A decade has passed since the Age of Heroes began. The city of Tyr has broken free of tyranny, though turmoil still holds the world in its merciless grip. The Dragon King lies dead, earthquakes rock the land, and revolution spreads like wildfire across the Tyr Region. Giant rifts pierce this once impenetrable land: far to the north, the alien thri-kreen empire quickens, sensing its opportunity to invade. And to the south, in the obsidian wasteland, the ground stirs with the emergence of the undead....

Welcome to a world where metal is scarce, gods don't exist, and psionic powers abide in all living creatures! This significantly expanded and revised set contains everything you need to adventure across the burning lands of Athas.
