The Uldir complex

Uldir raid portal

Uldir (pronounced "OOL-deer") is the first raid of Battle for Azeroth, situated in Nazmir. It is entered from the Heart of Darkness, with the door being in the southeastern part of the Altar of Rot.

Uldir was a titan research and quarantine facility where the titans conducted experiments on the Old Gods and dissected them to try to understand them. The titans' plan was to kill the Old Gods without ending their host: Azeroth.^[1] They ended up accidentally creating something that could potentially wipe out all life on the planet, a fifth Old God named G'huun. It was locked away within Uldir via three seals, each located within the pyramids of Atul'Aman, Nazwatha, and Dazar'alor. With the fall of the last seal, nothing now prevents G'huun from spreading his rot and decay across the world.^[2]

During the Fourth War, a group of Horde adventurers entered Uldir to slay G'huun before he could break free.^[3] After the end of the war, the facility returned to a dormant state, and the residual Old God corruption inside went back down within acceptable parameters.^[4]

The Alliance travels through Uldir alongside Brann Bronzebeard, while the Horde is accompanied by Princess Talanji.

Adventure Guide

Millennia ago, seeking to understand the nature of their eternal foe, the titans constructed this sprawling underground facility to research and quarantine captured specimens. They hoped that by studying the void energy that bound the Old Gods, probing it for weaknesses and reactions, they could find some way to neutralize it. They were horribly, horribly wrong. The facility was sealed away so that the horrors within would never be unleashed upon Azeroth. But now those seals have broken...

Crimson Descent

The remnants of old experiments gone awry litter the lower halls of Uldir, as a dark power stirs within the depths.

Heart of Corruption

In foul pits, far beneath the halls of Uldir, the source of the corruption that has befallen Zandalar awaits.
