Synthetics have been used by corporations and the military of the Inner Planets for generations. The older models were more unpredictable and dangerous. Something happened as they headed farther and farther into The Dark. Many became self aware and over time, have collected into groups and factions beyond the reach of the corporation, fighting a guerilla war against their oppressors. They prey on ships and facilities to obtain supplies for self repair and ship maintenance. It is not uncommon for them to plan missions to assassinate important corporate personnel.
