The Odyssey was in orbit when SG-1 stayed on the planet to collect information about the Ori Army. Se'tak had received information that the planet had followed Origin so he gave the order to use the Dakara superweapon.
When the Odyssey discovered an energy wave from the Stargate fast approaching the village on the planet, the Odyssey managed to beam up SG-1 before the energy wave hit them. Tragically, the energy beam wiped out all life in the village and also killed the crew of an Ori warship.
SG-1 planned to take control of the Ori warship that was left on the planet unmanned but they ran into a Jaffa group led by Bo'rel. They later discovered that the ship took off and left the planet and that it was Adria who steered warship. She had survived the attack of Dakara super-weapon by its pendant. Colonel Cameron Mitchell and Teal'c planned use C-4 to destroy the ship's power generator. Adria used her powers and put them to destroy the generator. Adria waged war ship to Dakara to destroy the super weapon after she had learned about its location after inquiring a Jaffa. (SG1: "Counterstrike")
