Isenfel was a Planet in E-Space. It was covered in ice. The Fifth Doctor, Nyssa, Tegan Jovanka and Vislor Turlough landed there in search for the dimensional interface that the Pik Solus stole. It was a lab experiment to simulate the collapse of E-Space, and ways to keep it constant. (AUDIO: Equilibrium)
