Revolt against the Eternal Empire

Around 3635 BBY, the Eternal Empire's rule of the galaxy was challenged by a figure known as the Outlander, who had been imprisoned in carbonite since before the Empire's conquest of both the Galactic Republic and the Sith Empire. Freed from the Eternal Empire's clutches by a small group of allies, the Outlander&mdash;accused of murdering the Immortal Emperor Valkorion by Valkorion's own son Arcann&mdash;went on the run from Arcann's forces, uncovering the legendary starship known as the Gravestone and gaining allies. After Arcann's forces were defeated at the Battle of Asylum, rogue elements from both the Republic and the Sith Empire joined the Outlander's cause, forming the Alliance on the planet Odessen and dedicating themselves to toppling Arcann's rule.
