Counterstrike

Deadly battles erupt between the Ori, led by Adria, and the Jaffa, after 100,000 villagers are wiped out by a powerful energy wave which Adria believes was SG-1's doing. She captures Daniel and Vala and uses her powers against them to determine the nature of the weapon. Adria learns about the Dakara superweapon and heads there to destroy it. SG-1 are rescued by the Odyssey, but Dakara and its weapon are decimated, fracturing the Free Jaffa Nation.
