Watchers (audio story)

 was the second release in The Audio Novels. It was written by Matthew Waterhouse and featured the Fourth Doctor, Adric and the Daleks.

Summary
When the TARDIS is trapped in the Vortex, the Doctor and Adric realise that there is something immensely powerful that is draining time itself from the universe.

The wrecks of other time ships - the products of countless experiments in time - exist in a fused cluster in the Vortex. None of them can escape and many of their crews are dead. As the Doctor tries to free the TARDIS, he and Adric encounter threats from other groups, desperate to escape, including a hostile reptile species, mechanically enhanced cyborgs - and Daleks!

But there is someone from the Doctor's own world who is watching. Someone who will prove useful when this Doctor reaches the end of his life...

Continuity

 * Adric reminisces about Romana's recent departure and meeting Nyssa. (TV: Warriors' Gate, The Keeper of Traken)
 * The Daleks have records of the Doctor's previous regenerations, as well as highlighting his encounters with their creator Davros. (TV: The Daleks, Genesis of the Daleks, Destiny of the Daleks et al.)
 * This story provides some further explanation for the circumstances surrounding the Fourth Doctor's regeneration. When deciding to investigate the God TARDIS, the Doctor passes through a field of dense time, which causes him to age rapidly and become significantly weaker. Once he's brought back to his TARDIS, he is restored back to full strength without having to undergo a regeneration, much to his surprise. However, the process still leaves him greatly weakened and it is doubtful that he will be able to regenerate again should the need arise. This prompts Milady to put in a request with the Department of the Watchers to help prepare for the moment of his regeneration. (TV: Logopolis)
 * The Doctor's being weakened due to his passage through dense time could be the reason behind why he needed to regenerate after falling from the radio telescope shortly after the events of this story while his tenth incarnation was able to fall from a similar height from a speeding spaceship and through a skylight while only sustaining superficial injuries. (TV: Logopolis, The End of Time)
 * Marcel was supposed to die during the 22nd century Dalek invasion of Earth on the 8th of April 2164, but was saved by Milady. (TV: The Dalek Invasion of Earth)
 * Gren's form after his pseudo-regeneration bares a similarity to the Tenth Doctor after The Master suspended his ability to regenerate. (TV: Last of the Time Lords)
 * Milady and Gren met at a diplomatic event on Peladon. (TV: The Monster of Peladon, The Curse of Peladon, et al.)
