Ethan Locken , a former Section 31 agent who is genetically engineered , just like Bashir , and who has now started to build his own , private Jem ' Hadar army on a distant planet . Bashir reluctantly agrees to go after Dr . Locken , and he takes Taran ' atar , Ro and Ezri with him . Julian talks with Elias Vaughn before their departure , and is surprised that he does not seem to be surprised by the existence of Section 31 . After some hours of flying through space , the away - team encounters an unknown Romulan vessel – inside , they find Romulans that have been murdered brutally and a recorded message of Locken ; he seems to think of himself as the new Khan Noonien Singh . When they finally approach the planet , their runabout is shot down by defensive weapons ; while Ro and Taran ' atar can beam out , Julian and Ezri are caught by Locken ' s Jem ' Hadar . While Taran ' atar and Ro , with the help of the Ingavi , a ape - like species that settled on the planet some decades ago , try to reach both their runabout and Dr . Locken ' s headquarters , Dax and Bashir finally meet Locken , who invites them to dinner , shows them his headquarters and does everything to pull Julian on his side . This almost seems to work when Julian , forced to choose between Ezri and Locken , chooses Locken . But he was only pretending , helping Dax to break out of their prison and poison the White of Locken ' s Jem ' Hadar . When Locken realizes Bashir ' s treachery , it is too late – Taran ' atar , having been caught by the other Jem ' Hadar , manages to convince their First that Locken is not a real god , and Locken is finally killed by his own creatures . The crew wants to save some of Locken ' s work for evidence ; however , the headquarters all of a sudden is attacked by Section 31 forces , and they flee from the planet – thinking that the Ingavi are now all killed by Section 31 . Back on DS9 , Vaughn reveals several things to Bashir : first , he is a member of a secret group who has been fighting against Section 31 for a long time ; second , he used the holoship to secretly relocate the Ingavi ; having acquired it following the Section 31 operation in the Briar Patch , which the organisation made look like the fault of one admiral . Bashir joins the secret group , happy to do something against the sinister organization . Kira , in the meantime , gets a message from Shakaar Edon , prime minister of Bajor ; he warns her that with her recent actions ( see " Avatar , Book One " and " Avatar , Book Two " ) , she has made some powerful enemies . Kira realizes that she has not many Bajoran friends left on the station because of her Attainment ; only one security guard , Shul Torem , does not seem to bother with this fact . Also , we learn that ensign Prynn Tenmei is commander Vaughn ' s daughter . Finally , Kasidy Yates and Joseph Sisko find out that Jake Sisko is missing – as he never arrived on Earth , as he was claiming . Breen ; Hirogen ; Species 8472 ; Son ' a ; Srivani ; Tzenkethi
