Pern was originally a Terran colony, but the Turns (years) of fighting the voracious spore Thread, which falls from the skies at regular intervals, have eroded the memory of Pern's origins to mere legend. The level of technology is medieval, generally speaking. The Pernese protection from Thread are the dragons of Pern and their riders, who live in the Weyrs. Most of Pern's population lives in the Holds or the Crafthalls. In order to survive, Pern's inhabitants must cooperate, so armed conflict and wandering about the planet are extremely rare, if not all but abolished. A secure family and home is the most common background.
PernMUSH does not recognize the AIVAS plot presented in several of the more recently published books, so there is no 'rediscovering' of technology in our game. However in the turns since the timeframe of the books, the strictures against women have eased and women can be Lady Holders, CraftMasters etc and can ride any colour, but bronze.
