The Emperor Sigismund was given this huge enchanted horn by the Dwarfs after the battle of Grimgrill Dale. After the death of Sigismund during the siege of Altdorf the horn passed into the keeping of the Temple of Sigmar. It has remained in the temple ever since, and is blown three times on the anniversary of the death of Sigismund as a solemn reminder of the dark days when the Empire was ravaged by Orcs and Altdorf was almost destroyed. It is said that when the horn is blown, the enemies of the Empire hear the angry roar of Sigismund himself and they flee before the wrath of the vengeful dead.
