The B'Tran Cluster in 2409.

The B'Tran Cluster is a region of space that encompasses borders of the United Federation of Planets, the Gorn Hegemony and the Klingon Empire, as well as an expanse extending from these borders away from the galaxy's core regions, towards the outer rim. This region was accessible from the Mutara sector and the Bellatrix sector of the Gamma Orionis sector block. The B'Tran Cluster was made up of a good deal of space not yet explored by the Federation and Klingons as of the 25th century. Upon returning to local space, the Borg Collective occupied the sector block. Other factions frequenting the B'Tran Cluster included the Undine, Romulan Star Empire, Remans, Hirogen, the Alpha Jem'Hadar and the True Way. (STO video game: Star Trek Online; STO missions: "Explore the B'Tran Cluster", "Chart the B'Tran Cluster")


In 2409, Lieutenant Karbo was responsible for Starfleet exploration missions into the B'Tran Cluster. Most of the systems within the nebula were unknown. (STO mission: "Explore the B'Tran Cluster") Some of the planets required commodities such as entertainment provisions, seismic stabilizers, self-sealing stembolts, terraforming systems and warp coils. (STO mission: "Relief Effort")
