After successfully opposing slavery in the pocket-universe of Ecto-Space, K9 and his Mistress are treated to a life of luxury as the revered guests of Emperor Lukor. However, a life of decadence soon pales for the travellers and after making a hurried departure, they discover a society of diseased cave dwellers who are dominated by their unseen masters who they worship as gods. Experience tells the Mistress and K9 that things are not all that they seem, and in a bid to unearth the truth, they place themselves in deadly peril.

The demise of Earth was followed by a period in which there was, effectively, no such thing as the human species; a period in which humanity suddenly found itself released from its heritage, with genetic manipulation and vast tracts of space separating the survivors from everything they’d once been.

It’s now acknowledged that the Great Houses were largely responsible for creating the current shape of history, not simply by interfering in major events (although they may have dabbled) but by engineering the entire framework of history as a single definite structure. What’s less well-known is just how easy it is to access that structure’s foundations. Before the War, it was usual for Great House installations to be linked to the Houses’ “records library”, buried in the framework beneath normal time.

A Cyber War rages throughout the galaxy. The Earth-aligned worlds are fighting for survival against the cold, emotionless might of the Cyber Bloc - an alliance of planets whose inhabitants have undergone cybernetic conversion in the name of racial superiority.

Right from its creation, the secret intelligence service of Great Britain was touched by a streak of ritual: its initiations were usually occult, its codes based on astrological or alchemical ciphers. When Faction Paradox first entered Earth history in the 1700s, the Service took an immediate interest in the new arrivals’ own ritual practices, and in the inevitable feud between British and Faction agents no single figure was as important as Sabbath.

It is the time of the Second World War, and all is not well at a top-secret research base in Greenland. The British have been testing a new device which could bring about a swift end to the war with Germany - but the trials have gone disastrously wrong. When the Professor and Ace arrive, they encounter an isolated community not only under threat from its human enemies, but stalked by a horrifying menace with a voracious appetite for survival.

The death of a nameless traveller on a flight to the volcanic Hedistic islands would seem to have been natural. But when his young friend starts her own murder investigation, she uncovers a plot which threatens the safety of the entire planet....

In medieval Europe, the arrival of two strangers brings mystery and conflict to a peaceful market town. The Inquisition is called for, with the capture of a foreign sailor. He looks like a man, but his clothes and language imply that he may be something more. Or perhaps something less. And what kind of ship sails through the sky? The Inquisition discover that some questions are too dangerous, and some answers too sensitive. Soon, their fate, and that of their prisoner, become bound up with the second visitor to the town. A disgraced former Templar Knight turned wandering mercenary, Guy de Carnac.

"Our planet of Galspar is renowned for the quality of its ice cream, which is shipped across the universe. Life on Galspar is perfect - just as the eyescreens tell us it is. There are those who say that if you look in the right places and ask the right questions, then this perfection is exposed as an illusion, and a terrible conspiracy is uncovered. But there have always been some intent on disruption, who are not happy with the jobs they themselves have selected or with the wide range of freedoms granted by the Company. Ignore these troublemakers, citizen, and you'll see that they do indeed disappear...."

Your ship is at the bottom of the English Channel, your crew are probably dead, and your nearest source of food is in a Loch six hundred miles away. And the natives are insane. Life isn't looking too promising for a Zygon called Bobby. Victorian London is not a great place to be if you're a wounded shape-shifting alien.

For more than 80 years, the British Government has been keeping something hidden. Now it can no longer be kept secret. With a Weapons Crisis Committee standing in Geneva, Captain Alice Wells of UNIT is given the task of investigating the mysterious deaths of allied and UN troops. When her investigation leads her to an ultra secure safe house in England she discovers just what it was that the government thought too dangerous to be made public...a Sontaran!

Treachery is afoot on the Genesis, a cargo ship travelling at the very edge of Human space. When Silvia Tanner opens herself up for "a bit of honest corruption" with the Sontarans, she soon finds she has bitten off more than she can chew. With a Sontaran aboard, and the sudden unexpected arrival of an investigator calling himself 'Alex', the stakes are suddenly raised even higher than before, and secrets will out.

It is a time of restoration. Ten millenia have passed since the solar flares devastated the planet Earth and now humanity has come home to reclaim and rebuild. But scientists at Mombassa Station are about to resurrect a deadly menace that was once destroyed. A menace that will stretch from the depths of the African continent, to the ancient and decaying Nerva Beacon still orbiting high above. Can a small group of Gene-techs hope to survive the rush of Race Memory?

Era: Human historical (later period). Technology: Military (self-contained), non-time-active. By the end of the fifth millennium AD, the homunculi created by the human species - clones, cross-breeds, fighting-machines and artificial intelligences of all descriptions - outnumbered humanity by more than thirteen to one: But even so, there were no creations like those of Peking. Heading a 1,000-strong army of individually-crafted automata, the 12 commanders were self-aware embodiments of the oriental zodiac, forged to a strict astrological design, and said to incorporate history itself in their operating program.

PRIMEra: Last thirteen million years. Technology: Military (blatant), limited time-awareness. It’s perhaps unwise to think of the Sontarans as a species, as such. A homunculus breed hatched by the million and engineered for full-engagement warfare, the Sontaran military machine is regarded by many time-active cultures as an “occupational hazard”: a force of nature rather than a race, compelled by duty and genetics to acquire new technologies for its endless war effort. It should be remembered, however, that with the backing of a higher power even the crudest of breeds can become something quite different.
