The Vespers were an extremely dangerous organization and were enemies of the Cahills.



The Hunt was always leading to this.

The Vespers were a family, dating back to the early 1500s, just like the Cahills. According to the Black Book of Buried Secrets, they evolved into an organization, and, according to George S. Patton, they recruit the best in the world and aren't picky apart from that the recruits need to have talent. Damien Vesper, the first Vesper, was Gideon Cahill's best friend until he betrayed him for the Master Serum, forcing Gideon to start the fire which burned down Gideon's laboratory, as seen on the back of the Thomas Jefferson Cards Card Combo. It is known that they are the Cahills' worst enemy. The Vespers have been sabotaging the Cahills from the start and framed Buchanan Holt for giving the Ekats the secret message. In the introduction to the The Black Book of Buried Secrets, Rick Riordan stated that every author agent (i.e. Margaret Peterson Haddix, Jude Watson, Patrick Carman, etc.) present during their meeting seemed to be terrified by the mere mention of the Vespers. They seem to be worse than any Cahill. As stated by William McIntyre, "They make Isabel Kabra look like Mother Teresa," and that from the reader's standpoint, Isabel is generally considered the worst, cruelest, and most ruthless Cahill. Isabel Kabra's parents had ties with the Vespers, as her maiden name was Vesper-Hollingsworth. Her mother’s last name was Vesper. Arthur Trent, Dan and Amy's father, was part of a family that had ties to the Vespers, but after marrying Hope, disowned himself from the family. Broderick Wizard, Jonah's father is most likely a Vesper, as Grace herself suspected him of being a Vesper. The Vespers attacked Amy, Dan and Fiske Cahill in Switzerland at a bank while the trio were dealing with Grace's account while retrieving Gideon's Ring. Amy and Dan were close to getting captured but were rescued by two skiers, Erasmus, and Fiske. In the Black Book of Buried Secrets, Amy calls Jonah Wizard, and, in a panicked voice (over much static), says, "They found us. The Vespers are coming." It is suspected that the Vespers are after Gideon's Ring. At the end of the Cahills vs Vespers series, it's revealed that Gideon's Ring along with many of the items the Vespers forced the Cahills to find were all components to a Doomsday device the organization planned to use to control the world. During the final confrontation, Vesper One attempted to start the device but was killed by Isabel Kabra (Vesper Two) who took the Cahill serum in revenge for the death of her daughter. The Vesper Council of Six was rendered defunct as Vespers One, Two and Five were killed, Vesper Three having defected, and Vesper Four and Six in custody. Later Amy Cahill contacted other members of the Cahill family and other agents into destroying the remain Vesper bases to make sure the Vespers never rise again.

Many people think the Lucian branch and the Vespers are exactly alike, but there is a difference. The Vespers are full of ruthless people who would do anything to succeed and are not a family, while the Lucian branch are full of determined leaders and spies that are family. One of the evidence of the existence of Vespers was at The Black Circle when Amy and Dan saw a picture of Winston Churchill making a 'V' with his hands at the Lucian Stronghold. It is also possible that the Vespers control the FBI because when you search Vespers in the FBI database it deletes all your files(confirmed on Cahills vs. Vespers Mission 1).
