Spoilers: The Tower command and his battlefield kit; no campaign ending.

Servant of Ghorth, commander of the Tower
The 28 March 2023 introduction makes Zhatan commander of the Tower of Zharr and servant of Ghorth the Cruel. The work is labour and sacrifice: captives and resources for the industrial empire. The line the piece uses is that the fiercest fires forge the hardest steel. Ghorth is the master in that sentence. He is not a Legendary Lord on the faction select.
Forge of the Chaos Dwarfs is the pack, with Update 3.0 on 13 April 2023, shared with Astragoth and Drazhoath. Astragoth sits at the head of Hashut's cult and draws Conclave Influence. Drazhoath wants Zharr-Naggrund back from the Black Fortress. Zhatan's campaign uses the same Labour economy, Hell-Forge, convoys, and Tower seats, pointed at supply rather than at the High Priest's politics.
The melee lord and the named kit
Zhatan fights in person. The introduction puts him on foot, on a Lammasu, or on a Great Taurus. The Sadistic Snare is his net. Boundless Cruelty is the aura. The named equipment is the Obsidian Axe, the Armour of Gazrakh, and the Chaos Rune Shield.
Infernal Guard are the line that lets a melee lord stay in a useful fight. K'daai Fireborn are the assault that follows. Gorduz Backstabber, the pack's Hobgoblin hero, supports a Hobgoblin contingent inside a Chaos Dwarf army, Zhatan's included. A Tower seat bought with Conclave Influence is a political action shared with the other two lords. The captives that feed Labour are the part of the war the introduction gives to Zhatan specifically.
The Drill, the sandbox, and Ghorth
In the Realm of Chaos the race builds the Great Drill of Hashut. That objective is the pack's story campaign. Immortal Empires does not hand Zhatan a finished conquest of the Tower, and it does not make Ghorth a selectable lord. Ghorth remains the name on the introduction.
What the player manages is the supply chain and the fight. Mines, factories, and Control decide whether the captives become arms. The axe and the shield decide whether the commander lives through the battle those arms were built for. Astragoth's petrified frame and Drazhoath's taurus are other answers to the same roster.
