Unicomplex The Unicomplex was a vast Borg complex composed of thousands of connected structures and hubs spanning at least 600 kilometers , that housed hundreds of Borg ships and trillions of drones . ( ) It was considered , by the independent drones , to be the home of the Borg Queen . ( ) This complex is likely the closest thing that the Borg have ever had to a physical capital or headquarters . The Unicomplex came under attack in 2375 , when Kathryn Janeway , Tom Paris , Tuvok , and The Doctor took the " Delta Flyer " to rescue Seven of Nine , who was blackmailed into leaving the crew of the . ( ) The Unicomplex was severely damaged and possibly destroyed in 2378 , after the Borg Queen assimilated a neurolytic pathogen from the future Admiral Janeway , who had traveled back in time to bring " Voyager " home . ( ) Background information . It is unclear whether there was more than one Unicomplex . In , the Borg Drone Axum suggested that the independent drones attack the " Primary Unicomplex , " implying that there are other , smaller unicomplexes . When the Unicomplex was introduced in the script of " Dark Frontier " , it was described thus : " " A vast infrastructure of interconnecting modules , grids , technology - - a ' metropolis ' floating in space as far as the eye can see . Dozens of Borg Cubes and Spheres and other Geometric Shapes are flying around the perimeter . This is the sum total of Borg Perfection - - a purely technological world . " " The construction of the Unicomplex had an unusual starting point . Visual Effects Supervisor Mitch Suskin explained , " " We started the Unicomplex with some building blocks that [ Visual Effects Producer ] Dan Curry laid out , which were literally built out of two blocks of wood and some Tinker Toys in his garage . " " ( " Cinefantastique " , Vol . 31 , No . 11 , p . 33 ) Curry was intent on ensuring that the Unicomplex had an atypical shape that was nevertheless consistent with Borg design . ( ) The job of modeling the Unicomplex with CGI , digitally reconstructing Dan Curry ' s maquette , was mostly achieved by Foundation Imaging staffer Koji Kuramura . ( ) However , this task proved to be a difficult one . Remembered Mitch Suskin , " " The real thing , putting it in Borg space , making it look big enough , making it have enough detail , and rendering it , was nightmarish . " " ( " Cinefantastique " , Vol . 31 , No . 11 , p . 33 ) Foundation Imaging ' s Adam " Mojo " Lebowitz commented , " " It was probably the biggest model , polygon - wise , memory - wise , that we ' ve ever had to do for " Star Trek " . So it was a real trick to photograph it . They were really pushing our machines to the limit of what they could do . We had to break things up into multiple tasks . We would actually delete any part of the Unicomplex that wasn ' t seen by the camera from the screen to save memory [ . . . ] One of the animators added a little rail system that went through in one shot just to bring it to life . And we did some nice dark lighting on it to make it look pretty . " " ( ) Although lack of perspective in most exterior shots of spacecraft normally meant that moving the camera seemed as thought the craft itself was instead moving , the multi - layered structure of the labyrinthine Unicomplex allowed for more freedom of the kinds of viewpoints that could be selected . " " With this huge Borg Unicomplex with all this perspective at contiguous levels , " " remarked Lebowitz , " " you could move the camera into a crane shot . We were able to do those kinds of shots in ' Dark Frontier ' because of that model , and normally we can ' t . That was actually one of the first things I got excited about when we saw Dan [ Curry ] ' s design . I knew we would be able to do some nice camera moves that we often can ' t do in space .
