Innocence ( audio story ) Innocence was the first story in the " I , Davros " series released by Big Finish Productions . Publisher ' s summary . " I find it fascinating that a living creature would subject itself to such dangerous experimentation . Knowing that it would die . . . " The Kaled and Thal races are at war . No one really remembers why , or when it started , but generations of people on both sides have lost so very much . Born into an influential family is Davros . Now aged sixteen , he is being pulled in various directions — his father wants him to follow tradition and go into the military . His sister has joined the Military Youth . And his scheming , devoted mother wants him to pursue a life of science . But no one seems terribly interested in what Davros himself wants . So he must begin to assert himself , begin to take control over his own life , begin to work towards his destiny . . . Plot . Davros finds himself on trial , placed there by his own creations , the Daleks . He learns that the Daleks want his assistance dealing with a schism among them ; but they are not sure of his utility . He agrees to help , but scorns them for how far they have fallen as they cower on Skaro . He determines to review the past in order to plan their future . He thinks back to his own teenage years , and the everlasting war between the Kaleds and the Thals on Skaro . . . Colonel Nasgard , Davros ' s father , is a high - ranking Kaled military commander . He oversees the execution of a squad of troops who panicked and briefly abandoned their post ; he has no mercy on them . He is witnessed by Captain Brogan , who objects to the waste of life ; he then begins to cough , for he is not well . In the city , his wife , Lady Calcula , who is an assistant to Councillor Quested , debates the war ; she is in favour of it for its social benefits . Quested tells her to cover for him , as he has been summoned to an emergency Council meeting ; he promises to explain later , in his quarters . When he leaves , Calcula is met by Magrantine , who is to be a tutor for her son , Davros ; he asks her to finalize Davros ' s course of study . She sends him to meet with the boy , as only Davros knows where his intellectual preferences lie . Elsewhere , Nasgard ' s sister , Tashek , encounters her niece Yarvell , Davros ’ s sister , who is two years older and on the cusp of adulthood — and the attendant mandatory military service . It becomes clear in their conversation that both Calcula and Nasgard favour Davros , largely disregarding Yarvell . Tashek sends Yarvell to summon Davros , who is loitering by nearby Drammakin Lake . Yarvell finds him swimming in the lake , much to her shock , as they have been told never to swim there ; he scorns her concern , and shows her a rock which is actually the shell of a water creature . She is disgusted , but he muses that the Kaleds must have evolved from such creatures , and may one day evolve back into them . Calcula meets with Quested , and looks over the city . She muses on her political position and her strained relationship with Tashek , who owns the family ' s lakeside villa . Quested states that the war is at a stalemate ; Calcula thinks it has been going nowhere for many years . There may be a spy in their midst , as the Thals seem to know their moves before they make them . Quested suggests that even if no spy exists , it may be useful to invent one . Nasgard summons Brogan to his tent , and reveals that Brogan is now in charge . Nasgard has been relieved of duty and is being summoned home . He reveals that he knows it was because of secret reports sent in by Brogan regarding Nasgard ' s health . Brogan admits it , and claims he is working in the interest of their people , and also of Nasgard himself ; Nasgard claims to love his family , and now he can spend his remaining time with them . Nasgard challenges Brogan to shoot him here , giving him an honourable death as per military protocol , but Brogan refuses . Davros does not like Magrantine , and voices his displeasure at being sent to study under the tutor . Calcula overrules him , but this results in an argument between herself and Tashek , with Yarvell and Davros watching . They are interrupted by the arrival of Nasgard , with Brogan assisting him inside . Tashek sees at once that he is very ill , and asks him to sit down . Davros demands to know when Nasgard will die ; Nasgard welcomes the honesty , and insists he still has some fight left , though this seems to be a front . Brogan joins the argument ; he thinks the war will be ended by political means , but Calcula disagrees , and insists that they must gain tactical advantage over the Thals . Brogan stays