We all know that the Legions of the World Eaters, Emperor's Children, and Death Guard went through a giant purging. Though I just wanted to see how you guys thought the other legions dealt with the loyal parts of their legions. Perhaps they didn't. We know that as a legion, the Thousand Sons were forced as a whole to become traitors and join Tzteentch. What of the Legions of Perturabo, Night Haunter, and Alpharius?
