Sabotage! The TARDIS is breaking up! Thanks to the combined efforts of the treacherous Turlough and his evil master, the Black Guardian, the Doctor and his companions are in terrible danger. The outside world has begun to break through and Nyssa has disappeared. Can the TARDIS’ fail safe mechanism save them all by docking with another ship?
Unlikely, when the nearest vessel is a carrier of plague victims destined for the infamous Terminus, the time-bomb planet ticking at the centre of the universe…
- This is the second part of the Black Guardian Trilogy, which began in Mawdryn Undead and continues in Enlightenment.
- Nyssa meets the Doctor in her future (though his past) in Asylum.
- Nyssa also meets the Doctor at the end of his fifth regeneration in Winter.
- A second explanation for the Big Bang is given in Slipback.
- Turlough is given Adric‘s room in the TARDIS.
- When the TARDIS is threatened with break-up, it will attempt to lock onto the nearest safe place in space-time (in this case, a starliner), to allow its passengers to escape. The Doctor claims it has always had this protocol, but it’s never worked before.
