Unimatrix 01

Unimatrix 01 was a subsection of the Borg Collective. Drones assigned to this unimatrix operate in close association with the Borg Queen. It contained trillions of drones. 

Some members of Unimatrix 01, including Seven of Nine, crash-landed on a planet and their link with the Collective was temporarily severed. 

Seven of Nine was the tertiary adjunct of Unimatrix 01 until her release from the Collective in 2374. 

Unimatrix 01 was destroyed in 2378 when an alternate future version of Admiral Kathryn Janeway disrupted the collective with her neurolytic pathogen.
