What about the Patriarch?
Spoiler:-
Did the Patriarch survive at the end? The cut scene at the end of the original Ego Draconis / between ED and DKS showed the Orobas Fjords getting gassed as well when champion harbor was attacked. I don't think I saw him escape his cave but yet somehow you get the wrath of the patriarch spell at the end of DKS
Dragon Slayers never ever killed or encountered actual Dragon, it is even mentioned in the game, perhaps by Patriarch himself. Otherwise they didn't survive. The only know to us case when dragon was killed is the gameplay -- which could not or could be a canon -- one where you can kill a Dragon at the end of DivDiv, after being promoted to Divine One.
