Unicomplex

A Unicomplex is a location in the fictional Star Trek universe that used as a Borg central base. One of the eight known uncomplexes is located in an unknown area of the Delta Quadrant. It is a center of all processing activity for the Borg collective, and is the home of the Borg Queen. The Uni-Complex resembles a patchwork-like collection of thousands of cubes, connected by assorted conduits and transportation hubs. Borg cubes frequently cross into and out of the Unicomplex on their way to other parts of the galaxy.

In 2377, the Unicomplex was destroyed when a future Admiral Kathryn Janeway unleashed a virus within it, which spread throughout the complex and caused it to self-destruct.

The Borg Collective is highly organized into one collective collective consciousness

The Borg manifest as cybernetically enhanced humanoid drones of multiple species, organized as an interconnected collective, the decisions of which are made by a hive mind, linked to subspace domain. The Borg inhabit a vast region of space in the Delta Quadrant of the galaxy, possessing millions of vessels and having conquered thousands of systems. They operate solely toward the fulfilling of one purpose: to "add the biological and technological distinctiveness of other species to their own" in pursuit of perfection. This is achieved through forced assimilation, a process which transforms individuals and technology into Borg, enhancing, and simultaneously controlling, individuals by implanting or appending synthetic components. The Borg has a hive mind called a queen who controls the rest of the collective or drones. It has physical sub-divisions, Unimatrix and Trimatrix, and it is distributed through out space, primarily the Delta Quadrant and to some extant the Beta Quadrant, with minor incursions at various times upon the Alpha Quadrant.
