The warning
The darkness of space stretched in all directions. Only the cold light of the stars in the far distance gave any illumination to the vault.
The vault, shaped like a green lantern emblem, hung in the void, where it had sat for incalculable millennia.
The vault contained only one small item, one that hardly seemed worth the security that protected it.
The vault held a personal lantern power battery.
To look at, the battery was nothing special. This impression was false. This battery was unique in the entire history of the universe. It alone had never been used to spread it's light.
It was a secret that dated almost to the dawn of time.
What the guardians hadn't ever told anyone, what they had themselves only found out by accident, was that in the time before life, when the darkness fought back against the light, the white light had not broken immediately. It had first bent, and had produced another color to aid it. The tenth color of the emotional spectrum.
The battery housed in the vault at the edge of the universe was silver.
For years the guardians had fed power to the vault, keeping it intact despite the efforts of the battery to break free.
But now the energy had waned. The guardians had failed to keep the flow of energy to the vault continuous during their time commanding the third army and when they where prisoners of the first lantern.
The battery was breaking free.
Soon it would get loose, and silver light would shine through the universe.
Soon, order would be restored.
Soon.
