Cult of Sigmar

The Cult of Sigmar, sometimes known as the Church of Sigmar, or simply as the Sigmarite Cult, is a state-official religious organization that has dedicates their existence to the worship and prayers of the Empire's patron god; Sigmar Heldenhammer. The Cult of Sigmar was founded by a wild eyed Friar named Johann Helstrum in the Imperial year of 73 IC, where he appeared before the masses to relate a vision that he had experienced of Sigmar kneeling before Ulric, who then placed the crown of godhood upon his brow and took his place amongst Pantheons. Ever since then, the Cult of Sigmar has grown until it arguably became the most powerful religious force within the domains of the Empire, so strong that Sigmar has supplemented Lord Ulric as the Empire's new patron God of War.
