Image of the Fendahl is the third serial of the 15th season of the British science fiction television series Doctor Who, which was first broadcast in four weekly parts on BBC1 from 29 October to 19 November 1977. The serial was Chris Boucher's third and final script for the series and is set in an English priory, where the cultist Max Stael (Scott Fredericks) prepares the scientist Thea Ransome (Wanda Ventham) to be possessed and transformed by an ancient gestalt alien called a Fendahl. Plot In a priory near the village of Fetchborough, four scientists, Adam Colby, Max Stael, Thea Ransome and Dr. Fendelman, are doing tests on a human skull they found in Kenya, apparently twelve million years old. When Dr. Fendelman starts using a sonic time scan, trying to get an image of the owner of the skull, the skull itself seems to react, locking onto Thea and releasing something in the priory grounds that kills a passing hiker, who eventually totally disintegrates. The scan catches the attention of the Fourth Doctor and Leela when they are pulled down to Earth by it. They set off to find it before it creates a continuum implosion and destroys the planet. They separate and Leela finds the cottage of ‘Mother’ Tyler, a local modern-day witch gifted with psychic powers. The Doctor ends up narrowly avoiding death at the hands of the creature created by the skull, which then kills the leader of a detachment of guards Fendelman has brought in after the death of the hiker, sealing everyone into the priory. Ma Tyler then encounters the creature but survives and is saved from going into psychic shock by the Doctor, who by this time has worked out that the thing is a Fendahleen, a creature from his planet's mythology, supposedly destroyed when the Fifth Planet broke up. He makes his way into the priory and finds the skull, which tries to kill him. Leela saves him and they go off to the Fifth Planet, only to find that the Time Lords sealed the planet in a Time Loop, making all proper records invisible even to them. Thea, meanwhile, has been gradually converted into the new core of the Fendahl, a creature that feeds off life energy and leaves nothing behind. Stael, leader of the local black magic cult, recognises this and believes he can control the Fendahl and use it
