Origin

Dunwich Sanatorium is a mental hospital, that quickly became a front to churn out hit men and assassins for gangsters and corrupt government officials. Then Algernon Rottwell was admitted to this sanatorium, where the doctors dubbed him as "incurable". Shortly afterwards, Rottwell started a riot and used the ensuing chaos to take control of the place. He then became known as Doctor Rottwell and carried out countless depraved, twisted experiments here, soon earning him the nickname of "Doctor Rot".