for the night due to the late hour . Later , alone with Davros , Nasgard asks why the boy is so quiet ; Davros says that he expected his father to be killed in battle . Davros wants to be a scientist and end the war that way ; Nasgard insists he must be a soldier instead , but at the same time , he tells Davros to follow his own goals . Meanwhile , Yarvell speaks with Brogan , and finds him to be a peaceful man . . . Nasgard argues with Calcula over Davros , accusing her of poisoning the boy ' s mind . She is disdainful toward him , especially when learning that Brogan refused to shoot him . However , she refuses to let Davros be sacrificed to the military to end the war ; she insists that the Kaleds need the war to give them meaning . Tashek catches Davros eavesdropping on the argument ; he says that they never argue so over Yarvell . Tashek observes that Yarvell may be her father ' s daughter , but Davros is not his father ' s son ; and she sends him to bed . Meanwhile , Calcular receives a message from Quested ; the Council has been called into emergency session again , most likely to plan peace negotiations with the Thals . He begs her to come to the city with her family for safety , but she refuses , based on Nasgard ' s poor health . Quested orders Brogan to join him in the morning . In the morning , Nasgard compliments Yarvell on her uniform , and gives her his medals to wear , noting that Davros would not appreciate them . Calcula finds Davros by the lake with a dead bird ; he realises that nothing dies of old age on Skaro , due to the encroaching poisons from the war . Quested meets with Brogan , and concurs that Brogan did the right thing in reporting Nasgard ' s health issues . Calcula takes Davros and Yarvell to Magrantine ; Davros rejoins his studies , but Yarvell leaves with Calcula to attend a meeting at the House of Congress . Calcula demands a daily report of Davros ' s progress . Davros is hostile toward Magrantine , but agrees to a tour of the educational complex . At the villa , Nasgard tells Tashek that he hears a strange noise in the house , but she dismisses the concern . She reasserts his illness , and tells him he has been ill since before Davros ' s birth . . . in fact , he is sterile , and Davros is not his biological child . Both she and Calcula are aware of it ; it is the reason Calcula favours Davros over Yarvell . Nasgard does not want to accept it ; but they are interrupted by the strange noise , which Tashek now hears as well . Before Tashek can reveal the identity of Davros ' s real father , they locate a bomb in the communicator room . . . and are killed in its blast . Magrantine shows Davros to his laboratory , which contains a radiation chamber ; Davros overcomes his animosity toward Magrantine enough to become intrigued by the chamber . Magrantine intends to use it to analyse the effects of radiation on different creatures ; indeed , he already uses live animals for tests . He intends to use sentient test subjects , and compartmentalises his emotions accordingly . He asks Davros if he is ready to make sacrifices for the truth . Yarvell mourns Nasgard ' s death . Brogan tries to comfort her , but is unsuccessful . As she swears vengeance , he comments on the cycle of violence ; she deduces that he is a pacifist , or as he calls it , a " peace activist " . Calcula informs Davros of the murders . With nothing left at the villa , she relocates to the city , near the school and the Council complex . Davros returns to the lab for the opening of the radiation chamber . Quested joins Calcula and discusses the murders , and theorises that the bomb was aimed not at Nasgard , but at Calcula . Davros confers with Magrantine about his past experiments on dangerous plants , which were ordered destroyed by the Council . However , he knows that Magrantime disobeyed . They open the radiation chamber , and are greeted by the smell of burned flesh ; Magrantine explains that the radiation can cause mutations in the subjects , but that the subjects rarely survive . He realises that Davros views such mutation as evolution . They enter the chamber . Calcula finds Yarvell at home , excused from duty for the day in light of the murders . Calcula grows angry , and claims that any display of emotion will be taken as a sign of weakness by her opponents . Calcula suggests that Brogan was responsible for the bomb , and Yarvell lets it slip that Brogan is a pacifist ; Calcula is horrified , and believes he is manipulating Yarvell . She concludes the plot was against their entire family . An air raid siren sounds , and the Council building is evacuated ; Brogan tells Quested that a Kaled missile has been launched into a Thal population