On the southern end of Kalimdor, a forgotten civilization hides behind otherworldly technology, forged by the Titans to protect the great machinery of Reorigination. The tol'vir, great protectors of the ancient machinery, stand stalwart against the corruption and fighting. Some tol'vir have succumbed to the aqir long ago, but the civilization remained unknown to the whole of Azeroth. After Deathwing's violent breach from the Maelstrom changed the world forever, the resulting chaos broke the shield that hid Uldum and revealed its sands. Now, Deathwing and his allies fight to corrupt the tol'vir and bring chaos to Uldum and beyond.
Uldum continued the Cataclysm zone progression by moving you from the rocky, subterranean world of Deepholm into an open-air desert, a welcome change for the claustrophobic adventurer. Giant pyramids, monumental statues, and an Egyptian motif made Uldum one of the most beautiful and well-realized zones in Cataclysm. As players embarked on two very distinct quest lines, the story of Uldum unfolded as the forces of the wind broke the Skywall through the desert sky and into Azeroth's realm. On the other side of the zone, players were sent on a sprawling adventure with fan favorite Harrison Jones on a bumbling expedition to figure out the purpose of the Obelisks of Uldum and get into some wacky trouble.
This is going to be the most controversial of the Cataclysm post-mortems. I can feel it. Uldum was a zone that people either loved or hated during the content push to 85. We are going to try to keep it civil.
