The Assassin Overlord is the ruthless leader of the Assassin Clan. He is one of the few original survivors of the great interstellar war. In order to prolong his life hundreds of innocents had to give up their life force over the centuries. His face may look frail and weak but his body is still as powerful and ready to fight as ever thanks to various bionic enhancements. The Assassin Overlord constantly tests the force field around Rukun 9 looking for a way to escape the planet. Should he ever succeed the galaxy would once again be plunged into darkness.
After the last great interstellar war, military conflict was outlawed in the galaxy. All interstellar governments had to send their weapons and armies to the remote planet Rukun 9. The planet was then sealed off by an impenetrable force field ensuring no one would ever have the power to rage war across the stars again.
Since then the galaxy has known peace for hundreds of years. But on Rukun 9 the descendants of the banned armies still continue to rage war. Some fight to protect their people, some fight for power, some fight because they know nothing else. A group of secret guardians makes sure that none of these groups ever finds a way to leave the planet.
Because should the forces banished to Rukun 9 ever escape the planet the galaxy will once again be sink into the chaos of war.