centre . It seems to be an automated launch . . . meaning a missile from the Thals was en route first ! The incoming missile is not nuclear , at least , but still , evacuation is warranted . Quested refuses to go . Brogan reveals it is headed for the educational complex . . . where Davros happens to be . The missile strikes , heavily damaging the complex . Magrantine is trapped under some masonry , until Davros pulls him free . Magrantine leads the boy out of the complex . Brogan reports to Quested that the damage was minimal ; he believes a greater attack is coming . Quested reveals that the Council is planning a protective dome over the city . Calcula arrives and demands to know where Davros is ; Quested reveals that he was seen leaving the complex with Magrantine . She turns on Brogan and accuses him , and reveals that he is a peace activist — a conflict of interests with his duties . Davros and Magrantine rest on a hilltop outside the city . On the other side is a vast desert , with mountains beyond . Magrantine reveals that his son was murdered in that desert . . . by Nasgard . He draws a weapon and points it at Davros , intending to take revenge by killing him . Davros manages to talk him down , and tempts him with the promise of his prodigious scientific mind . Magrantine gives in , and Davros takes the gun ; they start back toward the city . Quested suggests merging resources with Calcula for her safety , as the spy is still at large . She insists that Brogan is the spy , though Quested argues against it . Calcula insists that this is the reason why Brogan defied protocol and refused to shoot Nasgard — so that he would gain access to their home to plant the bomb and remove the entire family . Magrantine and Davros find the lab somehow intact . Davros insists the incident on the hill is forgotten ; he suggests using those who are close to death for their experiments . Magrantine agrees , and says that the hospitals will supply test subjects . Some time later , after the first round of experiments on such " volunteers " , Magrantine performs an autopsy on one mutated victim , which has some unrecognisable structures , as Davros points out . However , they will need volunteers from elsewhere , as they have already exhausted the supply from the hospital . Quested and Calcula go to watch an execution , where Yarvell is on the firing squad . The " traitor " being executed is also allegedly involved in the murder of her father and aunt , much to her surprise . Yarvell is further shocked when it is revealed that Brogan is the traitor . She argues with her mother , but is ultimately overruled , and takes her place in the firing squad ; the squad opens fire . Later , Davros meets Yarvell , and argues with her over their mother and the execution . When she speaks in defence of Brogan , Davros brushes her concerns aside , and asks for Brogan ' s body for experimentation . She calls him a monster , and screams that she no longer considers him her brother . Quested thinks that with Brogan gone , they will be able to break the stalemate and end the war . In the meantime , he proposes marriage to Calcula . . . and proposes that Davros should be told that Quested is his real father . Calcula refuses , saying that she will only do so when the time is right . Davros tells Magrantine he could not obtain the body ; but the tutor is not dissuaded , as he prefers a living sample . Davros follows him into the radiation chamber . . . and then locks him in , and turns on the power . As Magrantine bangs on the door and threatens to tell Calcula , Davros leaves to tell her himself . . . that is , to tell her how Magrantine committed suicide in grief for his son . As the argument between Quested and Calcula picks up , she suddenly realises that Quested himself may be the real spy , as he has made a number of missions to the Thal capital in recent years . She realises she sentenced an innocent man to death — and whether or not there really is a spy , Quested is responsible ; after all , he did say that it may be useful to invent a spy if one is not forthcoming . Quested turns the situation on her ; he grabs her and demands to know how many other innocents have died because of her . Davros arrives at that moment and orders him to let her go ; Davros pulls out the gun he took from Magrantine . Quested reveals that he is Davros ' s real father . Davros denies it , and shoots him . Davros escorts Calcula to the lab , and reveals the now - mutated Magrantine , who is alive , but horribly changed . He begs to die , but Davros refuses ; he can be used for more experiments . The air raid siren sounds , but Calcula assures Davros that this is only the beginning .
