Terminus (TV story)

Synopsis
The TARDIS attaches itself to a space liner after Turlough, still under the Black Guardian's influence, damages its controls. The Doctor and Nyssa meet two space pirates, Kari and Olvir, who have come on board the liner in search of plunder, while Tegan and Turlough get lost in the infrastructure.

The liner docks with what appears to be a hulk floating in space. This is Terminus, which claims to offer a cure for Lazar's Disease. It is crewed by a group of armoured slave workers, the Vanir, while the cure is administered by a huge dog-like creature known as the Garm. Nyssa, who has contracted the disease from sufferers transported aboard the liner, discovers that the cure - involving exposure to radiation - does actually work.

The Doctor and Kari meanwhile learn that the ship, once capable of time travel, was responsible for the creation of the universe when an ejection of fuel from one of its engines caused the 'big bang'. Aided by Kari and the Garm, the Doctor is able to disconnect a still active but damaged engine that is on the point of exploding - something that could result in the universe's destruction.

Part One
Under the direction of the Black Guardian, Turlough manipulates some of the TARDIS's circuitry in a corridor. Hearing Teagan approach, he hurriedly shuts the roundel we was working behind. Teagan still suspicious of the new companion, finds him and questions him, her mistrust only exacerbated by the roundel falling open again. While Turlough tries to turn on the charm, Teagan shows him to his room, formerly Adric's.

Once Teagan has left, to find Nyssa and complain about his obnoxious personality, Turlough heads to the console room to remove the space-time element from beneath the console. The Black Guardian appears on the scanner screen to encourage his obedience, despite his doubts that the Guardian will preserve his life. While Turlough is unable to remove the element, his sabotage causes the TARDIS to begin breaking up.

Teagan sees one of the fractures in the corridor, and runs to find the Doctor. Another fracture appears in Nyssa's quarters. While the Doctor frantically tries to save the TARDIS, the fracture in Nyssa's room resolves into a door with a mysterious skull logo on it. Deciding that the unknown on the other side of the door is better than the certain death in her room, the Doctor tells her to run through the door.

The Doctor, Teagan, and Turlough run to Nyssa's quarters, and the Doctor throws a chair into the door to keep it from closing and severing the link to the space vessel that the TARDIS, engaging an emergency system, has locked onto. The trio crawl through the door to pursue Nyssa, only to have it close behind Turlough.

The Doctor goes on ahead to find Nyssa, while Teagan and Turlough stay behind. Meanwhile, two space pirates, Kari and Olvir, board the ship and make their way to the bridge, finding it deserted and running on automatic. Hearing a sound she believes to be Nyssa, Teagan drags Turlough to find her. Instead, they find a locked door through which robed arms try to grab Teagan.

On the bridge, Kari and Olvir have taken the Doctor and Nyssa prisoner, believing them to be rival pirates. Unexpectedly, Kari and Olvir's ship undocks and accelerates away. While Kari tries, first by force and then by negotiation, to persuade the Doctor to take them with him, a computer voice suddenly comes to life, announcing that they are soon to dock at Terminus, and all passengers should disembark to avoid an imminent sterilization.

Olvir realizes what this means: the passengers locked in their rooms all have Lazar's disease, and they are trapped on a plague ship.

Part Two
As the ship docks with Terminus, Turlough and Teagan take shelter under a grating in the floor of the corridor to escape the diseased Lazars. The Doctor warns Nyssa not to touch the Lazars, and stops Kari from shooting them. The three of them head to the bridge to find Olvir. Nyssa finds him cowering behind a chair.

While Teagan finds a ladder out of the underdecks, Turlough hears the voice of the Black Guardian warning him not to fail in assassinating the Doctor. On the bridge, Olvir explains that his sister died from Lazar's disease. He tells them that Terminus is run by a private company, for profit, that uses fear of the disease to demonize the plague victims. While they claim to offer a cure at Terminus, he's never heard of anyone coming back. The Doctor, meanwhile, is stunned to discover Terminus is in the center of the known universe.

Teagan and Turlough, still under the floor, see an armored man patrolling the deck. He gives an order: "Sterilize!"

Within Terminus, Bor is studying a display and muttering, "The reading's still climbing." Valgard, the armored man from the ship, enters and is horrified to see Bor crossing a line demarcated on the floor. He goes to follow, but stops at the line. Instead, he reports to his commander, Elrak, that Bor has entered the Forbidden Zone, only to be horrified at Elrak's insensitivity and fatalism at their situation.

