In the 23rd century, humanity entered the age of space colonization. Over time, two major powers emerged: the Earth Federation, centered on Earth and its followers, and the Interstellar Alliance, made up of the trade guilds of the various colonies. Tensions between the political and commercial powers continued to escalate, eventually triggering a thirty-year interstellar war.
At first, the Earth Federation forces won victory after victory thanks to their superior military strength. The Interstellar Alliance, with its advanced technology and vast financial resources, turned the tide by creating super soldiers with enhanced bodies. But the war devastated both sides' economies, and in the end, they signed a peace treaty and formed a united government.
Ten years after the Interstellar United Government was formed, a veteran of the Alliance moved like a ghost from colony to colony, hunting down the surviving members of the Wings of the Stars, a radical group that had once operated within the Interstellar Alliance. This soon caught the government's attention, but it was only the beginning. Before long, senior figures from both the former Earth Federation and the Interstellar Alliance would realize that this man from the past had become an angel of vengeance, and that he would soon have a profound impact on the entire interstellar order.
