Rim Worlds of The Greater Collace Rift

There is a region of space, that extends from the middle of subsector District 268 in the Spinward Marches, through the Five Sisters, and into the Urnian Subsector.

The rift is completely empty, with the exception of three worlds, all of which are cut off from the outside universe by a gap crossed only by vessels capable of jumping 3 parsecs, or greater.  The outer rim of the rift, however, is a densely packed ring of worlds, most of which are along the Collace Arm and reachable by jump-1 vessels, and the remainder are all reachable by jump-2 vessels.

The Collace Arm is a navigable grouping of worlds that are all reachable via Jump 1.  The group begins in the Sword Worlds subsector, at the world of Caliburn/1329, and then winds its way down through non aligned space, throughout District 268, until it eventually into the Five Sisters subsector, until it ends at Froin/0539.  But the majority of the worlds are in District 268.

Where the Arm rejoins the Imperium, connecting from Talos/1436 to Mertactor/1537, it comes into the edge of Imperium space that is dominated by the Glisten Subsector. Several of the world in the Five Sisters subsector are also Imperial worlds.  Because of this, travel and trade along the Arm, between Mertactor/1537 and the Five Sisters, is extensive.  Traveling, however, through non-aligned space means that there will not always be recognition of, or support of, ships and/or crew that are openly aligned with the Imperium.  To be sure, there are many factors and worlds that are aspiring client states of the Imperium, but just as many that are fiercely independent.

Coreward of District 268, of course, is the Sword Worlds subsector.  Ships and trading factors out of the Sword Worlds are frequented along the arm, and rimward from District 268, in the Egryn subsector and beyond, are numerous groups of Aslan.  Both of these outside groups have many, many representative populations within the Collace Arm worlds.  A number of rim worlds are also home to several minor races.  And, as the whole of District 268 represents an exposable weakness for the Imperium, as it tries to keep contact with and control over the worlds of the Five Sisters, this means that any number of clandestine Zhodani agents will be operating in the area.

The only known worlds in the Rift are Andor/0236 and Candory/0336 in the Five Sisters Subsector, and world 875-496/0834 in the District 268 Subsector.  It is possible that other, unsurveyed worlds, exist within the Rift.  Curiously, both Andor and Candory have large Droyne populations.
