Parallax Sealed in the Central Power Battery
The yellow impurity is unmasked — fear itself, imprisoned.

The story
For decades, Green Lantern rings failed against yellow — the "yellow impurity," a flaw the Guardians never explained. Green Lantern: Rebirth #3 (2005, Johns/Reis) revealed the truth: the impurity was Parallax, the living embodiment of fear, imprisoned in Oa's Central Power Battery since the dawn of the Corps.
The Guardians had sealed Parallax in the Battery to contain it — but its presence tainted every green ring with a weakness to yellow. Worse, it had been whispering to Hal Jordan for years, amplifying his grief over Coast City until he broke. Hal was never simply a villain; he was Parallax's host.
Unmasking Parallax redeemed Hal Jordan and reframed the entire Emerald Twilight saga. The fear entity was resealed, the impurity understood — and the stage was set for the Sinestro Corps War, where fear would return in force.
