The Imperial Cult
The Imperial cult is not a proper religion in the sense that most of its followers do not attribute divine properties to the Emperors, The Empire of the White Flame as an institution, or any of its heroes, still they worship them finding examples to follow and ways of living their life the way they think is best.
The cult has no unified pantheon but almost all members would agree that Gustavus Adolphus, the first emperor is the most revered figure in the cult, though others such as Princess Aurelia or Ollaneus Piers are also highly regarded, the cult is highly militarized believing that is the duty of every good citizen to serve the Empire in war, the cult does not hate or see other races as inferior but it believes that the only worthy culture is the imperial one, believing that invading a lesser culture will bring prosperity and riches to the poor savages, integrated people from other races such as goliaths are lauded as to have made the best choice and Leonins are worshipped both for their Lion like appearance and their warrior culture.
