Korizath

The Abyssal City of Korizath was a city within the Infernal Depths of Nezperdia, the dimension of fire and home of Zalgo. Korizath was built by the Mindmages and Hecknights and ruled by Jamminus Rex, the mad immortal god-king of the city. The city, despite resistance from the creatures of the realm such as the Swine-Men of Nezperdia, the Great Spirits of Ash, and the Magma Cube infestation, Jamminus led the Hecknights and Mindmages to build the city, which survived under the brutal environment and regime.

Many years after the founding of the city, the Korizathian Mindmages constructed a portal to the Mundane World. The other side of the portal ended up in the uncivilized Northern Regions. Scarred and hardened by the world they came from, the forces of Korizath conquered the North easily.

The Towers
Three towers were constructed in Korizath and dominated the skyline.

The Black Tower housed Jamminus Rex and the Altar of Zalgo, which was used for public sacrifices.

The Red Tower was used by the Korizathian Mindmages for enchantment and potion brewing, which allowed the forces of Korizath to obliterate resistance of the frozen north of the Mundane World and conquer it.

The White Tower was not actually located within Korizath, but was the main outpost of the Hecknights in the North.

Architecture
The main defining feature of Korizath was its open-air "ribcage" streets. The structures prevented the Magma cubes native to the region from infesting the streets while also allowing residents to view the scenery. The Cult of Zalgo claimed that the ribcages were the remains of the Nether Dragons, devoured and expelled by Zalgo himself, who left only the bones of the great beasts behind.
