Zoroastrianism

Zoroastrianism is a key religion in Europe. Although not widely practiced by many people, a large minority of nobles in the Holy Roman Empire have elected to follow or otherwise convert to Zoroastrianism, most notably the House of Mullenstone, a cadet branch of the house of Hapsburg, and the ruling family in the Holy Roman Empire. Other converts include key members of House Mandorf of Hanover, House Steiner of Bern, and House Valois of Paris.
