David Kilkerman a member of the Inner Sanctum of the Templar Order and is an employee of Abstergo Industries, who was included within a carbon-copy of an email from Warren Vidic to Alan Rikkin – alongside - Nancy Nilop – which discussed Daniel Cross' return to the Templar company in Philadelphia, upon instinctively killing the Mentor in 2000.
He was also present alongside Alan Rikkin and Henry Liman when the former was speaking to Warren Vidic after Desmond Miles had finished reliving the memories of Altaïr Ibn-La'Ahad in 2012.After the death of Warren Vidic, David became the new head of the Animus Project.
In October 2016, he was present during the induction of Simon Hathaway into the Inner Sanctum. Ten days later, Kilkerman sided with Rikkin against Hathaway when charges of treason were brought against their fellow Templar. However, only backed by Kilkerman, Stearns and Gramática, Rikkin had no choices but to drop the charges.
In March 2017, the Inner Sanctum invited the new Black Cross to a meeting in Quebec, during which David was present. Displeased that he auto-proclamed himself their inquisitor, they threatened him and demanded to know his identity. The masked man responded that he came only as a courtesy, to inform them that he was investigating an hostile fifth column within the Order. After affirming his independance, the Black Cross dropped a smoke bomb and disappeared.
