Roleplay within a Pernese theme works because the world is so well fleshed-out. In her books, and through the Dragonlover's Guide, Anne McCaffrey provides a wealth of information on the details of her world. We know a great deal about animals, plants, minerals, terrain, moons, healing techniques, the worth of Pernese money, and what kinds of people inhabit the Holds, Halls, and Weyrs of Pern. The base of information is supplemented by the research and imaginations of SouCon's players in such ways as choosing where timezones fall or which Pernese places will come alive through our roleplay.
