The Vault (The Scales of Injustice)

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)

History
Pale Man ran it in the early 1970s. It was located in Cheviot Hills in Northumberland (PROSE: The Scales of Injustice) 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)

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.
