At the dawn of time, when there was nothing but the cold lifeless existence of the forming Universe, there was The Entity. Some believe it was an angel, others claim it was the very first being to achieve self-awareness. This being of light drifted through the cosmos, using its almost unlimited power to seed the first life in the universe. From its manipulations, grew the First Ones and the Celestials, who would take up the cause of the Entity and further spread the gift of living things to all the planets in all of known existence.
After untold eons of toiling, the Entity disappeared, sinking into some far-off world to sleep until it was needed again. While many civilizations have told legends about this being, few have ever found where its resting place lies. Those that have divined its resting place guard it carefully for they know it's important for it to have its well-deserved sleep. Despite this, it has been partially roused by great calamity and has gifted a chosen few with a powerful artifact to battle evil and injustice. A White Power Ring.
Believed to be the inspiration for the Rings wielded by the Various Lantern Corps, the White Lantern Ring shares much of the abilities of the Green Lantern Corps - flight, energy blasts, and solid light constructs. In addition, the light it generates possesses healing properties, capable of regenerating damaged tissue and even reviving the recent deceased. Unlike the other Lanterns, the White Lantern does not have a central power battery. The ring draws power directly from the Entity and never depletes.
Only a few times in its history has a White Lantern appeared. The very last time was during The Shadow War, when the alien Caleen wielded the ring against the forces of darkness himself, even clashing with the likes of Sauron and Darkseid.
Since then, the legends of where he found the Entity has endured to modern times and many would-be wielders of the Light have sought out the lush world that is said to be the Entity's resting place. Few know that the Galactic Empire almost succeeded when they used a tiny moon known as Endor as a base of operations during the Galactic Civil War.
