Exiles

The Exiles was a term used in the Galactic Republic space which referred to the Dark Jedi survivors of the Hundred-Year Darkness who were captured and banished into the Unknown Regions. They eventually went on to become the first Sith Lords.

Exile
Although members of the Republic wanted public executions, the Jedi leaders were inclined to banish the rogue Jedi into the unknown in hopes that with time they would see the error of their ways. The fallen Jedi were stripped of their arms and armor and loded into unarmed transports on a barren world by their Jedi captors. They were seen out of charted space by an escort of starfighters and left to jump blindly into the uncharted space outside of the Slice.

Jen'ari
When they emerged from hyperspace, the Exiles found themselves gazing down on an uncharted world. They descended to the surface of the world known as Korriban; there they found a humanoid species calling themselves the Sith. They awed the primitive species with their display of dark side power and forged an alliance with the Sith king's Shadow Hand to gain the confidence of the king and then overthrew him. They declared themselves rulers of the Sith people and became known as the Lords of the Sith, with their leader being called the Jen'ari, or "Dark Lord" of the Sith.

Some of the Exiles, however, were not complacent to rule the Sith and wait to gather their strength. A few of the Dark Jedi returned to the territory of the Republic to attack the Jedi. They believed they now had the power to crush the Jedi Order and rule, but they were wrong. All their premature actions did was alert the Republic and their defenders that some of the Exiles survived out in uncharted space.

Those who remained behind used their alchemical arts to blend their DNA with those of the Sith, allowing their lineage to continue through the Sith species.
