He has fought in countless battles, both on and off the War Altar of Sigmar - a mobile shrine of divine power.
Sigmar was a warrior in life and a god to fighters upon his ascension, so his clergy follow their Lord's example - none more so than Volkmar the Grim. He is no cleric hiding away from what he decries, nor a priest more content with the wealth and status such a position brings - an accusation that has been justifiably levied at Grand Theogonists in the past. He is a pious and foreboding man dedicated to the destruction of evil, whether it takes the form of Chaos or the rotting darkness of Unlife. Volkmar the Grim is both leader and spiritual head of the Cult of Sigmar. He stands at the forefront of the battles against those that would see his beloved realm torn asunder, and it is a responsibility that weighs heavily upon his shoulders. There is little doubt that Karl Franz is one of the greatest generals of his age. The Emperor frequently takes personal command of his soldiers, like Sigmar, the Warrior-God of old, smiting enemies of the Empire with every blow. He is also a military genius and a valiant general. Karl Franz is said to be the greatest statesman the Old World has ever seen.
The Emperor is Karl Franz, Prince of Altdorf and Elector Count of Reikland.
