Lost Sith

The Lost Sith were a population of Sith exiles, Mandalorians, and other groups from around the galaxy. All of them lived aboard the Lycorax, an integrated mobile planetoid, floating about the edge of the galaxy. They all retained their Dark Sided traditions, and at least half of the population was Force-sensitive. However, rather than the old Sith ultimatum, "Control, and what you can't control, destroy," they believed in simply exacting absolute control over what they could and leaving that which they could not alone. this gave them a remarkable amount of foresight and possessions.

Ethnic Background
The Lost Sith were comprised of many species, cultures, and classes. Among the most common were various exiled Sith, Dark Jedi, Mandalorians, Dathomiri witches, Imperial Remnant deserters, Massissi, true Sith (the species), and various other Force-sensitives.
