Susan Van Camp created the world background in the 1980's. She published the Dragon Storm RPG in 1994. The game was published in 1996. The Second Edition came out in 2011.
Here are some additional Thoughts of hers on the world and the game.
Throughout the development I (Mark Harmon) have been honored to help. Due to the game theory Sue developed, I have had a chance to make additions to the world. I also married the Game Designer. Everything has perks.
