The Tower of Zharr is a campaign mechanic for 
Chaos Dwarfs that allows them to spend 
Conclave Influence to obtain various factionwide benefits and eventually confederate other Chaos Dwarf factions.
Overview[]
The Tower of Zharr has multiple seats which playable Chaos Dwarf factions can spend Conclave Influence to obtain. Each seat provides benefits to the faction that claims it. After a seat has been claimed, another faction can usurp the seat to obtain the benefits for themselves, but doing so costs more Conclave Influence than first claiming it and inflicts a temporary penalty to diplomatic relations with the faction whose seat was stolen. Each time the seat is usurped, the cost goes up further. When a seat is claimed or usurped, it cannot be usurped again for three turns.
Seats are organized into four tiers, and the first three tiers are organized into three districts: Sorcery, Military, and Industrial. When all seats in a district are claimed, the district is completed and a set of benefits are unlocked for all Chaos Dwarf factions. When two districts in a tier are completed, the next tier of seats is unlocked.
The fourth tier has just three seats, allowing the faction that claims them to confederate the Servants of the Conclave or one of the other two playable Chaos Dwarf factions. Confederating one of the other playable factions gives you control of all of their seats in the Tower of Zharr. Tier four seats cannot be usurped.

Strategy[]
In the early game, seats that improve Raw Material or Armament output are the most valuable. The AI also values them highly, so you should move on them quickly before they are claimed. Seats that give ancillaries are useful but not essential, and Chaos Dwarfs do not get many ancillaries through other means. Seats that increase unit caps are more valuable late in the campaign when the Armament cost of increasing those caps has gone up significantly. Seats that provide army abilities are very valuable because they can improve the effectiveness of all of your armies factionwide.
District bonuses are permanent and apply to all Chaos Dwarf factions, so you are incentivized to complete districts even if the individual seat benefits are unimpressive.
Once you reach tier four, you can choose to confederate another Chaos Dwarf faction. Confederating the Servants of the Conclave first is usually a good choice because this will give you access to a fully developed province including a tier 5 Tower and multiple special buildings, as well as two full armies. On the other hand, the Servants of the Conclave don't try to expand their territory and the 2 massive high-tier armies upkeep may impede your economy, so the other factions can give you more settlements, a powerful Legendary Lord, and all of the faction's seats in the Tower of Zharr. Eventually you will want to take all three seats, giving you full control of the Chaos Dwarf empire.
