Sinestro: With my own eyes, I saw this creature produce fear in our finest warriors and then feed on that fear! There's more: we tracked its trajectory. Parallax is headed to Oa! Never before has an enemy dared to attack us here! You MUST tell me what you know! First Guardian: Will has always been our sole weapon against the forces of darkness in the universe. But as that power began to seem insufficient, a great debate arose among us. Should we exploit another source of power, one we had long since sworn should never be used... fear? But the power of fear was too unpredictable, the chance of corruption too great. And so we decided against it. All of us, that is, except one. Alone, this Guardian entered the forbidden chamber. He wanted to prove the light of fear could be mastered. His intentions were pure, but his hopes were naive. Consumed by the yellow power of fear, the Guardian became the very evil he had wished to destroy. He became Parallax. For the universe's safety and his own, Abin Sur was charged with imprisoning Parallax in the Lost Sector. Sinestro: But he escaped. First Guardian: Feeding on the fear of others, he grew larger, more powerful... Sinestro: ...and he's now headed here to take his revenge on you, and destroy the Corps!... Then we have no choice. We must prepare to harness the power of our enemy, and fight fear with fear. To protect our sectors, we must be able to defend ourselves. We must forge a yellow ring.
