Dark Sun Boxed Set

From the publisher: A once civilized paradise, Athas, was based on awesome mental powers and the power of its wizard kings. Then the world became a desert filled with strangely twisted dwarves, elves and super-intelligent dragons. Now humans control all the cities and human magic is stripping the environment of its life force. The Dark Sun campaign set introduces players to a savage world of magical suppression and decadent sorcerer-kings.
