Grave Guard are elite units in the Warhammer fantasy universe, specifically associated with the Undead faction. They serve as protectors of tombs and ancient burial sites, often appearing as skeletal warriors clad in heavy armor. Their primary role is to defend their masters and maintain the sanctity of the graves they guard. These warriors are typically armed with a variety of weapons, including swords and halberds, and are known for their resilience in battle. Grave Guard are often accompanied by powerful leaders, such as Lords or Necromancers, who command them to rise from the dead and fight for their cause.
