Army of the Light

The Grand Army of the Light, also called the Golden Army, the Army of Light, and the Lightforged, is a faction of enlightened races that the Naaru said would one day combat the ravages of the Burning Legion. After the fall of Argus, the Draenei's finest warriors followed the prime naaru Xe'ra across the cosmos in an eternal war to bring about the Legion's end. Since then, other survivors of the Burning Crusade have joined the ranks of the Lightforged.

Establishment
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
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 and 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.
