Location from The Locked Tomb by Tamsyn Muir
Trentham — the military heart of the Nine Houses, producing soldiers, officers, and the Cohort's rigid chain of command.
The Second House produces the Cohort's officers and military leadership. Its culture is disciplined, hierarchical, and devoted to the Emperor's imperial mission. Necromancers from the Second specialize in energy transferral for combat applications. Their cavaliers are Cohort-trained soldiers first and courtly swordsmen second. Pyrrha Dve originally commanded its special intelligence division before the Lyctoral process. Ten thousand years later, the Second House still runs on the institutional culture she helped build.
A planet organized around military infrastructure — training grounds, barracks, command centers, and the kind of institutional architecture that values function and authority over comfort. Everything is orderly. Everything has a chain of command.
