Brainiac starts an all-out war against the Sinestro Corps. The Guardians order the Green Lantern Corps to contain the conflict but to not interfere with it.
After Korugar is practically destroyed, even Hal Jordan is convinced not to interfere. But Hal discovers Brainiac's exobytes in the atmosphere, and just when he finds out that they are draining power from the Sinestro Corps central battery, he is attacked by Sinestro.
"Can you not find the positive in anything? This is practically christmas! Our enemies are tearing each other apart and we're being given free front row seats! Seriously, don't make me come in there and smack your internal monologue around." — Guy Gardner
