Klephtic Order

The Klephtic Order was a vast network of Human assassins and spies associated with the Black Sun crime syndicate. Their members, known as Klephts, primarily targeted Jedi and other Republic officials in their operations.

History
The Klephts weren't originally associated with the Black Sun, and were originally a resistance movement on their ancestral homeworld, the location and name of which having been lost to history. Artifacts and records lead many historians to believe that the Klephts first appeared in the galactic community as early as 10,000 BBY, having left their liberated homeworld to fight as a mercenary army in the employ of the Galactic Republic's enemies. They largely disappeared from the spotlight, believed to have spent many millennia wandering as pirates or having been disbanded altogether. The Klephts later reemerged during the New Sith Wars and served as mercenaries in the armies of numerous Sith warlords, and on one occasion even fought a war with the Mandalorians in which the Klephts were defeated. They once again went into the shadows for a number of centuries until they reemerged to serve the Black Sun, and made their debut in the media after several terrorist attacks on Trade Federation holdings and the assassination of the director of the Galactic Republic's Judicial Intelligence Bureau (as well as his family and entourage). At the start of the Clone Wars, the Klephts were still a mysterious lot, though were blamed for the deaths of a number of both Separatist and Republic politicians. In 14 BBY, Imperial policemen raided a warehouse on Ord Mantell though to have contained the Klephtic Order's leadership. After the arrest and death of several of the warehouse's occupants, no more killings were traced back to the Klephts, and they were thought to have been wiped from history. Although several terrorist attacks and assassinations well into the New Republic era were credited to the Klephts, it's believed that these claims were false.

The only named individual that was confirmed to have been affiliated with the Klephts was a man named Hajanik, who was killed in a firefight with Sector Rangers after making a failed attempt to sabotage a businessman's transport. Beyond this one record, all other public and government knowledge of the Klephts and their whereabouts were a mystery; this lead many to suspect that they didn't exist at all.

Ideology
Initially, the Klephts identified as an ethnicity of Humans originating from the same star system, however over the following millennia they adopted similar ideologies to the Mandalorians: those that were fit, were able to become Klephts. They became less of a nation and more of a criminal organization over the course of history, however remained shrouded in mystery. It's believed by Republic investigators that recruits were selected by the Klephts, and there was no way to join them without being sought out by them. One individual, a retired bounty hunter from Commenor, claimed that a group of men disguised as Judicial Forces agents attempted to induct him into the Klephtic Order after "keeping tabs on him for months", and was nearly murdered by them when he refused.

Due to the mystery surrounding their nature, it was impossible to pinpoint exactly how they operated, though assassinations confirmed to have involved the Klephts often involved the use of vibroblades and explosives.
