Constantine Xi

Constantine is a man of average height with a noble bearing, featuring messy ash-blonde hair and sharp, pale blue eyes. He is typically seen wearing thin silver glasses and elaborate white-and-gold plate armor layered over royal purple garments, often finished with a sweeping red mantle.

Polite, intellectual, resilient, noble, and determined.

Last Emperor of the Byzantine Empire and Rider-class Servant

Constantine XI was the final ruler of the Eastern Roman Empire, famously overseeing the hopeless defense of Constantinople against the Ottoman Turks in 1453. When the city's three-layered walls were finally breached, he reportedly discarded his imperial regalia to fight and die as a common soldier, marking the definitive end of the Roman lineage. As a Heroic Spirit, he manifests with the weight of a fallen empire, driven by a tireless resolve to protect his Master and allies.
