In this time of conflict, the opportunities for adventure are more exciting than ever before! Forge new trade routes within the Imperium itself. Defend the homeworld from invaders during the Siege of Terra. Make first contact with alien races. Help guide the Terran Confederation in its expansion from a single planet to a star-spanning empire.
