*As Captain Carter is being promoted to Major, Colonel O'Neill is whisked away to Thor's ship, where the Asgard leader warns him of a Goa'uld plan to attack Earth. Thor offers to help negotiate a peace treaty, and three System Lords - Cronus, Yu, and Nirrti - attend to conference. During the negotiations, however, Teal'c and Cronus are found badly beaten. Yu and Nirrti blame Teal'c and vow retribution until SG-1 uncovers evidence that Nirrti herself was behind the scheme to seize power. Enraged by Nirrti's deception, Cronus and Yu turn against her, and Earth is spared. *Source: Back of card
