Changes

The Warp storms continued to increase for a reason: the birth of [[Slaanesh]], caused by the [[Fall of the Eldar]]. As Slaanesh was finally born the Warp storms ended with a single storm of massive proportions. As the Warp was becalmed the Emperor was able to lead his [[Thunder Warriors]] and later twenty Space Marine Legions from unified Terra to reunite humanity, beginning the [[Great Crusade]] that would create the Imperium.

The [[Age of the Imperium]] officially began with the Emperor's conquest of Terrain the [[Unification Wars]], but in the view of many, truly began with the Great Crusade.
