I know I’m a bit late since it was Shadowlands, but starting the Kyrian campaign and was sort of paying attention to the text. An interesting commonality.
“Behold Ragnaros - the Firelord, he who was ancient when your world was young!”
“Behold our glorious Archon! She who was ancient when this realm was young!”
So is Kyrestia actually Ragnaros in disguise? Or vice-versa? It would explain why it’s been so hard to kill him.
