Xindi Council planet The Xindi Council planet was the home to the Xindi Council . Its location was top - secret , and the planet was located inside a security zone . The planet was located approximately fifty light year s from the Sol system . The Council chambers were located in a fortress built into a mountain side by the Xindi - Avian s sometime in the 2nd millennium BC . The fortress was two kilometer s above ground level and was perfectly concealed by the cloud layer that surrounded it . The only way in was through the air . After the Xindi weapon ' s location on Azati Prime was discovered by the Human s , it was moved to the Council planet . It was located in a large underground facility in a rocky portion of the planet . ( ) Background information . In the scripts for and , the Council chamber was commonly referred to as " Xindi secret chamber " . In both scripts , it was described as " a large , dark chamber " . However , the script of " The Xindi " referred to the room having " a donut - shaped table in the center , " whereas the " Rajiin " script described the table at the center of the room as " triangular " . Both scripts made reference to " graphics on the table - top " which dimly illuminated the Xindi sitting there . However , no such graphics actually appear in the final version of the room as depicted in those scenes . The set for the Council chamber was built especially for ENT Season 3 premiere and remained standing throughout the entirety of that season . ( " The Xindi " text commentary , ENT Season 3 DVD ) Production Designer Herman Zimmerman noted , " " [ It ] wasn ' t taken down until just before the last show . " " ( ) The set was situated on Paramount Stage 8 . ( text commentary , ENT Season 3 DVD ) Since the production staffers were at first unsure how the Council chamber would work , it was decided only retroactively that the room ' s designers had been the now - extinct Xindi - Avians . " " At the time we knew that there were Insectoids and Reptilians , " " remembered Herman Zimmerman , " " so there ' s a certain look of spurs in the columns , for instance ; later on , that didn ' t work at all as Insectoid or Reptilian , but it worked fine for Avians because talons are like spurs – so we feel we kinda lucked out in choosing that as a " leit motif . " ( ) Herman Zimmerman was additionally instrumental in designing the Council chamber ' s other features , including its access points . " " We had a discussion about , " " he recollected , " " because I ' ve always admired the triangular doorways there , and we emulated a variation [ . . . ] On the columns [ that made up the doorways ] , there ' s a little spot where it juts out , and then juts out again ; [ and ] the spaces between them get wider as you go from the ceiling to the floor . It ' s a minor thing – as most environmental things are in design , you don ' t notice it unless it ' s wrong ! So if you accepted it , then we did our job . We designed the table after some kind of organic fluid look , as much as we could do with ordinary carpentry . The whole room was designed so there were no parallel walls , for instance ; it was a kind of a dead room , soundwise ; it was an interesting way to make a council chamber seem a little more eerie , because people walked down the halls or across the room and there ' s no footfalls , there ' s no sound . " " ( ) In the final draft script of , this planet was commonly referred to as " cloud - covered planet " . The surface of the planet was described thus ; " " The cliffs thrust upwards from a lower cloud layer and disappear into an upper one . . . they seem to hang in space . Clinging precariously to the cliff walls are a cluster of majestic , ancient - looking structures . . . a dizzying , vertical compound suspended in the heavens . " " The script also described this spectacle as an " awe - inspiring sight " and detailed that the first visible representation of the planet ' s Xindi - Avian stronghold was to be " a staggering view of the stronghold in all its vertiginous glory . " Another area of the planet ' s surface ( the Xindi weapon ' s launch site ) was scripted to be " a barren , desert - like plain . " A " temporary residence " in the Avian stronghold was described in the script for " The Council " as " " a sparse suite where Council members reside during off - hours . A window looks out on the massive cloud - cover . " " For " The Council " , a concept sketch of the mountainous Xindi - Avian fortress was drawn by illustrator John Eaves . The image can be seen here . In the final draft script of , this planet was referred to only once , identified as " Council planet " . The same script additionally included a description of the Avian stronghold that echoed the one from the script for " The Council " , describing it as " the cluster of majestic , ancient - looking structures clinging to the towering cliff face seen in ' The Council ' .
