Regula Badlands

The Regula Badlands was an an area of space made up of intense plasma storms and gravitational anomalies located near the Federation-Romulan border. Despite the unstable nature of the region, it is known to contain a number of planets and planetoids, some of which were inhabited such as Regula II.

In 2377, scouts sent out by the Romulan Star Empire located that the Borg had somehow established a presence in the Badlands, and assimilated a number of planets with a new type of assimilation device. The Romulans immediately shared the intelligence they gathered with the Federation and the Klingon Empire and it was decided that Captain Jean-Luc Picard would lead a taskforce of Starfleet vessels into the Badlands to investigate the Borg threat.

After entering the region, the USS Enterprise-E and the task force encountered a large Borg force operational in the area. Thankfully, the Starfleet force was able to overcome the Borg defenses and reach the Borg's main base in the region. Located near the base was a transphasic nebula which had enabled the Borg to create transwarp conduits to their home territory in the Delta Quadrant. (TNG game: Armada II).
