Driven by an all-consuming hatred of living things, these spectral horrors sweep across the realms in great hosts, killing everything in their path. They remember only dim echoes of their past, fragments of the person they were, and half-faded memories of the events that led to their current predicament. This is enough to keep them in a state of perpetual torment, which pleases cruel Nagash. On occasion the Great Necromancer will assemble smaller groups of Nighthaunts in order to achieve a particularly delicate task. Their incorporeal nature and resistance to most physical damage makes the gheists particularly suited to such missions.
