Several months after the Odyssey received Asgard upgrades, SG-1 traveled to Dakara in search of the Ark of Truth, an Alteran piece of technology capable of bringing an end to the ori Crusade. Unfortunately, shortly after they uncovered what turned out not to be the Ark, Ori fighters and troops arrived at the planet commanded by Tomin. As he subsequently renounced the Ori and joined the Tau'ri, SG-1 and the Odyssey, commanded by Lt. Col. Cameron Mitchell, set off for the Ori Supergate and the Alteran Home Galaxy.
