AKA Belan's Rift (the spelling varies, depending on how the name is transcribed from the original elcor).

A star cluster on the mass relay network, located post-Reaper War between the Crescent Nebula and the Athena Nebula, and thus between Inner Council Space and the Terminus. Named for the elcor explorer Belon/Belan, who first charted it (only in part), it is most notable today as the location of Turvess, homeworld of the raloi.

Belon's Rift was reopened to the galaxy two years after the end of the Reaper War, in 2188.
