Blackest Night

History
Blackest Night is an ancient prophecy of end of all life in the universe. According to the prophecy Earth is the location where it will all start.

Many organizations have different approach to it:
 * The Red Guard seek to stop the coming of the Blackest Night by any means possible, thus they have come to Earth to investigate this planet as it is the foretold birth of the Blackest Night
 * Star Sapphire is sworn to the Lantern Corps in hopes of making a difference against the Blackest Night
 * Sinestro Corps' motives remain to be seen, but Earth is at the center of it, possibly related to the coming of the Blackest Night
 * Blue Disciples have allied themselves with the Lantern Corps in hopes of surviving the Blackest Night (which they do not believe can be avoided, but maintain a firm belief that it can be weathered in order to bring about the Brightest Day)
