Theodosius Constantinos

is the Noble Phantasm of Constantine XI. 
When Mehmed II sieged with 100,000 men, Constantine XI and his 7,000 soldiers were able to defend the city for two months thanks to these walls.
This Noble Phantasm is the pseudo-advent of the threefold walls which marked Constantinople as impregnable. Although this Noble Phantasm promises to safeguard a vast range, encapturing a maximum of 7000 people, as the number of people increases, the likelihood that it will fall rises, diluting the bestowed protection. Constantine himself considers 1000 people to be the limit if the aim is to actually provide stable defenses.
When summoned by Chaldea, he constructs an even more robust fortification, utilizing his Noble Phantasm on the Master and party alone. Because he was the last emperor of his empire, he can exert his influence over friend and foe alike, albeit limited to Europeans who lived within approximately 200 years of his own life. However, the effect rises and lowers according to the profundity of faith, and it would effectively not apply to someone of a different sect.Fate/Grand Order - Constantine XI profile, Translated by Savepoints
==Development==
Initially, the Noble Phantasm animation incorrectly depicted the with minarets, which were not there during Constantine's life as they were added after the Ottomans conquered the city. This was fixed in an update several days after Constantine was implemented.