On the bridge, the computer warns that sterilization is imminent. Noxious gas flows through the underdecks where Teagan and Turlough are still trapped. The Doctor's entourage on the bridge decide to try to find the entrance to the TARDIS. Nyssa begins to feel feverish, necessitating the removal of her skirt. Realizing that she's infected, Olvir recoils, only to see her dragged away by a robotic drone.

Nyssa is brought to Valgard, who is complaining to a compatriot about Elrak's insensitivity. Referring to himself as a "baggage handler", Valgard himself is insensitive to the plight of the Lazars, caring only for the Hydromel on board the ship. While his associate retrieves the Hydromel (stealing a vial to insert in his armor), Nyssa attempts to flee Valgard. Unknowingly, she gives Olvir a chance to slip aboard Terminus. Valgard takes her to meet the Garm. Shortly afterwards, the Doctor finds Nyssa's skirt.

Elrak, resigned to Bor's death, has Valgard call the Garm to insure that Bor's armor is recovered. The Garm, a mute, dog-like creature that dwarfs Valgard, is summoned by a small call box and emerges from the Forbidden Zone.

Leaving Turlough and Teagan to escape sterilization, the Doctor and Kari flee to Terminus, unknowingly observed by Valgard. He knocks Kari out, then grabs the Doctor by the knock and begins to squeeze...

Story Notes

 * This is the first instance of the Doctor being able to 'spy' on his companions using the TARDIS scanner.
 * This story has one of three descriptions of how the universe started, the others are in DW: Castrovalva and BBCR: Slipback (although the canonicity of the second could be debated). As the exact fuel used by Terminus is never mentioned, but apparently produces radiation as a side-effect of energy generation, it's not implausible to believe that Terminus is fusion-powered by hydrogen, and its release of fuel and the in-rush of hydrogen mentioned in Castrovalva are the same event.
 * This story is well-remembered for its scenes in which the conservative Nyssa gradually removes some of her clothes, leaving her in little more than a shift by the story's end.
 * The name "Vanir" comes from Norse mythology and refers to a tribe of gods who made war on the rest. Many of the Vanir characters in Terminus are given names with a Scandinavian sound to them.

Discontinuity, Plot Holes, Errors

 * If the Doctor is correct that Terminus created the universe while time traveling, then the entire universe is a predestination paradox.
 * Why would the TARDIS, while travelling in the vortex (i.e. outside of space and time), lock onto a conventional spaceship, that is within the universe, in the event of catastrophic break-up? The disaster caused the TARDIS to drop back into 'real' space and the Terminus transport ship happened to be the nearest one at the time.
 * The origin of the Terminus station is left a little unclear. What was its original function? How did its original pilot/owners and their ability to travel in time get forgotten? How did it come into the possession of Termius Inc? It originally belonged to some alien race. It's pilot was killed in the way postulated by the Doctor. It was found floating in space as a derelict and salvaged by Terminus Inc., and partially adapted for their needs. They then installed the Garm and the Vanir, without bothering to make a full check of the interior due to the radiation levels in the forbidden zone, and because they didn't really care what happened to the Lazars.
 * Why would the explosion of Terminus' second engine destroy the universe? While it might well have acted as the catalyst for the big bang at the beginning of the universe, if the same thing happened now, wouldn't it just be a matter of fuel exploding harmlessly in space? There is a dimensional instabilty at the precise centre of the universe as a result of the first explosion, combined with effects of Terminus' uncontrolled timejump into the future. Hence a second explosion in the exact same spot and of the same type, would destabilize the whole time/space continuum.
 * How does Turlough's tampering with the electronics on board the transport ship at the climax of episode three, lead to the triggering of the automated fuel-dumping proceedure within the Terminus control room, in the forbidden zone? It doesn't. It is just a coincidence that the two events occur simultaneously.
 * Though not strictly speaking an error, it is however obvious that there are not enough lines to go around the four principles. Tegan and Turlough spend almost the entire story trapped in the bowels of the transport ship.

Continuity

 * This is the second story in the "Black Guardian" Trilogy, which ends with DW: Enlightenment.
 * Nyssa meets the Doctor in her future (though his past) in PDA: Asylum.
 * Nyssa also meets the Doctor at the end of his fifth regeneration in BFA: Circular Time.
 * Turlough is given Adric's room in the TARDIS: there are visual references to DW: Kinda (the double helix), The Visitation (the android's mask) and Logopolis'' (the star chart).
 * The Black Guardian refers to the space-time element as "the heart of the TARDIS". The "heart" of the TARDIS would be later important to the plots of DW: Boom Town and The Parting of Ways, where it would be shown as an intense light.
