I agree that the Divine should maybe have spoken to Damian first & explained why it had to happen but the fact still remains that what the Divine did needed to be done.
As for the Divine being the marked one theirs a difference between being marked by a Divine being & being the incrnation of the very being responsable for all the chaos in the world.
Yes the Divines actions gave them a little time because although a war followed, had Yegerna continued with her mission Damian would be a much bigger threat than he already is.
What the Divine did stopped Damian from becoming a unstopable force, Right now he does not possess the strength to defeat the Divine or your Dragon Knight had Ygerna succeeded on the other hand theres no telling what he'd be capable of.
Thats why reserecting her was a mistake that's why she had to die in the first place or there would have been no hope for Riverlon.
The truth is'nt always a nice thing & sometimes it hurts pretty badley but the hardest truths to hear are the best truths to know.
