What if the unmade are the Heralds? Disillusioned by the repeated tortured they endured at the hands of Rayse, they broke their oaths and joined the enemy. 9 Unmade for the 9 Heralds that were left. Taln is the exception.
Would that be enough to break all of the orders and cause the Recreance? This is all conjecture, but itd be interesting.
