马库斯·尤尼乌斯·布鲁图斯（拉丁语：Marcus Junius Brutus Caepio，前85年－前42年10月23日）是晚期罗马共和国的一名元老院议员，同时也是一位刺客组织的成员。
公元前45年之前某时，布鲁图斯成为罗马元老院的一员。公元前47年，他和同僚盖乌斯·卡西乌斯·隆基努斯是两个最早的刺客兄弟会的雏形无形者的最初成员之一，后来艾雅所招募。Both of them later met up with Aya in Alexandria, where they made preparations to head to Rome and combat the Order of the Ancients there. When Aya's fleet was attacked by Roman ships, Brutus and Cassius helped to assist her before making their journey to Rome.
Around 45 BC, many senators began to fear Caesar's growing power following his appointment as dictator. Aware of Caesar's connection to the Order of the Ancients, the Hidden Ones began leading a conspiracy against Caesar, recruiting forty senators and called themselves the Liberatores.
- “Dreams of the cavern again! I run my phantom hands along its walls and recognize every flaw. There is writing here, but I cannot read it.”
- ——Brutus speaks of his dreams.[来源]
For some time, Brutus' dreams were haunted by a mysterious cavern that he found himself compelled to find. Eventually, he was led to discover the sealed First Civilization vault hidden beneath what would eventually become the Santa Maria Aracoeli.
As he had been assigned by Gaius Cassius Longinus as the one to come up with the plan of assassinating Caesar, Brutus designated the temple preceding the vault as a meeting place for his co-conspirators.
Whenever his fellow Assassins left after their council meetings, Brutus would explore the cavern on his own, coming across what had supposedly drawn him to the location, "Whispers. Lights flickering through cracks in the earth. A doorway that is also a puzzle."
Eventually discovering how to gain entrance to the vault, Brutus was struck to awe by "phantom radiance" of the otherworldly architecture, and found the "very pillars of [his] beliefs toppled." Upon approaching and activating the vault's pedestal, Brutus was shown Rome in flames; the aftermath of Caesar's assassination, which ultimately drove him into action.
Brutus would later write several scrolls describing his dreams and discovery of the vault, as well as include drawings of the chamber and its pedestal. Following the assassination of Caesar, Brutus also returned to the temple to store these scrolls, as well as his heirloom armor.
- “I relay my plan; some details are my own, but others driven by my visions. My contributions are practical: we will attack as a group to prevent escape and to ensure each of us is committed to this task. We will lure him to the Senate, where none of his allies may enter.”
- ——Brutus planning Caesar's assassination.[来源]
Inspired and encouraged by the visions he had seen in the vault, Brutus devised the plan for the assassination alongside thirty-nine other senators. As dictated to him by his visions, Brutus scheduled their attack for the Ides of March.
That day, however, Caesar's wife attempted to convince him not to attend the Senate, delaying his arrival and leading the Assassins to fear that the plot had been found out. Brutus persisted nevertheless, waiting for Caesar at the Senate, and upon his eventual arrival, they attacked him with the help of Aya.
The rest of senators then followed, stabbing Caesar twenty-three times. Caesar resisted at first, but resigned himself to his fate upon recognizing Brutus, who delivered the last stab to Caesar, killing him. With Caesar dead, Brutus declared that Romans were now free from the tyrant. After the assassination, Brutus was driven to severe guilt from his actions and later returned to the Colosseum, abandoning the dagger he had used to strike down Caesar within the vault, along with the armor and scrolls.
- “Whatever power lies within this artifact, it has not returned our Brother to us. We close his eyes again. There is no sign that he had ever moved.”
- ——The attempted resurrection of Brutus.[来源]
After the assassination, the Senate passed an amnesty on the Assassins, which was proposed by Caesar's friend and co-consul Marcus Antonius. Nonetheless, uproar among the population caused Brutus and the other Assassins to leave Rome. Brutus settled in Crete from 44 to 42 BC.
Eventually, armies under the command of Caesar's allies clashed with those of Brutus and Cassius at the Battle of Philippi in Macedonia. Faced with certain defeat, the two Assassins fled and committed suicide.
After Brutus' death, his followers gathered in Philippi, Macedonia, and tried to use the Shroud of Eden to bring him back. However, the Shroud was not capable of such restoration, and though Brutus opened his eyes and moved, he did not appear to breathe, and eventually fell still in a seeming second death.
Some time prior to 1500, the Followers of Romulus discovered the temple, and found Brutus' armor and dagger within. They took the artifacts, hiding them in a chamber in the tunnels beneath Colle Palatino. The chamber was to only be opened with six keys, spread across various landmarks throughout Rome, hidden alongside the scroll Brutus had written.
- In 1503, Giovanni Borgia relived some of Brutus' memories, due to them both having been exposed to the Shroud of Eden.
- Brutus' ability to activate the vault pedestal suggests that he is a descendant of the First Civilization.
- The poet Dante Alighieri wrote in Inferno, the first part of The Divine Comedy, that Brutus, along with Cassius, were condemned to the lowest circle of hell because of their act against Julius Caesar, despite the fact that Dante was a member of the Assassin Order.
