While ostensibly part of the Imperial Troll Military Forces, the Royal Palace Guard hold a largely ceremonial role as the guards of the Imperial Palace and Imperial Hall of Records, though also serve to prevent people from entering the buildings without permission. They are noted for their distinctively ornate purple and gold armour and the halberds they use, though they are both more for show than practical use. Despite this, the Royal Palace Guard are still an extremely effective fighting force, being formed as it is of experienced, highly decorated former servicemen.
During the events of A Short Month, the Imperial Guard was able to blunt the attack on the palace by the Dragon Army and allow the Immortal Governor to launch a counter attack.
