At the dark heart of the Realm of Death rises Nagashizzar, the Silent City, throne-fastness of Nagash the Great Necromancer, God of the Dead. It is a place of towering black bone and endless obsidian galleries, raised and razed and raised again across the turning of Ages, always to the singular will of the Undying King. No living thing draws breath within its walls; the only sound is the whisper of dust and the grinding of vast necromantic engines.
Here the harvested souls of the realms are dragged to be judged, unmade, and reforged. In the bone-tithe manufactories, the Ossiarch Bonereapers are constructed, their legions distilled from the crushed skeletons of a hundred cultures, each warrior an amalgam of the dead denied even the dignity of their own bones. It is industry on a cosmic scale, the mass-production of eternity's soldiery, tended by mortarchs and liege-kavaloi in silent, tireless devotion.
To look upon Nagashizzar is to understand the true horror of Death's dominion. This is no restful tomb but a factory of the grave, where the promise of the afterlife is revealed as mere raw material for a god's endless armies. All who die owe Nagash a tithe of bone, and from that grim harvest the Silent City labours on, patient and pitiless, building the strength to one day claim every soul in creation as its rightful and eternal property.
