House Orlock is one of the six families who make their home in the “Hive City” part of Hive Primus, the capital of Necromunda. The Orlocks, as house members are commonly known, are responsible for the production of the majority of the iron in Hive Primus, which has led to the house earning the sobriquet of “House of Iron”.
The Orlocks have a longstanding rivalry with the mysterious House Delaque, due to the Orlocks sabotaging a Delaque factory, which led to the Delaques losing a very lucrative business contract with the noble house Ulanti. When the Orlocks got the contract instead, things only escalated, and the Delaques retaliated by assassinating Lord Hagan Orlock. The chances of either house burying the hatchet is infinitesimally small.
As for the other houses, the Orlocks are on surprisingly good terms with the matriarchal House Escher, due to the Orlocks traditionally treating the women very well, especially compared to the other houses.
