TARDIS (Playing House)
A dying TARDIS was found by the Twelfth Doctor and Hattie Munroe.
History
Under unknown circumstances, the TARDIS wound up on Earth at an antiques fair where Holly purchased it, unaware of its true nature. As the TARDIS continued to leak artron energy, it began to affect all of Holly's house, its interior dimensions overwriting the house and attracted the Spyrillites. As the TARDIS' rooms continued to leak out, Holly became separated from the family in its myriad of rooms. Despite the damages, the TARDIS' safety protocols remained online as it guided the family to its control room.
The Doctor's TARDIS detected the energy leakage and brought the Twelfth Doctor and Hattie Munroe to investigate, the two traveling through its hodgepodge of rooms. After meeting Holly, the Doctor realised the TARDIS' true nature, realising that its interior dimensions would eventually overwhelm Earth. After reuniting Holly with her family, the Doctor found the control room and sent the TARDIS into the heart of a star so it could die peacefully. (COMIC: Playing House)
