Biography
In the year 5,000,000,023, the Tenth Doctor and Rose Tyler encountered the Duke of Manhattan in a hospital run by the Sisters of Plenitude. He was suffering from Petrifold Regression, a disease that turned its victims to stone. He claimed that he suffered this disease despite having lived a life of charity and abstinence. Due to advances in medicine made by the Sisters, they were able to cure his disease, a cure that would subsequently be lost for another thousand years following the collapse of the order. The Duke was accompanied throughout his stay in hospital by Frau Clovis. He would come to see the Doctor as his good luck charm. (TV: New Earth)
