Part Three : Gloom the Dark Seas . In the Gamma Quadrant , the crew encounters a peaceful species , the Vahni Vahltupani ; while enjoying their hospitality , the planet suddenly is struck by an energy blast . Leaving one of his crew members and many more Vahni dead , Vaughn and the " Defiant " crew head for the energy source – which they finally find on a nearby planet . As the planet ' s atmosphere makes it impossible to scan , Vaughn , Tenmei and Shar decide to take a shuttlecraft to land on the planet , but crash due to the atmosphere . With Shar injured , Vaughn decides to walk to the source of the energy blasts , leaving Prynn to watch over Shar . On the ship , Ezri Dax deals with the fact that , while defending the planet of the Vahni , someone died under her command . The makes an uncomfortable contact with a strange grey matter , that has appeared on the ship . After waking up from coma , Ezri insists that the matter is alive , although sensor readings are confusing . Bashir finally finds out that the matter not only exists in our universe , but also in subspace . Dax manages to get in contact with the being again , and she learns of the planet and its history . A long time ago , a race called the Prentara created some sort of virtual reality when they discovered something they called the Thoughtspace . Unaware of what this really was , the connected their VR to it and the Thoughtspace , essentially being alive , defended itself with the energy blasts . The Prenara called the Thoughtspace being ( s ) the Inamuri . Ezri and the " Defiant " s crew manage to send this information onto the planet , where Shar and Prynn have developed some sort of deeper friendship , as they understand that they share some similarities in their history . Vaughn can finally make use of the information , after having gone through a lot of painful memories , that were apparently created by the Inamuri . However , his action leads to more power eruptions , and the " Defiant " just barely manages to pick up all three of them from the planet , and although it is clear why Prynn and Shar survived ( they wore environment suits ) , the survival of Vaughn remains a mystery . During their stay on the planet , Vaughn ' s confrontation with painful moments and death and Prynn ' being forced to handle a situation of being alone and taking care of a crewmate lead the two to a deeper understanding – Vaughn can finally apologize for not being there for Prynn as her father , when he sent her mother , Ruriko , on an away mission where she died ; recognising that Prynn would have needed him then deeply . And she can finally understand that he had feelings which made it impossible for him to be there for her . Meanwhile on Bajor , while still concerned about Jake Sisko being missing , Kasidy Yates finally tries to make herself at home . She also learns that Kira ' s actions of uploading the old Ohalu text into the Bajoran comm - system might well divide the Vedek Assembly ( see " Avatar , Book Two " ) . Taran ' atar , the Jem ' Hadar " ambassador " aboard DS9 , tries to understand the Alpha Quadrant ' s species – and scares them twice , because in his attempts , he remains shrouded , and once is discovered within a childcare service , and a second time in Quark ' s Bar . Kira explains to him that the people from the Alpha Quadrant need to get accustomed to him . References . John Harriman , Opaka , Benjamin Sisko
