The Ship (Shada)

The Ship was a sentient spaceship designed by the Drornidian scientist Skagra.

History
Though originally a regular spacecraft, and a worshipful servant of Skagra, the Ship was convinced by the 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.

After Skagra's plans for the Universal Mind were foiled, the Ship trapped him in her brig and, ignoring her former master's begging to be freed, offered to tell him all about the Doctor, (TV: Shada) as well as forcing Skagra to watch seemingly endless video reports about the Doctor's life, in chronological order. (PROSE:Shada)

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