Ollistra's Battle TARDIS

Cardinal Ollistra owned a Battle TARDIS, which she used to travel during the Last Great Time War.

She used it to reach Synthesis Station, (AUDIO: Day of the Vashta Nerada) and later the Doctor's TARDIS was loaded onto her Battle TARDIS for transport to the Tenacity system. (AUDIO: Echoes of War, The Conscript)
