Surely Tegan must have made a mistake when she set the TARDIS’ co-ordinates, because The Doctor certainly hadn’t intended landing on Manussa? But upon learning that Manussa was once home of the Sumaran Empire, The Doctor knows that their arrival has been no accident but has been orchestrated by a hostile force – a force which is rapidly gaining control of Tegan’s will. By first infiltrating Tegan’s subconscious mind, through strange and disturbing dreams dominated by the image of a huge snake’s skull, this force – the Mara – is planning on as a vehicle for its return to power on the planet Manussa.

So just as Manussa prepares festivities to commemorate the destruction of the Sumaran Empire by the ruling Federation, it seems that the Legend of the Mara could be about to come true.

According to this Legend, the Mara was never destroyed by the Federation but merely banished. Furthermore, the Legend claims that the Mara will return in a dream – a precursor to its gaining control of all their minds… It is clear to The Doctor that the first steps in the Mara’s return have already been taken..


  • This is the first part of the Black Guardian Trilogy, which continues in Terminus and concludes in Enlightenment.
  • Tegan is still wondering if she’ll be free of the Mara.
  • Tegan knows a great deal about transmats.

  • Turlough’s origins are finally explained in his final adventure aboard the TARDIS. (Planet of Fire)
  • In Part Two, when the Fifth Doctor tries to jog the Brigadier’s memory, the Brigadier sees flashbacks of himself when he was at UNIT (The Three Doctors), a Yeti (The Web of Fear), a Cyberman (The Invasion), the Second Doctor (The Invasion), an Axon (The Claws of Axos), the Daleks (Day of the Daleks), the Third Doctor (Spearhead from Space), the First Doctor (The Three Doctors), the Robot K1 (Robot), a Zygon (Terror of the Zygons) and the Fourth Doctor (Terror of the Zygons).
  • This isn’t the only occasion where a companion shall meet another version of themselves, in Father’s Day the Ninth Doctor’s companion Rose sees herself as a baby, although there the results when the two versions come in contact are far more dangerous.
