Battle TARDIS (All Hands on Deck)

A Battle TARDIS (AUDIO: Sphere of Influence) arrived in a flat of the block which was once Coal Hill School, where Susan Foreman lived following the second 22nd century Dalek invasion of Earth, in order to pick her up once she had accepted a request made by the Time Lords via Hypercube to join their war against the Daleks. Its chameleon circuit made it appear in the form of a wardrobe. (AUDIO: All Hands on Deck)

Strato and Veklin were aboard the TARDIS when Susan entered it. (AUDIO: Sphere of Influence)
