The assassination of Julius Caesar was the result of a conspiracy by many Roman senators. Led by Gaius Cassius Longinus and Marcus Junius Brutus, they stabbed Julius Caesar to death in a location adjacent to the Theatre of Pompey on the Ides of March (March 15), 44 BCE.

Caesar was dictator of the Roman Republic at the time, having recently been declared dictator perpetuo by the Senate. This declaration made several senators fear that Caesar wanted to overthrow the Senate in favor of tyranny, yet the conspirators never restored the Roman Republic. The ramifications of the assassination led to the Liberators' civil war and, ultimately, to the Principate period of the Roman Empire.

Internal Warehouse Events

Those are the facts that modern history has accepted as truth, which is where the deviation with Warehouse events occurs. What actually occurred was that Caesar was heavily involved in Warehouse matters and security, as he unsuccessfully tried to capture the artifacts of Warehouse 2. Worried about his ambition to control the world through the Warehouse, the Regents sanctioned his assassination attempt, paying off twenty-three conspirators to murder him, including Marcus Brutus as their leader.


When one of the daggers is held, the other 22 daggers will protect the user. When the user points the dagger at a target, each of the other daggers will stab the target. The user will then begin to bleed internally, as if they were the target.


The daggers were all separated after the assassination of Caesar. The first two daggers were collected by the Warehouse in 410 AD in Rome after reports of a thief who was protected by a flying dagger reached the Warehouse. Realizing these were the same daggers given to the conspirators by the Regents, the Warehouse managed to collect them, only to realize that they were unable to be neutralized.

The biggest detriment for the Warehouse was that the daggers appeared to have an active range that would bring the other daggers to whichever one had currently activated, making tracking the artifacts much more difficult. The next Blades weren't collected until 762 by Agents, who managed to collect two more. Three more were collected in 912. Over the next thousand years, ten more have been collected across various Warehouses, usually in pairs of at least two (Excluding the single blade collected in 1375). No additional Blades have been collected since 1912, leaving six blades left uncollected.
