So a few things to start out with. 1. what are we calling the Defensive Line? 2. If the traitor primarchs stay loyal then we need to think of the changes that will happen. (ex. Kurze doesn't blow up Nostramo.) 3. Lets have Erebus be the big traitor, stoking the UM's rage and leading elements of the other legions to Chaos. We could call them the Fallen Legion.
