Ruins of a Duergar city, was home to the Nexus Encephalon and its thralls. Just beyond the ruined city is the ancient ziggurat Velkrazar.
The ruined city of Uldrazim is a long-abandoned Duergar city with a castle-fort is stationed in the center of a stone brick city is all settled behind a 20 foot high wall. Upon the detonation of the Devastation Orb of Earth, the exterior wall was heavily damaged by the tremors and falling boulders, and a tower in the castle was razed. To the north is the trades district, with blacksmiths, apothecaries, and libraries. Specifically, the Granite Codex is here, and is used by the Nexus Encephalon as one of several repositories for their stolen texts and histories on world religions, the Deities, and the Ends of Empyrean. To the south is the residential district, where most of the Illithid population has taken up residence, converting homes into tadpole spawning grounds and holding areas for prisoners and slaves. The castle is in the center, and is used as another stronghold of stolen texts, as well as all the magical artifacts.
Varok Hold: Castle-fort in the center of the city. It was notably seen to have 2 large towers which rose high above the rest of Uldrazim. When the city was hit by the Devastation Orb, the tallest tower fell down the eastern side, the back of the castle and crashed into the grounds below. In the castle ground are the amassed treasure and artifacts gathered by this colony.
