A Solo Servant summoned by the Moon Cell to act as SE.RA.PH's systems admin.
He is given form as a technician to perform maintenance on SE.RA.PH, but after coming into contact with the harvester of worlds known as the Umbral Star, Archimedes becomes its devoted apostle.
When he interfaces with the once-sealed Ark of the Stars, he becomes corrupted by its influence. He then begins to make preparations so that the Umbral Star can consume the Moon Cell once and for all.
Although he acts like a vassal of the Umbral Star, he has no intention of placing himself beneath it. For its part, the Umbral Star has no method to control Archimedes either.
If asked why he would work for the Umbral Star, Archimedes would reply with:
"No reason. I are simply bored of the civilizations of Earth. I want to know about how the intelligence of other sentient life forms is constructed."
In this story, he is the mastermind who awakens Altera's deadliest form, the White Titan Sephyr.
Archimedes is introverted, stubborn, and active.
He is the personification of order, individualism, reason, and rationality.
He is loquacious, but while his tone is gentle, there is a fire behind his words.
He is a curious creature, both social and rational.
Archimedes believes that the world should be peaceful, and does his best to ensure that it is, but he also places himself above this level of reasoning.
"Totalitarianism is the best method to achieve societal happiness. This is because we are able to acquire more resources in the most efficient manner by these means. This is how a system should be. Yes, indeed... All human beings, aside from myself, should work for the greater good."
He approves of a society that is logical, but not necessarily because he dislikes conflict; rather, he thinks that it is necessary to sustain a machine with high productivity.
Archimedes believes that the solutions he seeks are paramount to everything else, and he has used everything and anything as mechanisms to help him achieve his goals.
The foolishness of humans... The weakness that prevents them from accepting reality for what it is because they prioritize their emotions... This is what he hates, but it is not a personal dislike so much as animosity towards the overall way humans exist.
Archimedes hates the way humans cannot succeed individually without creating a "hideous" society, and is disappointed in people whose opinions are swayed by their emotions. Thus, it is rare for him to show his animosity in front of people.
Originally, he lived around c. 287 BC — c. 212 BC as a mathematician, engineer, and astronomer.
He was born to a line of artists, and took up astronomy just as his father did before him.
At the point of his death in the year c. 212 BC, he resided in the city of Syracuse, located on the eastern coast of current-day Sicily.
Archimedes' famous achievements involve a range of geometrical theorems from "On the Equilibrium of Planes," "On the Measurement of a Circle," and "On the Sphere and the Cylinder," as well as "Archimedes' cattle problem" in Diophantine analysis.
While his peers respected him as a genius, they also considered him rather strange.
He lived in proud seclusion far from Alexandria, the hotbed of academic pursuits at the time, and preferred written correspondence to face-to-face dialogue.
Most scholars of his era treasured recognition just as much as discovery, and basked in the praise of the citizens around them.
Archimedes had no such interest, and was said to have been fixated on the beauty and accuracy of his own theorems.
Archimedes was also the cornerstone of Syracuse's defenses, as he was even more talented as an engineer than he was as a mathematician.
The seaside city-state relied on his supreme war machines far more than it did on ordinary soldiers.
Plutarch wrote in his Parallel Lives that Archimedes was related to King Hiero II, the ruler of Syracuse. It is easy to imagine how he ended up in the position of chief engineer tasked with the defense of the city-state.
Archimedes' fame as an engineer was known throughout the land from early on. Ancient Greek historian Polybius, born in c. 200 BC, wrote the following account in his Universal History some seventy years after Archimedes' death:
"If you were to see these works, you would easily understand how the intelligence of a single human being can bring about amazing achievements if they are given the proper stage. In truth, the Roman armies who had shown overwhelming might on the planes of both ground and sea were convinced that they would be able to conquer the city-state of Syracuse should just that single old man disappear. However, as long as Archimedes existed, and his methods of protecting Syracuse were in place, they would fear to tread anywhere near the city's walls."
