The Vault (The Scales of Injustice)

The Vault was an underground collection alien artefacts and other objects of interest, located in northern England. (PROSE: The Scales of Injustice, et al.) Originally operated by the Ministry of Technology, (PROSE: Beast of Fang Rock) it came into the control of C19 in the early 1970s (PROSE: The Scales of Injustice) and was later passed on to UNIT. (AUDIO: Tales from the Vault, et al.)

By the 2010s, it was one of several storage facilities supporting the main Black Archive in the Tower of London. (AUDIO: The Screaming Skull)

1960s
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) Gore ensured that his son, Simon, gained employment at the facility. (PROSE: Night of the Intelligence)

Debris from the Shoreditch Incident and WOTAN had been sent to the Vault. (PROSE: The Scales of Injustice)

In 1969, the remaining Robot 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 for study. (PROSE: Beast of Fang Rock) A number of other corpses were taken to the Vault after subsequent alien attacks. (PROSE: The Scales of Injustice)

In 1969, 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)

Brigadier Lethbridge-Stewart had other personnel inside the Vault following Anne Travers. (PROSE: Ashes of the Inferno)

1970s
General Gore built Level 4 in the Vault, which was hidden from official records. There he held technology that would help him penetrate the dimension where the Great Intelligence resided. He had Owain Vine transported their to further these aims. (PROSE: Night of the Intelligence)

Following the summoning of the Great Intelligence, Department C19 took over the Vault and forcibly retired James Gore. (PROSE: Night of the Intelligence, 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)

C19 later retrieved all the hardware and information about TOMTIT and stored it in the Vault. (PROSE: The Quantum Archangel)

In later years, UNIT gained control over the Vault. (AUDIO: The Screaming Skull)

1980s
In 1982, Patrick mentioned UNIT's Vault. (AUDIO: The King of the Dead)

1990s
The contents of the Vault were relocated to another facility nearby in the 1990s. Patricia Haggard acquired the original Vault for PROBE's use afterwards. (PROSE: A Worthy Successor)

2000s
In 2000 UN soldiers packaged up the remaining vials of Cyberon from PKD and transported them to the Vault. The boffins in the Vault told Patricia Haggard of PROBE that gold created some kind of interference between Cyberon and the human nervous system. (PROSE: The Last Dose)

Ruth Matheson began working at the Vault in 2002. (AUDIO: Tales from the Vault)

2010s
In 2011, Charlie Sato joined Ruth Matheson in working at the Vault. (AUDIO: Tales from the Vault) By this time, the Vault had been relocated to beneath the Angel of the North. (AUDIO: The Screaming Skull) The Master escaped from the Vault after hypnotising Matheson and Sato into letting him escape in his TARDIS. (AUDIO: Mastermind)

In 2014, Rees 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)

Petronella Osgood once mentioned the Vault. (AUDIO: Power Cell)

Pre-C19
The Vault contained fragments of crystal from Krakatoa and samples of Om-Tsor

It also held the bodies of Ed Hill, Mike Smith, M Krimpton, Lane, Stephen Weams and Albert Arnold. (PROSE: Beast of Fang Rock)

C19 Ownership
The vault stored a number of alien life forms, including a de-activated Imperial Dalek from the Shoreditch Incident, and a new strain of Venus flytrap found in Rhodesia large enough to catch a rabbit or a small dog. Other organic matter stored were Nestene "blood", a plague created by the Silurians, Krynoid pods, and fruit from Western Australia containing mercurial dioxide due to fallen particles of dust from outer space. (PROSE: The Scales of Injustice)

There were also several human bodies sotred in the vault, belonging to George Ratcliffe, Melvin Krimpton, Stephen Weams, Lane, Mark Gregory, Albert Arnold, Mike Smith, and George Hibbert. (PROSE: The Scales of Injustice)

UNIT Ownership
Under UNIT control, the Vault contained a deactivated Terravore. Also contained were a few weapons, including Cyber-guns, 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)

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)

The Vault was permanently kept dark, as some objects would react with light. (AUDIO: Tales from the Vault)

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.
