Card Trivia:Heraldic Beast Twin-Headed Eagle
- This card is based on the Double-headed eagle, which is a common symbol in heraldry and vexillology. It is most commonly associated with the Byzantine Empire, the Holy Roman Empire and Russia. In Byzantine heraldry, the heads represent the dual sovereignty of the Emperor (secular and religious) and/or dominance of the Byzantine Emperors over both East and West. In the Holy Roman Empire's heraldry, it represented the Church and the State. Several Eastern European nations adopted it from the Byzantines and continue to use it as their national symbol to this day, with the most prominent being Albania, Serbia, and Russia.
