafters look after the health of animals, and see to effective breeding programs for improving the livestock. Seacraft navigate the seas, transporting items from one continent to another, and providing food from the oceans.

Crafts contribute their services, skills and goods to the Weyr that protects them, in return for protection against Threadfall, as well as to the Holds of Pern, from which they receive food, and raw materials in order to sustain their Crafthalls.

Each Crafthall has a CraftMaster, the person in charge of the Craft, the CraftSecond, or second in command, and generally an Apprentice Master who teaches the new members of the Craft.
