Thomas Beckett Camden
Roger de Camden was some sort of a diplomat between the Ventrue and the Cappadocians; his position as Seneschal of London had allowed him to enjoy the riches of the city and experiment with dead corpses at will. He was also a proficient architect and engineer, constructing several secret havens across London to conduct his experiments. He was trusted enough by Mithras to act as his representative in proceedings with the Founders.
Camden had the theory that death occurs when the soul leaves the body, as such, he was a follower of the Road of Bones, and many other Cappadocians waited for his next discoveries. He believed that perhaps everything his clan has done and found about death may be wrong, so every study about the subject must begin with no assumptions. He was also a proficient historian, believing that Lazarus and Japheth, childer of Cappadocius, had been the same person and managed to decipher the location of Lazarus' haven in Egypt.
Camden was ambushed by several Giovanni in his haven in 1514. He managed to kill six of the attackers, but was overwhelmed and killed. In a letter to Constancia, he made clear that he was tired of being hunted and had accepted the inevitable.
Mithras himself slaughtered the surviving attackers and used their remains to conduct a ritual that would protect the final resting place of his former seneschal.
In Beckett's Jyhad Diary, it is revealed that a vampire calling himself De Camden reappeared in the twenty-tens. How he survived the assassination attempt is not explained, though his necromantic skills are legendary and may have aided in his escape and disappearance. His current agenda is unknown, but he advises the Harbingers of Skulls and Monty Coven, and seems to be on working terms with Angelique. Though he identifies with the Harbingers, he is clearly not one, as he retains the appearance of a Cappadocian.
Camden's name is "Roger de Camden" in Dark Ages: British Isles. In the Giovanni Chronicles he is called "Thomas Becket", and in London by Night he is "Thomas Camden". Finally, in the Encyclopaedia Vampirica, his full name is given as "Lord Thomas Beckett Camden".