Many of the defense mechanisms he invented effectively demolished a variety of would-be invaders.
However, in the year of c. 212 BC...
Syracuse formed an alliance with Carthage during Carthage's Second Punic War against the Romans, and so Syracuse and Rome became enemies.
Consequently, a Roman force led by the General Marcus Claudius Marcellus laid siege to the port city by both land and sea.
Archimedes' fortifications effectively repelled the invaders, but the city fell due to treachery, and Archimedes lost his life in the aftermath.
However, his story comes to an end after the siege, rather than during it.
Archimedes' name was well known to the Romans, and the victorious General Marcellus sent out orders that the scholar was not to be harmed. According to the popular account given by Plutarch in his heroic tale Parallel Lives. Archimedes was contemplating a mathematical diagram when the city was captured. A Roman soldier commanded him to come along, but he declined, saying that he had to finish working on the problem. The soldier then flew into a rage and killed Archimedes with his sword.
(Plutarch calls this story a mere rumor, and clarifies that there were other rumors as well, like one stating that Archimedes was killed because the soldier thought the technical drawings in his possession would be valuable spoils of war.)
It is said that Archimedes' last words, uttered to the soldier who stopped him while he was drawing geometric configurations in the sand, were "μὴ μου τοὺς κύκλους τάραττε," meaning "Do not step on my figures/ Do not disturb my circles!"
Despite those last words being well known, they are not noted in Parallel Lives, and their source remains a mystery.
One final bit of trivia: When the Roman orator and politician Marcus Tullius Cicero was serving as quaestor in Sicily in c. 75 BC, he reported finding the tomb of Archimedes near the Agrigentine gate in Syracuse, clearly neglected and overgrown with bushes. It is said that the tomb contained a sculpture illustrating the late scholar's favorite proof, consisting of a sphere and a cylinder of the same height and diameter. This was one of the greatest mathematical accomplishments of his life.
In the world of Fate, Archimedes lived his mortal life as a man who could not see the beauty in anything other than the solutions he created within himself. Because of his great intellect and his broad view, however, he was never ostracized from society.
Even though he was resigned to the fact that he was "different" from everyone around him, he was also socially adept and magnanimous, and his genius contributed greatly to the advancement of Syracuse.
Other mathematicians of the time only pursued the "beauty of their theorems," and did not concern themselves with the way society should be.
And so Archimedes could even be considered an aberration of his time, as he performed work in both math and industry.
His dual nature is what led to his conflicted personality as both an engineer, in the service of mankind, and an egoist.
After he becomes corrupted by the Umbral Star, his frustrations with both his own failings and the foolish commoners all rise to the surface, turning him aggressive.
Truth be told, he is in a constant state of anger.
He recalls every goal he failed to achieve in life...
He laments that humanity makes the same mistakes over and over...
His superior intelligence is still his defining trait.
Which makes him angry about everything.
And so, he thinks nothing of manipulating others.
As a matter of fact, he enjoys it. He had always thought that the only things that would move as he intended were his numbers, his creations. But after all this time, he has realized that even the world itself is merely a tool, one he can manipulate to his heart's desire.
So he hides his aggressive nature with a smile, and finds joy in the way he can now draw fully upon all of his strengths to achieve his goals.
"Previously, I had only found joy in numbers."
"Troublingly enough, I now find that my own life is somewhat amusing."
One could even say that Archimedes has finally regained the innocence of his youth.
He can even smile at his enemies, as he considers everything a "tool."
He recognizes the obstacles before him, but he does not hate them. Even if he is betrayed, as long as the process that led to his betrayal is logically correct, he is satisfied with the outcome.
What he truly dislikes and finds distasteful are opponents who have "strayed from logic."
He loathes those who would not choose the correct answer when it's right in front of them.
His mortal enemies are those who would rampage down the wrong path at full speed without a shred of reasoning.
