GEMINI trap

In 3631 BBY, as part of their ongoing campaign against the Eternal Empire, the Alliance attempted to hijack one of the battlecruisers that made up the Eternal Fleet and replace its GEMINI captain with their newly-acquired GEMINI Prime. However, the GEMINI captain proved more formidable than expected, for unbeknownst to the Outlander and the other Alliance forces, their ally SCORPIO had betrayed them, warning the GEMINI in advance. SCORPIO faked her own "death" during the raid, and used her connection to the GEMINI units to seize the Eternal Throne from Emperor Arcann. The Alliance's forces escaped before Arcann's reinforcements could stop them, and as a result of SCORPIO's machinations, Arcann lost control of the majority of the Eternal Fleet. His losses prompted to launch an all-out assault against the Alliance's base on Odessen in the aftermath.
