The first season of was privately confirmed on the 28th August, 2019. It will contain a minimum of 15 episodes written, directed, and produced by.

Production
Development of the first season started on the 3rd September, 2019, roughly a week after announced his resignation from The Demon's Light Wiki as an administrator and full time contributor, to start work on his own series titled  which featured his characters Harrison and Piercy Provost as the main protagonists. Both characters were originally created in July 2017 for The Demon's Light series, but they were pulled from the series on the 27th August, 2019, at C.Syde's request.

There were many reasons that led to C.Syde's decision to exit TDL roleplay. One of the reasons was his limited experience as a roleplayer and collaborator. Another reason was the workload of his personal projects, which made it harder and harder to focus his time on TDL roleplay. Other reasons included but were not limited to his declining interest in participating in TDL roleplay, and his declining patience with the memes that he was made to endure.

Shortly before the first season of TDL was concluded, C.Syde publicly declared that he was looking forward to seeing his characters make their debuts as supporting characters, but was disappointed to learn that his characters may end up downgraded to recurring or minor characters, due to the changes made to TDL roleplay, making it unsuitable for his characters to keep the backstories that he had originally written for them. C.Syde's lack of interest and patience in rewriting their backstories eventually proved to be another key factor in quitting TDL roleplay.

Less than two days after his resignation from TDL, C.Syde conceived his idea for what would become The Provost Brothers. The idea was inspired by the backstories that he had written for Harrison and Piercy for TDL, but were changed to feature original characters created specifically for TPB. The series was originally going to be called "The Devil's Spark" but was changed to "The Provost Brothers" as "The Devil's Spark" title had already been taken.

The story for the first season was originally going to contain devils with little or no mention of demons, but was changed to fit the official definition of "devil".
