Space trading post located on the dark side of SVARTOS. It was owned and controlled by the merciless Kane. A living mechanoid in the shape of a dragon roamed its depths. The Seventh Doctor discovered that the Dragon's body hid a powerful energy crystal known as "Dragonfire". He also found that Iceworld was in reality a huge spaceship which needed the dragonfire to start up again. After Kane's suicide, Iceworld fell into the possession of Glitz, who rechristened it Nosferatu II (7G).
