White Lantern

History
The White Lantern was created by the being Volthoom, following his creation by the Presence. It was used to bestow light unto all of existence, as well as create the Prime Earth and the rest of the universe.

The Origin of the Universe
On the 7th Day of Creation, Volthoom became one with the Lantern, as it lied on Earth.

Around the White Lantern, the monitor Mobius creates a tower, which he dubs the "House of Heroes". Once war broke out on Earth, numerous deities attempted to destroy or obtain the Lantern in search of knowledge and power.

Mobius eventually attempts to destroy the Lantern by stabbing it with his Mobius Sword. The blade splits the Lantern, causing Volthoom to divide into three different energies: Will, Fear, and Rage. The three entities escape from the destroyed Lantern and into space.

The splitting of the Lantern also sent a wave through creation, causing Prime Earth to duplicate itself 52 times; creating the Multiverse.

Blackest Night
Kyle Rayner, Sinestro, and Atrocitus merge entities in order to recreate Volthoom the White Lantern. Nix gives the Mobius Sword to Super-God Rao, who plunges it into Volthoom, sending a beam of Life into Nekron, resurrecting William Hand and bringing life to death.

Return of Bruce Wayne
A Darkseid infected Bruce Wayne going by the name Barbatos travels to the beginning of time in order to recreate the universe in his image. Barbatos knocks back Volthoom and takes the white lantern, but contact creates a reaction that brings evil to life, corrupting the lantern. This corruption creates a polar opposite to creation and life, a concept that will form the entity known as Nekron.
