Celestin's TARDIS

From Tardis Wiki, the free Doctor Who reference

Celestin's TARDIS was found in a powerless state by Raven and the Second Doctor on Skaro.

While on Skaro, Raven saw the damaged TARDIS. Later, after encountering the Doctor, she told him about the TARDIS and took him to it. When they found it, the Doctor discovered that its interior dimensions were leaking outside. (AUDIO: The Final Beginning)
