Placement is arbitrary.
On the planet Karn, Maren, leader of the Sisterhood of Karn, discovers that the Sacred Flame has stopped producing the Sisterhood's Elixir of Life. The reason for this is simply a build-up of soot in the Flame's path to the surface from Karn's core. The 4th Doctor and Sarah land on the planet Karn, where they discover that evil renegade Time Lord Morbius, presumed dead, has had his brain preserved by a surgeon, Mehendri Solon. Although the Doctor is unable to prevent Solon from giving Morbius a new body, Morbius is driven over a cliff to his death by the Sisterhood. There is no clear date for this story.
