The Seleya was a Vulcan D'kyr-type combat cruiser that was in service with the Vulcan High Command in the mid-22nd century. This ship was under the command of Captain Voris. Its standard crew complement was 147.
In December of 2152, the Seleya embarked on a mission to chart the thermobaric clouds surrounding the Delphic Expanse. After several days, the ship's crew reported that the Seleya was caught in a subspace eddy and being pulled into the Expanse. That was the last transmission ever received from the ship; the Vulcan vessel Vaankara was sent into the Expanse to search for it, but contact with that craft was also soon lost. The final transmission from the Vaankara depicted the crew behaving like animals, and murdering each other. (ENT: "The Expanse")
In September of 2153, Enterprise NX-01 discovered the fate of the Seleya; having made it into the Expanse, the ship had entered an asteroid field to mine trellium ore and refine it into trellium-D, with which the ship's crew could line the vessel's hull and be protected against the anomalies generated by the spheres that littered the region. The ship's complement had quickly been driven insane by neurotoxic effects of the trellium, and the ship remained in the field, adrift.
Although information about the Seleya was stored in the Xindi database aboard Enterprise, this was deleted (along with the rest of the database) shortly after the NX-class starship was seized by Triannon fundamentalists, later in 2153. (ENT: "Chosen Realm") The fact that T'Pol had been exposed to trellium aboard the Seleya led to her becoming addicted to the substance by early 2154. (ENT: "Damage")
Midway through that year, the Vulcan High Command briefly investigated the possibility that Archer had deliberately destroyed the Seleya. Evidence against him included the fact that despite spending several hours in the ship's auxiliary control room, he never attempted to access the internal sensors or download the computer database. He was eventually found innocent, and the High Command saw no reason to investigate the matter further. (ENT: "Home")

The history of the Seleya, as established and explored in the third season of Star Trek: Enterprise, was influenced by that of the Vaankara in the second season finale "The Expanse". Executive Producer Brannon Braga noted, "We thought it would be cool to find one of those Vulcan ships that had vanished." (Star Trek: Communicator issue 151, p. 29)
In the final draft script of "Impulse", the Seleya was initially described thus; "The once-proud vessel is listing, badly damaged by months of asteroid-impacts. The ship is dark, hull pocked and a large section of the 'warp ring' has been ripped away."
In order to film a scene in which away team members from Enterprise hazardously cross a beam in a corridor of the Seleya (while being pursued by the ship's zombie-like affected Vulcan crew), the entire corridor set had to be built eight feet above ground level. An inventive strobing light effect also added to the corridor scenes. "While we had grillworks for floors," remembered Production Designer Herman Zimmerman, "the DP, Marvin Rush, put reflective mirror lighting under the floor that was moving all the time so you got the impression it was lit with strobe lights – it really wasn't, but it was in that direction: bright light/dark shadow, bright light/dark shadow. One of the good things about that was that it made it very mysterious, very horrific." (Star Trek: Communicator issue 151, p. 57)
