The Vault ( UNIT ) The Vault contained alien artefacts and other objects of interest taken by C19 from both before and after the formation of UNIT . ( PROSE : " The Scales of Injustice " ) The Vault was permanently kept dark , as some objects would react with light . ( AUDIO : " Tales from the Vault " ) It was one of several storage facilities supporting the main Black Archive in the Tower of London . ( AUDIO : " The Screaming Skull " ) History . The Vault was initially located in the Cheviot Hills in Northumberland . It was formed by Harold Wilson under the Ministry of Technology , ostensibly to help develop new technologies to enrich British industry : Wilson ' s " white heat of technology " . In truth it located and used alien technology for its own ends , and the MPs who ' d approved of it where unaware of what it did . It was run by a mysterious man called the General , who was in fact Brigadier Lethbridge - Stewart ' s brother James from the Inferno Earth . ( PROSE : " One Cold Step " , " Beast of Fang Rock " , " Mind of Stone " ) Debris from the Shoreditch Incident and WOTAN had been sent to the Vault . ( PROSE : " The Scales of Injustice " ) In the late 1960s , the remaining Yeti and technology left over from the London Event were transferred to the vault , including Anne Travers . ( PROSE : " The Forgotten Son " ) Corpses from the London Event were transferred there as well , so the " web " fungus could be taken off them . ( PROSE : " Beast of Fang Rock " ) A number of other corpses were taken to the Vault after subsequent alien attacks . ( PROSE : " The Scales of Injustice " ) At that point the quartermaster of the vault was Captain Hawkins . ( PROSE : " The Forgotten Son " ) Leonard Harkness was a scientist who worked there during the late 1960s . ( PROSE : " One Cold Step " ) Another scientist who worked alongside Anne was Tim Gambrell , who assisted Anne in running tests on the Om - Tsor and the body of Ed Hill . Anne later revealed to Colonel Lethbridge - Stewart that she was at the Vault to gather information for General Hamilton . The remaining Rutan technology and shuttle pod was sent to the Vault following the events at Fang Rock in May 1969 . ( PROSE : " Beast of Fang Rock " ) Shortly after , Colonel Lethbridge - Stewart and Air Vice Marshal Gilmore uncovered a secret bunker beneath Shoreditch , London , owned by the Vault . It was run by Lieutenant Leslie Johnston , and he was using a captured Professor Travers to control Yeti found in the Underground . Lethbridge - Stewart and Gilmore brought the operation to an end , but Johnston escaped . ( PROSE : " The Dogs of War " ) By the early 1970s , Department C19 had taken over the Vault and forcibly retired James Gore . ( PROSE : " Ashes of the Inferno " ) The Pale Man ran the facility . The Vault ' s items had grown and even included the complete Mars Probe 6 . The Pale Man intended to use the technology within to conquer Earth , and the Vault was raided by the Third Doctor and UNIT . ( PROSE : " The Scales of Injustice " ) Brigadier Lethbridge - Stewart had other personnel inside the Vault following Anne Travers . ( PROSE : " Ashes of the Inferno " ) In later years , UNIT had control over it . The contents of the Vault were moved to the Angel of the North in the 1990s . ( AUDIO : " The Screaming Skull " ) In the 21st century , both Captain Ruth Matheson and Charlie Sato worked there . ( AUDIO : " Tales from the Vault " ) The Master escaped from the Vault after hypnotising Matheson and Sato into letting him escape in his TARDIS . ( AUDIO : " Mastermind " ) Rees later escaped from the Vault after possessing every carcass that had been stored in the Vault , in addition to UNIT soldiers who were sent in to investigate the occurrence . ( AUDIO : " The Screaming Skull " ) Inventory . Items . The vault stored a number of alien life forms , including a de - activated Imperial Dalek from the Shoreditch Incident , a new strain of Venus flytrap found in Rhodesia large enough to catch a rabbit or a small dog ( PROSE : " The Scales of Injustice " ) , fragments of the Xylok crystal from Krakatoa ( TV : " The Lost Boy " , PROSE : " Beast of Fang Rock " ) , and a deactivated Terravore . The Vault was also where the Master was imprisoned when he was captured by UNIT following his escape from the Eye of Harmony . ( AUDIO : " Mastermind " ) . Other organic matter stored were Nestene " blood " , a plague created by the Silurian s , Krynoid pods , and Fruit from Western Australia containing mercurial dioxide due to fallen particles of dust from outer space . Also contained were a few weapons , including Cyber - gun s , Excalibur , and Plastic daffodils . Other items stored in the vault were Meteorite globes from the first Auton invasion , WOTAN , " Mars Probe 6 , " samples of Stahlman ' s ooze , the wreckage from a Sontaran scout ship , an army jacket , a painting , crystal , a wax cylinder , ( AUDIO : " Tales from the Vault " ) , The Master ' s TARDIS ( AUDIO : " Mastermind " ) , and Rees ' skull and music box ( AUDIO : " The Screaming Skull " ) . Bodies . There were also several human bodies sotred in the vault , belonging to George Ratcliffe , Melvin Krimpton , Stephen Weams , Mark Gregory , and George Hibbert . ( PROSE : " The Scales of Injustice " ) Behind the scenes . When Gary Russell , the author of " The Scales of Injustice " , tweeted " Mastermind " writer Jonathan Morris , asking him if the Vault in " Mastermind " was the same as the one from Russell ' s novels , Morris responded , " Possibly , but it ' s now been moved to a secret base under [ the ] Angel of the North " . When he realised Russell ' s C19 Vault was a short distance from the one in " Mastermind " , Morris stated that " it all fits ! " AUDIO : " The Screaming Skull " later gave the in - universe link for this move .
