Working together with Jack Cabot, Edward is a man always looking out to find people who can handle themselves and who can help further his boss' plans. For centuries, Edward has faithfully served as the liaison between his employers, their other staff and outsiders. He is charged with being the bodyguard, messenger, head of security and righthand man for the centuries-old family, who in return, give him room and board in their villa, located in Beacon Hill.
Edward was originally hired by the Cabot family in November 2058, replacing a previous aide, Daniel. Highly recommended, Edward was groomed as a replacement, gradually eased into managing family affairs ever since his induction. The process was greatly helped by Wilhelmina Cabot, as the notoriously untrusting family matriarch took to young Edward fast. By 2077, Edward became an indispensable asset, integral to the well-being of the family.
When the Great War began, Jack and Deegan secured the Parsons State Insane Asylum from looters and hired a security team to protect archaeologist and family patriarch Lorenzo Cabot, the sole resident of the institution, who is kept in a high-security cell located within the basement of the facility. These measures help to prevent him from being freed by anyone who seeks to exploit his otherworldly powers.
Jack found his father's special serum had made him immune to the effects of radiation, yet Edward, not being part of the family, did not have access to the serum. The constant trips between the asylum and the Cabot house caused him to be heavily exposed to radiation and he fell severely ill. By 2080, Edward's radiation sickness led to his permanent ghoulification. While it subjected him to prejudice, it also meant that Cabots would retain access to his essential skills for as long as necessary. Jack treated his employee's radiation poisoning and managed to keep him alive. This greatly extended his life, making him virtually immortal from natural causes of death, similar to the rest of the Cabots. Given that Edward was instrumental in both maintaining the power grid at Parsons and keeping it secure with a mercenary retinue, this was a development as fortuitous as it was lucky.
As of 2287, Edward, on behalf of Jack, is seeking a new gun to work for the family following a series of unusual events that may end up being their undoing if left unchecked, such as Emogene's disappearance and the theft of an important package by a band of raiders, which resulted in the death of their courier, Ben.
