"For thousands of years, the Tablelands have remained untouched: its politics frozen in a delicate stalemate; its life in a balance even more delicate. It is true that the Dragon Kings amused themselves with their petty wars, rattling sabers to punctuate the passing of ages. It is true, that occasionally, another city would be swallowed by the wastes."
"But there were no surprises. The Dragon Kings steered everything from their omnipotent perches, content in their superiority, but ever thirsting for challenge."
"All that has changed. The Tablelands have been thrown into turmoil, the likes of which have not been seen since times forgotten. The Dragon Kings have been thrown into confusion, grasping for the tedium they so recently lamented."
"And yet, I fear that the worst is yet to come. Change is in the air, and change has never come gently to Athas." Excerpted from a letter from Oronis
Dark Sun 3 is an updated rules set for D&D 3.5, and contains everything you'll need to play in the Dark Sun world through the non-epic levels. This is a rules conversion only; in order to fully enjoy the Dark Sun setting, you should have access to the Wanderer's Journal or the Wanderer's Chronicle, which are the setting books published in the first and second Dark Sun boxed sets, respectively. If you do not have either boxed set, they can be purchased from RPGNow! as PDF documents.
