The Guardians of the Universe thwarted Yalan by adding a new weakness of wood to his ring, which allowed the club-wielding villagers to overwhelm their oppressor and mortally wound him. The dying Yalan Gur fled into Earth's upper atmosphere, where he merged with his lantern-shaped power battery as he died. His lantern then collided with a fragment of the Starheart and was merged with its magical essence, turning into the Green Flame that becomes the source of Alan Scott's power.
