Unholy runes carved into the corpse of this once majestic horned behemoth empowers it with fell energies, every step of the mammoth’s wounded limbs shaking the ground around it. Even before the reawakening of their infernal dwarven masters these accursed creatures were forced into an unlife of servitude, strange and wicked machinery of ancient make working in tandem with blasphemous magics to animate them inexorably forward.
