Muldwych Muldwych was an incarnation of the Doctor who spent over five centuries exiled on Antýkhon , the name given to Earth during a period of its history when it was inhabited by Hairies and the Charrl . He was occasionally visited by the Seventh Doctor . He liked to put whisky in his tea . ( PROSE : " Birthright " ) Biography . Due to his own actions , Muldwych lost his TARDIS and became trapped on Earth sometime before the year 16909 . He built a hut at the top of Mount Kukúrk in Africa . The Charrl came to Antýkhon to establish a new homeworld but found that it was too polluted and hot for their long - term survival . They did not have enough energy to leave the planet in their gravity ship s , so they were forced to stay . As the years passed , Muldwych helped the Charrl and became a trusted ally . During this time , Muldwych began manipulating events so that he would eventually escape Antýkhon . Ch ' tizz , the queen of the Charrl , made a nine - day journey to Muldwych ' s hut . She proposed that Muldwych help guide the Charrl to create a temporal link between Antýkhon and a more suitable period of Earth ' s history . Planning on using this link to escape , Muldwych agreed . For 500 years , Muldwych guided the Charrl chronomancers . He helped them hone into the Great Divide and create a link to Russia in 1908 . Several Charrl were sent through the Divide but were all fatally injured by the journey . After seven months , the Divide moved to London ' s East End in 1909 . Shortly afterwards , Muldwych was visited by the Seventh Doctor . Muldwych asked his younger self for help , but the Doctor refused due to the first law of time . Knowing Ace ' s eventual fate , Muldwych gave the Doctor a present for her : " Madame Bovary " , a 19th century French novel . The Doctor was aware that Muldwych needed a TARDIS to stabilise the Divide , so he split his in two and sent the halves to the two sides of the Divide . The half carrying Ace landed in Antýkhon and was quickly retrieved by Muldwych after Ace left it . Muldwych needed the TARDIS to be complete to stabilise the Divide and went through it with Ace , Seeba , and Korin . They landed in Hanbury Street and met up with Bernice Summerfield . Muldwych reunited the two parts and the Divide was stabilised , letting all the Charrl come to 1909 . With the TARDIS complete , Muldwych told the Charrl that they couldn ' t take over Earth in 1909 . He told the Charrl he would take them to an alternate Earth where humanity never evolved , but he actually took them to an unused part of the Seventh Doctor ' s TARDIS . With the Charrl gone , Muldwych could finally reach the goal of his master plan : to use the Seventh Doctor ' s TARDIS to escape Earth . However , after Muldwych set the TARDIS to dematerialise , the TARDIS sent Mukdwych back to Antýkhon . Shortly afterwards , the Seventh Doctor visited Muldwych and shared a cup of tea with him . ( PROSE : " Birthright " ) Muldwych managed to escape Antýkhon when Time , Pain , and came to Bernice Summerfield and Jason Kane ' s wedding through Puterspace . Using " a narrow beam of chronon s perfectly aligned with the marginal reality established by the Puterspace apparatus " , Muldwych came to Cheldon Bonniface on 24 April 2010 . Along the way , he found himself In another marginal reality and met and befriended a Unicorn named . At the wedding , he gave the Seventh Doctor two halves of a time ring to use as the wedding rings . He also gave the Doctor the book " The Unformed Heart " . ( PROSE : " Happy Endings " ) Appearance . Muldwych had a plump figure and a ruddy face . During his exile , his hair was grey - brown , ( PROSE : " Birthright " ) while after his exile , it was mostly grey with streaks of red . He wore a white robe ( PROSE : " Happy Endings " ) and had a blue Roman - style ring on his left hand . ( PROSE : " Birthright " ) Other References .
