It was written by Marc Platt and featured Susan . It was the first story of a Companion Chronicles trilogy released by Big Finish Productions in November 2013 — January 2014 to celebrate the 50th anniversary of the show . This trilogy was centred around the character of Quadrigger Stoyn introduced in this story and was continued with " The Dying Light " and " Luna Romana " . This story marks the maiden voyage of the Doctor inside a Type 40 TARDIS he chose to steal and the day both he and Susan fled from Gallifrey . For the Doctor , it was the moment he began what would inadvertently become an enormously long career of travelling through space and time . It also marked his first visit to the solar system and his first interaction with humans . Publisher ' s summary . When the First Doctor and his granddaughter Susan escape through the cloisters of Gallifrey to an old Type 40 Time Travel capsule , little do they realise the adventures that lie ahead . . . And little do they know , as the TARDIS dematerialises and they leave their home world behind , there is someone else aboard the ship . He is Quadrigger Stoyn , and he is very unhappy . . . Plot . The First Flight ( 1 ) . On Gallifrey , the Doctor and Susan are being pursued by several armed guards through a TARDIS repair shop . Determined to leave their home , the Doctor and Susan steal a faulty old TARDIS , although the Doctor has very limited knowledge on how to properly operate one . Upon escaping Gallifrey , the TARDIS materialises in the Sol system , near a planet that Susan recognises as Earth . They soon realise , however , that their escape has completely depleted the TARDIS ' s faulty old engines , leaving them with seemingly no way home . They then realise that they are not alone on the TARDIS , as another Time Lord named Quadrigger Stoyn was also aboard the ship , taking apart the engine so that this TARDIS could be scrapped . Stoyn is upset at the Doctor and Susan for stealing the TARDIS with him aboard it , and is further distressed when the Doctor destroys the TARDIS ' s homing device so that the Time Lords cannot find them , leaving them stranded with no way to get home . Despite Stoyn ' s protestations , the Doctor and Susan step outside to explore the planet — with the Doctor taking the TARDIS ' s dematerialisation circuit as insurance — finding it to be in its primeval era with only the most primitive forms of life . With Stoyn following them , the Doctor and Susan eventually find that the planet is indeed inhabited by a form of intelligent life : a race of glob - like beings called Archaeon s . One of the Archaeons , known simply as the First Propagator , welcomes the Doctor , Susan , and Stoyn , and shows great curiosity about them . The three of them are led to an enormous cavern housing a strange cannon - like device that shoots red lightning at the planet ' s moon , seeding life on it . When the Doctor realises that they are interfering with the development of this planet ' s life he immediately protests , an action that the Archaeons consider to be heresy . As this goes on , the Archaeons begin disassembling the TARDIS , causing the stasis field to destabilise , forming a breach in space and time . Red Lightning ( 2 ) . Susan awakes to find herself in a hospital run by human s , where she learns that she was found in a 450 million year old archaeological dig site . As she is being questioned , she can faintly hear the Doctor ' s voice coming from somewhere . She eventually realises that the she is on Earth ' s moon , and the Archaeons had actually been seeding life on Earth itself . While being transported to the nearby Giant Leap Base , Stoyn mentally projects himself to Susan , claiming that he ' s trying to bring her and her grandfather back , but Susan does not believe him and refuses to cooperate . Stoyn is then interrupted as the lunar rover that Susan is being transported on is assaulted by red lightning , like the kind the Archaeons were using . Eventually Susan finds that the Doctor is in the next bed over from her . After waking him up , she explores the rest of the lunar rover only to find that the crew are all dead , killed by some sort of strange parasites . As the Doctor tries to make sense of this all , he realises that the stasis field must have frozen him and Susan in time until they were recovered by the human archaeologists . Stoyn manages to get in touch with them once more through the rover ' s communication devices , telling them that they need to come back and that the Archaeons are very angry with them for ruining their experiment . The Doctor attempts to warn the humans back at the moon base , but the link is cut off by more of the red lightning , knocking out the power at the base . While the Doctor and Susan contemplate their next move , they are again contacted by Stoyn , who pleads with them to come back so they can all escape , but the Doctor refuses . Eventually they are taken back to the cavern by the Archaeons by force . Upon returning , the Doctor congratulates the Archaeons on creating such a beautiful world full of vibrant life . However , the First Propagator says that their experiment was a failure due to their interference and as a result Earth has become a disorderly mess of chaos . With Stoyn ' s testimony against them , the Archeaons lay the blame of their failed experiment on the Doctor and Susan and decide to purge the Earth . As the Archaeons fire upon Earth , Stoyn leads the Doctor and Susan back to the TARDIS , its engines now fully regenerated , where he tries to convince the Doctor to give him the dematerialisation circuit . As they argue , they come to realise that the humans are launching a retaliatory missile strike at the Archaeons . The Archaeons ' power begins to fail , at which point the Doctor decides to help them , thinking that the Time Lords will look more favourably upon them for restoring order when they catch up with them . The Doctor and Stoyn convince the Archaeons to let them use the TARDIS to power up their systems . When the Doctor refuses to turn the dematerialisation circuit over to Stoyn , he takes Susan as his hostage , offering to take her with him in the TARDIS , leaving the Doctor to face judgment at the hands of the Archaeons . As the Archaeons prepare to resume their bombardment , the Doctor cuts the cable , leaving the Archaeons defenceless . Susan gets away from Stoyn and runs back into the TARDIS where they close the doors on him . Stoyn begs to be let into the TARDIS , but both the Doctor and Susan decide it best to leave him behind . Stoyn vows to get his revenge on the Doctor . As the TARDIS dematerialises , the Doctor and Susan see that the Archaeons ' weapon has been destroyed by a direct hit from the humans , leaving them defenceless . Still impressed by the Earth and its history , the Doctor attempts to make the TARDIS take them back to Earth . Instead , they end up on an alien planet , causing the Doctor , in his excitement , to forget all about Earth at the moment .
