Azeroth's native elementals wreaked havoc across the world while they were under the influence of the Old Gods.

To keep Azeroth safe from these threats, the titans imprisoned the Old Gods underground and banished the savage elementals to the titan-constructed Elemental Plane, a secure dominion where the elementals could dwell without harming Azeroth.

Four domains were created within this primordial realm to serve as ideal environments for each type of elemental. For ages since, the elementals of air, water, earth, and fire have engaged in endless strife with each other, waging titanic battles in the confines of their realm. One of the Elemental Plane's domains, a vast ocean known as the Abyssal Maw, is home to the water elementals. Legend says that Neptulon the Tidehunter, the powerful being who rules over the aquatic realm, possesses a potent weapon that allows its owner to control the very seas of Azeroth. Thus far, the artifact has remained secure inside the water elementals' domain... but that will soon change.

Within Deepholm, the domain of the earth elementals, the malefic Dragon Aspect Deathwing is on the verge of executing a catastrophic act: to burst forth from the Elemental Plane into Azeroth. Doing so will ravage the surface of the world and breach the barrier that separates Azeroth from the elementals' realm. Whether Neptulon and his subjects have entered into an alliance with Deathwing remains unknown. Regardless, if Deathwing's actions create an opening into the Abyssal Maw, nefarious and honorable factions alike will seek out the fabled weapon carried by Neptulon. Whoever secures the artifact will have control over the world's seas, a power that perhaps no one, not even members of the Horde or the Alliance, should possess.

As with Uldaman and Ulduar, Uldum houses one of only a few of the known titan constructions, the existence of which predates that of mortal life on Azeroth. For years historians have explored southern Kalimdor for a means of entry into this ancient titan land, searching for more evidence of Azeroth's origins. But the Cataclysm will change everything, for the façade behind which Uldum has been tucked for millennia will be ruptured, leaving powerful mysteries vulnerable to discovery by the bravest, smartest, or perhaps even most brutal explorers.


The Halls of Origination in Uldum is a level-85 five-player dungeon available in World of Warcraft: Cataclysm, featuring an unparalleled journey through the timeless titan construction and seven unique boss fights. Hidden deep within its halls lies an ancient treasure that, if placed in the wrong hands, could endanger all life on Azeroth. Should players survive the perils of Uldum, they will be called to help Brann Bronzebeard unlock the mysteries within these treacherous titan halls and protect the titans' ancient secrets.

Entering the Halls
You will immediately learn the gravity of your situation in the Maker's Overlook when stumbling over the bodies of those who have entered the Halls of Origination before you, seeking power... and failing. Those who survive beyond the entrance of these ancient corridors will be greeted by Brann Bronzebeard just outside the dungeon's transport system to the upper reaches. It will require more than the guidance of Brann to advance upward, however, as the secrets of these halls must first be unlocked.


Chamber of Prophecy
The column-strewn Chamber of Prophecy is truly a testament of time. In a room adorned with the relics of an ancient culture, two arks await investigation, protected by ever-faithful servants. Those who meddle with the titan relics must answer to Temple Guardian Anhuur, the overseer of this chamber and a master of holy magic and devastating hymns.

Tomb of the Earthrager
Across from the Chamber of Prophecy and just outside the dungeon's walls lies the Tomb of the Earthrager, entrenched within a pyramid sun-scorched and bombarded with sandstorms. Littered with the bones of the long deceased, the tomb waits to collect more unprepared victims. It is, after all, the resting place of Earthrager Ptah. Those who disturb his tomb disrupt an eerily quiet place before Ptah shakes the ground beneath you in a Tumultuous Earthstorm, bringing to life the weathered bones of the deceased and unearthing vile Scarabs.

The Vault of Lights
With walls weighted by priceless titan artifacts, the Vault of Lights will serve as a chamber of punishment for your intrusion. Anraphet, a haunting statue of titan composition, awakens to serve his fellow keepers and eradicate all mortals who enter. Make no mistake: his long slumber will not prevent him from showing absolute wrath.

Seats of the Keepers
Survivors of the halls' depths will gain access to the upper reaches. With help from Brann Bronzebeard, you must uncover the mysteries of Uldum. Your journey will lead you to areas of ultimate consequence: the Seats of Magic, Life, Chaos, and Radiance. Here you will be confronted by the construct of magic Isiset, construct of life Ammunae, construct of chaos Setesh, and construct of radiance Rajh. You will be tested by these constructs of Uldum, who will not easily give up their thrones or the secrets of the titans.

Only by exploring Uldum's Halls of Origination in World of Warcraft: Cataclysm will you have a chance to uncover their dangerous powers, and perhaps even the mysteries behind the origins of life on Azeroth.
