The Vault is located under the Angel of the North.
Within the Vault is a hunk of what is thought to be a Sontaran scout ship that crashed at Tunguska province.

This audio drama features a cast of six actors, more than any other Companion Chronicle release to date.
This is the second Companion Chronicles release to feature multiple companions from different eras, the first being The Three Companions. There are in fact six companions involved in the story, although only four are heard. This is not an omnibus of stories with linking material, but rather Jo, Romana, Steven and Zoe are worked into the narrative by way of archival recordings.
The events involving Jo are said to take place "70-odd" years after the death of Tommy Watkins in 1900, placing the Doctor's exile on Earth in the early 1970s. This is consistent with the TV: Mawdryn Undead version of the UNIT dating controversy and the real life broadcasts.
This audio drama was primarily recorded on 11 November 2010, however according to the interview included on the CD, contributions from some cast members were recorded during sessions for other Companion Chronicles.
This was Mary Tamm's final appearance in The Companion Chronicles before her death on 24 July 2012.
