History
Greenworld is a living, sentient planet. It houses the third power outside of Heaven and Hell. The Keeper approached Spawn when he was brought to the world by Heap. He informed Spawn that he cared little for the way between Heaven and Hell. He needed Spawn to return and stop the Armageddon war as it would lay waste to mother nature. He would wipe out the human species before allowing this. Doing so, would eliminate Heaven and Hell's battle for the souls.[1]
