Pern is the third planet of the Rukbat system in the Sagittarius sector. It is a colony world which has lost contact with 'Mother Earth' due to periodic attacks from an organism called Thread, which devours all organic material it comes into contact with. To counter Thread, the original Pernese colonists -- back when they still had the skills -- modified an indigenous life-form to create Dragons -- so named for the mythical beasts they resemble. Modern day Pern (as depicted in most of the books)as played on Dragonsfire, has lost many of the skills originally brought with the colonists and can probably be best described as a pre-industrial society. Pern is the home of Dragons, their riders, Fire Lizards and various other people as depicted in Anne McCaffrey's Dragonriders of Pern series and related books. These characters may be of a variety of different professions or 'Halls'. These Halls include Harpers, Healers, Weavers, Smiths, Dragon Riders and a variety of others.

Very little of Pern is actually inhabited, the map below shows the inhabited regions.
