On the return trip from Velyshaa , Siy Tarkov and the crew of the star yacht " Crusader " were infected with the Neutrotransmitter Failure Syndrome ( NFS ) plague when they stopped at Scalanis V to refuel . Over the next twenty years , it spread throughout the Border Worlds , killing millions , resulting in the declaration of a galactic state of emergency . The origin of the NFS plague is unknown . Commander Frey Saxton , the leader of the Graxis Wardens , believes that the native primates on Graxis Major are evolving . However , her second - in - command , Dan Culver , is more sceptical . The Wardens ' latest recruit , Kaymee Arnod , arrives on the planet on Saxton ' s birthday . Kaymee , who had been descending to the surface of Graxis Major in free - fall in a space suit , followed the wrong descent trajectory and arrived in the wrong location . This occurred because of a collision in her descent . Shortly before being rescued by Warden Telligan , Kaymee hears the sound of an energy blast followed by a scream . The Wardens are baffled by the makeshift nature of the leaf bandage around Kaymee ' s injured leg . They seem to have been applied by one of the native primates , who are not believed to be intelligent enough to do so . The Galactic Union ' s operational security commander , Georgi Selestru , tells Galanar that Tarkov ' s warning of a Dalek invasion was buried away by the Galactic Union Council . They wanted to maintain a peaceful galaxy and to prevent another Great Catastrophe . Selestru ' s interest was piqued when a race calling themselves the Daleks offered assistance to the inhabitants of the Scalanis system in developing Variant 7 , a possible cure to the NFS plague . The " Crusader " was eventually found drifting in space , more than twenty years after Tarkov had set off from Velshyaa . By this time , he was the only survivor of the crew . It took another two years to transport his cryo - pod to Galactic Union HQ Planet Nine , having been passed from ship to ship in the interim . However , it is unknown who actually discovered the " Crusader " . The Border Worlds are governed by the Border Worlds Confederation Cabinet . One of its representatives , Provost Carneill , is working for the Daleks , who dismiss Warden Harley ' s death on Graxis Major as an " unfortunate accident " . They claim that their main priority is to cure the NFS plague and save millions or billions of lives . Saxton determines that the Wardens are no longer alone on Graxis Major . The object which collided with Kaymee during her descent was not the Wardens ' jet as Kaymee originally believed . Further evidence of this is provided by Culver , Telligan and Davin are attacked by what they believe to be a robot . However , it is a Dalek . After Davin is exterminated , Culver and Telligan drive their vehicle into it , making it explode . After examining the Dalek , Saxton realises that it is not a robot but a cyborg as it contains organic material . Before the outbreak of the NFS plague , there had been unrest on the Border Worlds . Their inhabitants objected to the centralised bureaucracy of the Galactic Union , claiming they did not understand life on the frontier and had no right to govern them . These political tensions were worsened by the plague , leading to the formation of the Confederation of the Border Worlds Ruling Cabinet . As a result of the NFS plague , Tarkov is suffering from tinnitus and has trouble speaking . While it is unlikely that he is going to die from the plague , he has little chance of recovery . To gather more information about the Daleks and as proof of their intentions , Selestru and Tarkov intend to travel to Velyshaa to interview the elderly Saloran Haredew . Following the arrival of Provost Carneill on Graxis Major , the Graxis system is placed under the jurisdiction of the Dalek Empire . The Daleks claim to be acting on behalf of the Border Worlds Confederation Cabinet .
