The Ship was a sentient spaceship designed by the Drornidian scientist Skagra.
- You may be looking for the Doctor's TARDIS or the last hope of Sarath.
Though originally a regular spacecraft, and a worshipful servant of Skagra, the Ship was convinced by the Fourth Doctor to redesign some of her own circuitry, which resulted in her losing her nigh-religious faith in Skagra (eventually even turning against him) and gaining the ability to dematerialise and travel through the Time Vortex, much like a TARDIS.

When speaking to her pilot, the Ship presented a holographic interface resembling the outline of a humanoid woman's face. (WC: Shada)
