The Grand Army of the Light, also known as Army of the Light or the Golden Army, is a vast force of enlightened races that united to combat the Burning Legion in the Twisting Nether and put an end to their future dominance in corrupting every world in the Great Dark Beyond.
The Grand Army of the Light was established by High Exarch Turalyon and Lady Alleria Windrunner, and rallied numerous survivors from several worlds that were taken and broken by the Burning Legion. The Draenei of Argus had survived their world's downfall from the Legion and would join the Grand Army of the Light to avenge their fallen and end the Legion's conquest to rule the entire universe.
Prophet's Lesson EditThis section concerns content exclusive to the Warcraft novels or short stories.
For more than a millennia, many draenei have not forgotten about the Golden Army that was slowly arising to put a end to the Legion. Prophet Velen knew about the Golden Army since he experienced numerous visions of a grand coalition of living or undead races that would soon unite together. Many of the Draenei were foretold that they were part of this grand faction while many of the surviving Naaru were a part of it to stand against the darkness. Along with an innumerable amount of dragons and naaru, the leader of the great coalition was known to be High Exarch Turalyon, however, Velen was unclear who the person was when the vision ended.

Players' struggle against the fel horrors that surround them leads them across the paths of both the paladin Turalyon and the elven ranger Alleria Windrunner. They lead the Army of the Light—a band of lost warriors dedicated to combating the Legion. United in arms with these veterans of Azeroth’s greatest battles, players rally the forces of virtue to strike at the Legion.
Since the naaru tells adventurers about the "Army of the Light" and to seek out <Illidan>, it is highly possible that the naaru provided the original impetus for the formation of the Army of the Light.
