Konstantinos XI

The last emperor of the Byzantine Empire, also known as the Eastern Roman Empire. Rome, in all its greatness, is said to have finally died with him, after the fall of Constantinople. Even as the empire was on the verge of ruin, he fought to protect it.

While he usually strives to always be polite and friendly, he sometimes speaks and behaves more roughly in times of duress.

A mild-mannered intellectual who projects an air of nobility. Though he seems willing to accept defeat, he is determined to fight as best he can all the same...even if that determination is not readily apparent to anyone else. This, most likely, is owed to the sort of hero he is: the emperor who died with his empire.

For him, the seeming paradox that loss and ruin are inevitable and yet he must still fight them with all the strength he can muster is as natural as breathing.

Hagia Sophia's Prayer: C-

Gives the user the protection of the Hagia Sophia. Unfortunately, this effect doesn't amount to all that much in modern times.

Empire's Decline: EX

Since Kōnstantînos XI was the last emperor of the Byzantine Empire, one could say that ancient Rome's influence died completely on the day Constantinople fell to Mehmed II.

Demise Privilege: C

A variant of Imperial Privilege. Through concentrated effort, it is possible for individuals to acquire certain skills they normally wouldn't possess, though only for a short period of time. Kōnstantînos, being the final emperor of Rome, lacks many of his predecessors' more far-reaching privileges, and on top of that, it takes much more magical energy for him to wield what privileges he does have. But even though he vanished into the battlefield as just another soldier, in the end, he was still able to pass these privileges on to others.

Oath of the Three-Layer Wall.

A pseudo-descent Noble Phantasm which mimics the three-layer wall that made Constantinople impervious to attack. It promises protection for up to 7000 people. Any more than that and it becomes increasingly likely to fail. In fact, Kōnstantînos believes that in practice, it can only actually keep around 1000 people perfectly safe. Now that he has been summoned to Chaldea, he has made it into an even more potent defense to ensure Master and those who stand alongside them remain safe.

Thanks to Kōnstantînos being the last emperor of the Byzantine Empire, this Noble Phantasm can also influence Europeans from the two-hundred year period surrounding his life, whether they are friendly or not. However, this influence varies depending on the person's faith, and has essentially no effect on a strong believer in a different religion.

Kōnstantînos XI was the last emperor of the Byzantine Empire (also known as the Eastern Roman Empire, as he claimed he and his people were descendants of the Roman Empire).

The Byzantine Empire was once a flourishing trade hub, but fell into decline in consequence of religious conflicts between the East and West, as well as relentless attacks from the Ottoman Empire. By the time Kōnstantînos XI ascended to the throne, the empire's territory had already been reduced to Constantinople and the area immediately surrounding the city; no power in such a precarious position could truly be called an empire.

A distant descendant of Michael VIII Palaiologos, the founder of the Palaiologos dynasty (specifically, Michael's grandchild's grandchild's grandchild) Kōnstantînos XI and his family were powerless even to stop their palace from crumbling. Consequently, they were forced to live in a small, only barely habitable section. Some time after Kōnstantînos XI took the throne, the young sultan Mehmed II decided to take Constantinople for himself. However, Kōnstantînos XI rejected Mehmed's envoys when they demanded his surrender, sparking the beginning of Mehmed's desperate siege.

Kōnstantînos XI tried seeking aid and reinforcement from neighboring countries, but with hardly any both able and willing to send troops, he had to face the siege with only a few soldiers and mercenaries. He and his 7000 soldiers held the line against Mehmed's army of a hundred thousand for around two months thanks to his three-layer bulwarks, but in the end, Constantinople ultimately fell.

Perhaps because Kōnstantînos XI waded into the battle himself with his trusty sword, his body's whereabouts remain unknown to this day.

In Traum

Kōnstantînos fought in the war between realms not in defense of humanity, but in revolt against it. He did so for the sole purpose of reinstating Pope Johanna—a being who belonged to Proper Human History even as it relegated her to fiction.

To say she wasn't angry about being forsaken would be a lie, but that alone wouldn't have been enough to spur him to attempt to unite the realms.

No, what drove this emperor here was neither anger, nor hatred, nor love for the nation he once gave his life to defend, but a desire to do whatever he could for this woman who understood she was no more than a fantasy and still stood up for the world who condemned her to that fate.

In his final moments, as he thought back on all that had happened, he did so not as a farewell gesture, but simply to cherish the memories he had cultivated with all his allies and friends.
