This yahoo group will be the developing grounds for a campaign setting that I am designing, called Tale of the Twin Suns. The world is steeped in ancient arcane magics. A new type of power for casting magic from your very essence, your spirit, is in its infancy. Divine magic is here as well, it is more ancient than arcane magic and much safer than spirit casting.
Several new races are being developed for the world, and some from the PHB are being left out. Only two or three character classes from the PHB will be present that are unmodified. Other classes that bear the same name of phb are reworked. Also a great deal of the classes have been reworked and renamed.
The goal of this group is to free up as much of the campaign for Open Game Content and to refine aspects of it through playtesting. Most of this material comes from the back of my mind. I do my best work when I'm trying to fall asleep. There are some elements from other books here, but what is used is already Open Game Content.
