The galactic crime-syndicate called the Exchange is a group of thugs, gangs, and smugglers, left as a result of the Extermination War.
In the dawn of the 20th Century, Humanity was in a golden age. All were united and were exploring the depths of the solar system and beyond, free of war and crime.
But as they spread throughout the Milky Way, they came into contact with another species. Nicknamed "Ants," they brutally spread out from the home world, sucking planets dry of their resources, and then moving onto the next. The Ants moved in, destroying Human colonies whenever they could.
After the war ended, the Exchange formed, a group of gangs, thugs and thieves that were remnants of the war.
