The Severed Reality
The Grey Movement is created and lead by Grey One, a man older then he lookes.
He created this movement to combat the force behind the coming darkness.
He gathered up strength in the Wilds, when the barbarian Nonac with his aspostate wives wrecked the camp, folowing by an unexpected dark spawn attack.
Many of the thousands of followers died during the two attacks, but they reformed during the first oen and a half year of the blight.
During the Fall of Denerim, The Grey movement showed that they are not dead yet, they were able to save a great number of forces from the doomed city. To regroup in the FrostBack Mountains.
Now they work together with the surviving leadership of Ferelden, Logain and several forces from Orlais and its Chantry.
