Embraced two centuries ago in Boston, he was an officer of the invading British army critically injured in battle and left dying on the battlefield. His sire's only reason for chosing him was the frantic prayers he gave to God for absolution. The elder gave him the blood and then carefully watched him as he scoured the battlefield, feeding on the other wounded, and then through the torture of his change. Brought to the brink of insanity, he found a strange peace of mind once it was over and it was then that his sire revealed himself, telling him that the war he had fought in was only the tip of the iceberg and that it concealed a much older and broader conflict that had never really ceased. He taught him of the short history of the Sabbat and the struggle of those who would be free against oppression. Brown listened, not understanding why he was chosen. It became clear after the next few nights, when he learned that the war was really begun to conceal this other war, that his death would not have served King and Country, but the desires of an elder creature with no ties to humanity.
The lesson was well learned, as were the other afterwards. He became an agent of information, following British forces and learning of the kindred with them and their movements. He also shared his extensive knowledge of military tactics with the rather disorganized Sabbat units, becoming invaluable to the Cardinals as a military advisor. Thus, despite his relative youth, he was given the title of Priscus. Through it all, he retained a strong loyalty to the sect's ideals, as well as his religious convictions, and disapproved of the tendency of the members of the Sabbat to slip into bestiality. He became an informant for the Sabbat Inquisition, reporting the most grave incidences he was privy to after moving on to his new assignments.
With the taking of Atlanta, he became attached to the Cardinal of the Southeast and stayed in his service for several years before being asked to visit New Orleans and help them in their efforts to secure Louisiana. He was also told that the influence of another Priscus, Malena, was growing strong there and that the Cardinal was worried she might have designs on his position. He also noted her religious beliefs, knowing how it would prejudice the old soldier against her. Brown accepted the assignment and left for New Orleans. On arrival, he presented himself to Vicario only a few weeks before his destruction. In the turmoil afterwards, he supported Delacroix's efforts at solidarity and used his influence with the Cardinal to get support for his plan. His help in this and planning the counterattack which claimed Callough won him the trust of Delacroix.
In the nights which followed, he established his network of spies and informers and began to take a close look at the kindred of the city while giving the impression he was gathering intelligence for the eventual assault on Baton Rouge. He quickly came to the conclusion that the Cathari Priscus and her brood were dangerously close to infernalism and called on the Sabbat Inquisition, which send Dennis Miller to investigate. Meanwhile, he's become convinced that Delacroix is the most loyal and reasonable of the three bishops and is pushing to have him declared Archbishop by the Cardinal, who is hesitant to put Malena's grandchilde in charge, estranged or not.
Kenneth has also grown quite fond of the city itself and is looking forward to remaining here throughout the campaign to take the state and, once that is done, Texas for the Sabbat. He's wary, however, of the tenuous political situation he's in and is being very careful not to give any indication of his actual agenda.
Kenneth has changed a lot since he was a British officer. Over the years, his attitude has grown less formal and his sensibilities a bit herder. He has been at campaign for over a century now and has adopted the lifestyle of a career mercenary. Always on his toes, always wary of potential threats, his work in intelligence has also made him somewhat cynical and hardened to the necessity of violence and betrayel.
Kenneth gets along quite well with the Lasombra, whom he finds reasonable and dedicated to the sect (he doesn't begrudge them personal agendas, so long as they don't get in the way). He's wary of the psychopathic Job, whom he expects Dennis to destroy sooner or later. He's even become rather friendly with Delacroix, impressed with the drive of the young, inexperienced bishop and fully expects him to live up to the challenge of governing the city alone.
He's wary of the Serpents, whom he distrusts on general principle due to their manipulative reputation and religious beliefs. He outright dates the Rex Pack and their philosophy of evil, though he's careful not to allow anyone to know it. Lastly, he is unsure what to make of the Samedi. He has never met one of their bloodline before and mistook them, initially, for a Nosferatu line. He still notes similarity in manner and thinks there is a connection, but is nervous of their relationship with the Serpents and what it portends.
He's loyal to the Cardinal, whom he thinks has done a fine job of supporting the war effort. Similarly, he is impressed with the performance of the Archbishop of Memphis and has been urging Delacroix to put aside his rivalries and work with the man to secure the northern half of the state so that they can concentrate on Texas and Alabama.
