This include the PTSD they have, the constant self-doubt and depression, and the knowing that they see that they themselves exist only to suffer and to fight? That btw is how I see the WoL's mentality anyway. A veteran of multiple conflicts that is just growing more tired and jaded as the years go on, just wishing for the battles to end. And considering 6.0 is to be the finale of the main conflict, if this were an anime, I'd write it with it being their finale as the WoL, whether it ending through their own death, being depowered and entering retirement, or the title of Azem being passed onto another.
