|“||But it seems these men have been plotting against us for very long time. They funded Luke Castellan's war. They supplied aid to Camp Jupiter when the Romans attacked Camp Half-Blood. And despite those two wars, the Triumvirate is still out there-still plotting. What if this company is the root cause of...well, everything?||”|
Triumvirate Holdings is an organization with three powerful individuals who are said to be the three worst Roman emperors. They have forced others to worship them, which helped them gain their divinity. Currently, there are two identified members, Nero, historically considered to be one of the worst emperor of all and, and Commodus, who currently resides in Indianapolis. Triumvirate Holdings profits off events such as the Second Titan War. They are said to "own so much property and have so much money they make Rachel's dad's company look like a kid's lemonade stand."
The company is said to have existed in the shadows for centuries. During the Second Titan War, Triumvirate Holdings supplied Luke Castellan and his allies with the Princess Andromeda, weapons, helicopters and top human mercenaries. Then during the Second Giant War, they supplied Octavian, the former augur of Camp Jupiter, with weapons such as onagers.
