The Ossiarch Legions are the bone-constructed armies of Nagash, forged not from the crude reanimation of corpses but from the harvested bones of the fallen, remade into flawless soldiers by the artistry of the Mortisan crafters. Each warrior is an assemblage of many dead, its skeletal frame reinforced and reshaped into a perfect instrument of the Great Necromancer's will.
The ossiarch-bonereapers levy a grim tithe of bone from every kingdom of the living, sending forth their legions to collect the dues owed to Death. Those who refuse are simply harvested where they stand, their skeletons marching away to be reforged into the next generation of Nagash's tireless host.
Cold, methodical, and utterly without mercy, the Ossiarch Legions embody Nagash's vision of a universe reordered under the dominion of undeath. They do not tire, they do not fear, and they do not stop until the bone-tithe is paid in full.
