The Eridan Belt.

The Eridan Belt is a region of space that encompasses borders of the United Federation of Planets and the Romulan Star Empire, as well as an expanse extending from these borders towards the galaxy's core regions. This region was accessible from the Z-6 sector and the Tarod sector of the Iota Pavonis sector block. The Eridan Belt was made up of a good deal of space not yet explored by the Federation and Romulans as of the 25th century. (STO mission: "Explore the Eridan Belt")


Amongst the Romulans, there were stories of miners that operated passed the Eridan Belt who discovered alien beacons of unknown origins. (STO mission: "A Day in the Sun") These aliens were the Elachi. (STO mission: "Flight from Virinat")

In 2409, Lieutenant Anek was responsible for Starfleet exploration missions into the Eridan Belt. Most of the systems within the cluster were unknown. (STO mission: "Explore the Eridan Belt") Some of the planets required commodities such as industrial replicators, water purification systems and weather control systems. (STO mission: "Relief Effort")
