The Terran Alliance are a race of humans who once controlled a vast empire, colonising planets and establishing friendly, peaceful relations with their alien neighbours. They were the first to colonise the Outer Reach. Despite efforts to maintain equality for her citizens, the Outer Reach descended into 100 years of war. At the conclusion of this brutal period, the Dindrenzi Federation controlled the Outer Reach. Allied with the Directorate and the Relthoza, they were spoiling for another fight. The Terran Alliance, however, exhausted by the century-long conflict, were reluctant to respond. But now, after direct attacks at Fathom's Reach, and enemies at the gates, they are driven to action once again.
