SORDIDE Delta was space station which was making its way to its final destination. It contained Shadow-Space which was used to entertain the passengers whilst on transportation, however its systems were damaged. The Fifth Doctor, Nyssa and Hannah Bartholemew once visited it, and Hannah stayed behind after her rescuing the crew but she was left in a robot-like state. (AUDIO: Masquerade)
