The political faction that Sigmar Heldenhammer is the patron deity of is based on what real-world empire?
Sigmar Sigmar Heldenhammer is a fictional deity in the "Warhammer Fantasy" setting. He is the patron deity of The Empire. Before he became a god, Sigmar was a man, albeit an exceptional, perhaps even superhuman one. The young chieftain of the Unberogens who lived 2,500 years before the present day of the Warhammer universe, he united the barbarian human tribes into what would become the mightiest human nation – the Empire. His sign is a twin-tailed comet or a war hammer.
Greater Iran Greater Iran (Persian: ایران بزرگ‎ ‎ , "Irān-e Bozorg"), also referred to as Greater Persia (سرزمین پارس , "Sarzamin-e Pārs"), is a term used to refer to the regions of the Caucasus, West Asia, Central Asia, and parts of South Asia that has significant Iranian cultural influence due to having been either long historically ruled by the various Iranian (Persian) empires (such as those of the Medes, Achaemenids, Parthians, Sassanians, Samanids, Safavids, and Afsharids and the Qajar Empire), having considerable aspects of Persian culture due to extensive contact with the various Empires based in Persia (e.g., those regions and peoples in the North Caucasus that were not under direct Iranian rule), or are simply nowadays still inhabited by a significant amount of Iranic peoples who patronize their respective cultures (as it goes for the western parts of South Asia, Bahrain and China). It roughly corresponds to the territory on the Iranian plateau and its bordering plains. The Encyclopædia Iranica uses the term "Iranian Cultural Continent" for this region.
