The Barrens

The Barrens was a region within the Alpha Quadrant that was surrounded by a subspace node where no star could exist due to a "curved bubble" of space-time.

Emory Erickson, the investor of the transporter on Earth, travelled onboard the Enterpise (NX-01) to the Barrens in 2154 to use the regions pecuiliar subspace phenomena as a way to save his son, Quinn Erickson, who was trapped in a subspace bubble for 15 years. (ENT episode: Daedalus)
