Hex Syndicate

"' Listen, bud, you need to see that... We don't work for just anybody, we work for those with real credits. We find money, and we spoil ourselves... It's how life should be. We have a real goal, the Republic and those droids can do their own fake goal as long as it doesn't interfere with business.' -Saans Kyro, talking to a Republic agent trying to hire them"

Creation
Saans founded the syndicate once he was able to get free of a Republic prison. He, and a few of his trusted allies, started spreading word of the syndicate. They hired many who sought to make a new life, and sought credits.

Clone Wars
During the Clone Wars, they largely stayed neutral. But on occasions, they would work for the Confederacy of Independent Systems, or The Galactic Republic. Their help and influence was sought after by the factions.

The Empire
Their work was largely un-interrupted by The Empire, and sometimes they helped The Empire. Not much else is known about the fate of the Syndicate during this time, just that they were largely known as pirates, due to their pirate origins.
